This essay examines the economics of patronage and the roles of asymmetric information and 
reputation in the early modern reorganization of scientific activities, specifically their influence upon 
the historical formation of key elements in the ethos and organizational structure of publicly funded 
open science. The emergence during the late 16th and early 17th centuries of the idea and practice of 
“open science" represented a break from the previously dominant ethos of secrecy in the pursuit of 
“Nature’s Secrets.” It was a distinctive and vital organizational aspect of the Scientific Revolution, from 
which crystallized a new set of norms, incentives, and organizational structures that reinforced 
scientific researchers' commitments to rapid disclosure of new knowledge.  The rise of “cooperative 
rivalries” in the revelation of new knowledge, is seen as a functional response to heightened 
asymmetric information problems posed for the Renaissance system of court-patronage of the arts 
and sciences; pre-existing informational asymmetries had been exacerbated by increased importance 
of mathematics and the greater reliance upon sophisticated mathematical techniques in a variety of 
practical contexts of application. Analysis of the court patronage system of late Renaissance Europe, 
within which the new natural philosophers found their support, points to the significance of the feudal 
legacy of fragmented political authority in creating conditions of "common agency contracting in 
substitutes." These conditions are shown to have been conducive to more favorable contract terms 
(especially with regard to autonomy and financial support) for the agent-client members of western 
Europe's nascent scientific communities.

From Keeping ‘Nature’s Secrets’ to the Institutionalization of ‘Open Science’ 
Paul A. David 
All Souls College, Oxford & Stanford University 
 In the United States, indeed, throughout the community of industrially advanced nations, 
a sense of urgency has surrounded discussions and debates about the organization and funding 
of R&D by governments.  Surely it is not entirely coincidental that such issues were broached for 
serious discussion in the US during the late 1990s against the backdrop of unprecedentedly large 
contractions in the projected levels of real federal expenditures for both defence-related and 
civilian R&D during 1997-2002.1  Lively debates concerning science policy have erupted in the 
US on many previous occasions, but the most recent episode would seem to have been the first 
sustained that has seen a fundamental questioning of some of the infrastructure institutions and 
organizational  commitments that have framed the nation’s science and technology system -- at 
least since the major restructuring initiated by the 1945 report of Vannevar Bush.2   
Even when the federal funding picture seemed to improve for basic research, opinion- 
leaders in the areas of science and education have continued to ask whether American 
universities should continue to be supported as the primary sites for conducting basic research in 
an “open” fashion which facilitates its close integration with teaching. Some are questioning 
whether the emphasis on research is healthy for undergraduate teaching. Others wonder whether 
an ‘academic research’ environment is compatible with concurrent efforts to expand the sphere 
of collaborative R&D with industry, pro-active forms of “technology transfer,” and to make 
more extensive use of intellectual property and other means of establishing a proprietary interest 
in the research activities of faculty, staff and students?  Might it not be better to hive off both 
basic and applied research into specialized institutes, thus resolving conflicts that arise between 
the universities’ conduct of their traditional functions and the drive on the part of other 
organizations and agencies (both private and governmental) to control information flows in 
order to better exploit new findings?  Issues similar to those concerning the future role of the 
university in the “national innovation system” also have arisen in discussions of moves towards 
‘privatizing’ other publicly funded research institutions such as the National Laboratories, and re- 
orienting national research institutes towards commercial application of their research output 3 
  At a time, when the reorganization of national science and technology systems are under 
active consideration and the fitness of recent experiments with innovations in institutional 
arrangements are undergoing re-assessment, it may be especially useful to look backwards to the 
historical circumstances in which some of the basic institutions of science first emerged; and, 
equally, and to the economic, social and political forces that have shaped their subsequent 
evolution.  Economists quite rightly will wish to continue to probe for deeper understanding 
of the insides of the ‘black box’ of technology (Rosenberg 1982).  But, by comparison with what 
has been learned already concerning institutional arrangements and business strategies affecting 
corporate R&D investments, and the mechanisms enabling private appropriation of research 
benefits, it remains surprising that so much less is known about the economics origins and 
effects of the corresponding institutional infrastructures shaping the world of 'academic' science, 
and about the organization of publicly supported R&D more generally. 
 The desirability of closing this particular lacuna in the economics and economic history 
literature has been just as evident to those who have noticed it within a broader framework of 
concern with the economic analysis of institutions, as to those who have begun to approach that 
task by bringing the perspectives and methods of industrial organization economics to bear in 
the area of science and technology studies.4   Even before the ‘new economics of science’ had 
begun to direct attention to such a program, Douglass North (1990:75) saw a significant 
challenge and an promising opportunity in explicit exploration of “the connecting links between 
institutional structures...and incentives to acquire pure knowledge." 
A variety of historical inquiries may be seen as responses to that challenge, by examining 
key episodes in the institutional evolution of 'public science' and its complex and changing 
relationship with the other organizational spheres of contemporaneous scientific activity.5  The 
latter include, of course, both those in which industrial research was conducted for private 
commercial gain under ‘proprietary rules,’ and the  'defence-related' pursuit of scientific and 
engineering knowledge under conditions of restricted access to information about basic findings 
and their actual and potential applications. Much fascination is imparted to the study of 
institutional evolution in that sphere by the complexity of the organizational details, and the high 
stakes attached to issues arising from the immediate entanglement of R&D programs and project 
with matters of national security; or, alternatively by the strategies and fortunes of business 
corporations that turn on the capabilities of their research organizations.  Nevertheless, the 
historical emergence of the other, academic sphere of research poses a number of questions to 
which the answers seem less intuitively obvious and straightforward, and yet critically important 
as a guide in the formation of constructive science and technology policies. 
Although the conceptualization of science as the pursuit of "public knowledge" and an 
object of public-minded patronage today seems a natural, even a ‘primitive’ notion, it is in reality 
a complex social contrivance. Moreover, “open science” is a social innovation of comparatively 
recent historical origin. This has afforded historians of scientific institutions the archival material 
to examine the evolution of its outward forms of support in considerable detail. But the 
circumstances and interests that gave rise to this innovation, and their relationship to the 
economic forces that have sustained and shaped its subsequent development have not received 
the attention that the importance of the subject in the modern world would seem to warrant. 
 Within university-based research communities, especially, there are recognized norms 
and conventions that constitute a well-delineated professional ethos to which scientists generally 
are disposed to publicly subscribe, whether or not their own behaviors always conform literally 
to its strictures governing the organization and conduct of research. The norms of ‘the Republic 
of Science’ that have famously been articulated by the sociologist Robert K. Merton (1973: esp. 
Ch. 13; 1986: Pt. III) sometimes are summarized under the mnemonic CUDOS: communalism, 
universalism, disinterestedness, originality, skepticism. (See Ziman 1994, p. 177).  The 
‘communal’ ethos emphasizes the cooperative character of inquiry, stressing that the 
accumulation of reliable knowledge is an essentially social process, however much individuals 
may strive to contribute to it.  The force of the Universalist norm is to render entry into 
scientific work and discourse open to all persons of ‘competence’ regardless of their personal 
and ascriptive attributes.  A second aspect of ‘openness’ concerns the disposition of knowledge: 
the full disclosure of findings, and methods, form a key aspect of the cooperative, communal 
program of inquiry. Full disclosure, in turn serves the ethos legitimating and, indeed, prescribing 
what Merton called ‘organized skepticism’; it supports the expectation that all claims to have 
contributed to the stock of reliable knowledge will be subjected to trials of replication and 
verification, without insult to the claimant. The ‘originality’ of such intellectual contributions is 
the touchstone for the acknowledgement of individual scientific claims, upon which collegiate 
reputations and the material and non-pecuniary rewards attached to such peer evaluations are 
 Whence did we come by this distinctive set of governance norms for the search for 
reliable knowledge? How did they become institutionalized as the legitimate ethos -- even where 
they are not strictly adhered to in practice – among the class of academic organizations that 
flourish in the democratic societies of the modern world?  These questions about the nature and 
origins of the fundamental lines of cultural and institutional demarcation that distinguish the 
sphere of ‘open science’ activities -- supported by state funding and the patronage of private 
foundations, and carried on in universities and public (not-for-profit) institutes – form the 
central substantive historical problem that I address in this paper.6  It will be seen that, in the 
particular answers to which I have been led, there also lies a broader message for contemporary 
science and technology policy-making.   
The Problem: Why ‘Open Science”? 
Judged by historical standards, ‘open science' is a comparatively recent organizational 
innovation. Accompanying the profound epistemological transformations effected by the fusion 
of ‘experimentalism’ with Renaissance mathematics, the cultural ethos and social organization of 
western European scientific activities during the late 16th and 17th centuries underwent a 
significant reorganization -- departing from the previously dominant regime of secrecy in the 
pursuit of Nature’s Secrets. This development should be seen as a distinctive and vital aspect of 
the Scientific Revolution, from which there crystallized a new set of social conventions, incentive 
structures, and institutional mechanisms that reinforced scientific researchers' commitments to 
rapid disclosure and wider dissemination of their new discoveries and inventions.  Yet, the 
puzzle of why and how this came about has not received the notice it would seem to deserve, 
especially in view of the completmentarities and tensions that are recognized to be present today 
in relations between the regimes of 'open' and 'proprietary' science.  
 Even superficial reference to the antecedent intellectual orientation and social 
organization of scientific research in the West suggests the utter improbability of the historical 
bifurcation that this involved. For, it saw emerge alongside and in some sense in competition 
with the older, secretive search for ‘Nature's Secrets,’ a new and quite antithetical mode of 
conducting 'the hunt for knowledge.' Virtually all of the intellectual traditions and material 
conditions in the medieval West inveighed against ‘openness’ of inquiry and public disclosure of 
discoveries about the natural order of the world, let alone the heavens.  Medieval experimental 
science, was shaped by a political and religious outlook that encouraged withholding from the 
"vulgar multitude” arcane knowledge that might bring power over material things (see Thorndike 
1950: vol. II; Eamon 1985, 1994).  The imperative of secrecy was particularly strong in the 
medieval and Renaissance traditions of Alchemy, where, indeed, it persisted side-by-side with the 
emergent institutions of open science throughout the 17th and into the 18th century (see Dobbs 
1975, Vickers 1984, Westfall 1980).  Social and economic regulations during the Middle Ages, 
along with the relatively primitive and costly technologies available for scientific 
communications, also reinforced the moral and philosophical considerations arrayed against 
open disclosure of discovered secrets.  Economic rent-seeking worked in the same direction: 
knowledge of recently discovered geographical secrets that were held to be of potential 
mercantile value, such as trade routes, would be kept from the public domain.  Similarly, 
craftsmen normally closely held technological recipes, even when they were not compelled by 
guild restrictions to preserve the 'mysteries' of the industrial arts.7   
 Why then, out of such a background of secrecy and obfuscation, should there have 
emerged a quite distinctive community of inquiry into the nature of the physical world, holding 
different norms regarding disclosure, and being governed by a distinctive reward system based 
upon priority of discovery?  Why so?  The question is striking especially in the modern context, 
where one may see that there is little if any difference between the methods of (scientific) inquiry 
used by university scientists working under the institutional norms of open science, and the 
procedures that they (or others with the same academic training) employ in the setting of a 
corporate R&D laboratory?  Can the social organization of open science then be simply an 
epiphenomenon of the profound philosophical and religious re-orientations that have been 
presented as underpinning the Scientific Revolution, if not the epistemological transformation 
that latter had wrought?  Or, should the intellectual achievements of that epoch instead be read 
as consequences of what might be called the "Open Science Revolution”?  To state the problem 
more synthetically, is it not plausible that these two discontinuities -- the one taking place in the 
social organization of scientific inquiry and the other transforming its intellectual organization -- 
were interdependent, and entangled with each other in ways that need to be more thoroughly 
 A start towards answering this question is provided by considering the economic logic of 
the organization of knowledge-producing activities, for, it is possible in such terms to give a 
complete functionalist account of the institutional complex that characterizes modern science 
(see, e.g., Dasgupta and David 1987, 1994 and David 2003).  In brief, the norm of  'openness' is 
'incentive compatible' with a collegiate reputational reward system based upon accepted claims to 
priority; and it is conducive to individual strategy choices whose collective congruence reduces 
excess duplication of research efforts, and enlarges the domain of informational 
complementarities. This brings socially beneficial ‘spill-overs’ among research programs, and 
abets rapid replication and swift validation of novel discoveries.  The advantages of treating new 
findings as "public goods" in order to promote the faster growth of the stock of knowledge, 
thus, are contrasted with the requirements of secrecy for the purposes of securing a monopoly 
over the use of new information that may be directly or indirectly exploited to produce goods 
and services, or further knowledge. 
There is some explanatory insight in the latter, functional contrast between institutional 
arrangements that are well suited to maximize of the rate of accumulation of knowledge, on one 
hand, and, on the other, social arrangements that suited to maximize a society’s extraction of 
economic rents from the existing state, or stock of knowledge.  This juxtaposition suggests a 
logical basis for the existence and perpetuation of institutional and cultural separations between 
two normatively differentiated communities of research practice, the open 'Republic of Science’ 
and the proprietary 'Realm of Technology’: the two distinctive organizational regimes serve 
different and potentially complementary societal purposes.  
 The foregoing, 'logical origins' style of explanation for the institutions of modern science 
(and technology), however, is one in which all details of their historical evolution are ignored.  
Such a rationale would seem, at best, to presuppose a form of 'creationist' fiction -- namely that 
these arrangements were instituted ab initio by some external agency, such as an informed and 
benevolent political authority endowed with fiscal powers. That objection calls for an explicit 
examination of the 'historical origins' of the institutions of open science, since these remain 
outside the set of 'logical origins" that one arrives at by simply considering the present-day 
functional value of an already extant, cooperative mode of scientific research.    
The Argument: Noble Patrons, Mathematicians, and Principal-Agent Problems 
 Rather than trying to construe the reorganization of scientific activities in early modern 
Europe as having somehow derived automatically from the intellectual changes represented by 
the new style of ‘scientific’ activity, I contend that the historical emergence of the norms of 
disclosure and demonstration, and the rise of 'cooperative rivalries' in the revelation of new 
knowledge, had independent and antecedent roots. These are to be found in the social and 
institutional contexts in which the new breed of scientists of that era were working.  My central 
thesis here is that the formation of a distinctive research culture of open science was first made 
possible, and, indeed, was positively encouraged by the system of aristocratic patronage in an era 
when kings and nobles (both lay and ecclesiastical) were immediately concerned with the 
"ornamental" benefits to be derived by their sponsorship of philosophers and savants of great 
 To support this interpretation, I argue that the economic logic of the patronage system in 
post-Renaissance Europe induced the emergence and promoted the institutionalization of 
reputation-building proceedings, all of which turned upon the revelation of scientific knowledge 
and “expertise” among extended reference groups that included “peer-experts.”  The 
mechanisms involved spanned the range from participation in informal networks of 
correspondence, to public challenges and contests, open demonstrations, and exhibitions and the 
certification of individuals by co-optation and election to "learned societies.”  Patronage, 
however, was an old system in the 17th century, and the sponsorship of intellectuals was a long- 
standing prerogative and responsibility of Europe's social and political elites. It is necessary, 
therefore, explain why something new appeared on the scene; why some of the conventions and 
norms now associated with open science -- in particular, the reliance upon peer appraisal and 
collective evaluation expressed through the formation of professional reputations -- were 
induced in primitive form at this particular juncture in history.  The key propositions for this part 
of my argument derive from first considering the economics of patronage in general, and then 
noticing the specific implications of the newly arising problems of "principal-agent contracting" 
that were created by the encounter of the late Renaissance patronage system with the new 
(mathematical) form of natural philosophy practised by Galileo, Kepler and their 
   Aristocratic patronage systems have reflected two kinds of motivation: the utilitarian and 
the ornamental.  Most political elites, in addition to recognizing some need in their domain for 
men capable of producing new ideas and inventions to solve mundane problems connected with 
warfare and security, land reclamation, food production, transport facilities, and so forth, also 
have sought to enlist the services of those who professed an ability to reveal the secrets of 
Nature, and of Destiny. Kings and princes, and lesser nobles too sought to surround themselves 
with creative talents whose achievements would enhance not only their self-esteem, but also their 
public image -- those aspects of grandeur and ostentatious display that might serve to reinforce 
their claims to rightful authority.  Thus, poets, artists, musicians, chroniclers, architects, 
instrument-makers and natural philosophers found employment in aristocratic courts, both 
because their skills might serve the pleasures of the court, and because their presence "made a 
statement" in the competition among nobles for prestige. These dyadic patron-client 
relationships, which offered the latter material and political support in exchange for service, were 
often precarious, uncomfortably subject to aristocratic whims and pleasures, and to the abrupt 
termination that would ensue on the disgrace or demise of a patron.  Nonetheless, they existed in 
this era as part of a well-articulated system characterized by elaborate conventions and rituals 
that provided calculable career paths for men of intellectual and artistic talents (see Biagioli 1990, 
1993; Moran 1991).  
  Those motives for entering into a patron's role that reduce to symbolic acts of self- 
aggrandizement are here subsumed under the heading "ornamental." Such reasons, however, 
should be understood to have been no less instrumental in their nature and roots than were the 
utilitarian considerations for the patronage of intellectuals.  The public display of "magnificence,” 
in which art and power had become allied, was a stock item in the repertoire of Renaissance 
statecraft (see Strong 1984).  This is significant, because inventions and discoveries that met 
utilitarian needs in some instances would have to be kept secret if they were to be most useful, 
whereas it is in the nature of the ornamental motive that its fulfilment elicits the disclosure of 
new, marvellous discoveries and creations; that the client's achievement on behalf of the patron 
be widely publicized.  Indeed, it was very much in the interest of a patron for the reputations of 
those he patronized to be enhanced in this way, for their fame augmented his own.9   A second 
point of significance is that only some utilitarian services but most ornamental services had 
"positional" value from the patron's point of view.  Although having a skilled artist or a clever 
astronomer in one's court was altogether a good thing; it was far better if such clients were 
personages of greater accomplishments and renown than those who happened to be in the 
service of a rival's court.   The pressure on Europe's ruling families to have intellectuals of 
recognized eminence in their service was thus exacerbated by the existence of rival rulers and 
their courts, and so lent additional strength to the ornamental motives for their patronage of 
such clients.  
 Into this setting a new element had been interjected during the 16th century.  The more 
extensive and rigorous use of mathematical methods formed an important aspect of the work of 
the new breed of natural philosophers.10  But, one surely unintended side-effect of this 
intellectual advance was to render the basis of the mathematically sophisticated savants' claims 
and reputations less immediately accessible for evaluation by the elites in whose service they 
wished to be employed.  The difficulties thereby posed by the asymmetric distribution of 
information were rather unprecedented, not having been encountered to the same degree in the 
patronage of intellectuals and artists who followed other, less esoteric callings. The new breed of 
scientists, however, claimed to specialize in revealing the unfamiliar. Opportunities for 
charlatanry here were more rife, and so were the risks of embarrassment for the patron, should it 
turn out that one had sponsored a fraud -- or much worse, a heretic.  Thus, even where the 
services of the mathematically trained intelligencia might be sought for essentially practical, 
utilitarian motives (such talents being useful in designing machinery for public spectacles, 
surveying and cartography, ballistics and correct use of perspective in pictorial arts), the 
soundness of the candidates' qualifications had become more problematic and far from 
 In other words, this line of argument directs attention to the emergence of especially 
compelling reasons for noble patrons in the late Renaissance to delegate part of the responsibility 
for evaluating and selecting among the new breed of 'savants', devolving those functions upon 
the increasingly formalized communities of their fellow practitioners and correspondents.  
Except for those few who were themselves versed in mathematics or other experimental 
practices associated with the new learning, patrons were inclined to refrain from passing personal 
judgement on scientific assertions and involving themselves in substantive controversies (see 
Biagioli 1993).  It was left to the initiative of the parties dependent upon such patronage to 
organize the production of credible testimonials to their own credibility and scientific status. 
Not altogether surprisingly, therefore, the mid-16th century, which is frequently taken as 
the beginning of the era of modern mathematics, also witnessed the formation of active 
networks of correspondence among Europe's adepts in algebra, announcing newly devised 
techniques and results; this era initiated the modern tradition of publicly posing mathematical 
puzzles, issuing scientific challenges, announcing prizes for the solutions of problems, and the 
holding of open competitions to test the claims of rival experts in the mathematical arts (see e.g., 
Boyer 1985: esp., 310-312; Feingold 1984; Keller 1985).  On the interpretation proposed here, 
the new practices of disclosure constituted a functional response to heightened asymmetric 
information problems that the mathematization of natural philosophy and the practical arts 
posed for the Renaissance system of court-patronage.  
Rival Principals and Common Agency Contracting--The Legacy of European Feudalism 
 The conditions I have sketched regarding the late Renaissance and early modern system 
of court patronage present a situation economists would describe as "common agency 
contracting" involving the competition among incompletely informed principals for the 
dedicated services of multiple agents. This correspondence suggests several noteworthy points 
about the economic organization of scientific activities in Europe during the late 16th and early 
17th centuries. 
  First, since what the scientist-clients had to offer was "novelty,” at any point in time the 
welfare of several patrons could not be jointly advanced in the same degree.  As a consequence 
of the dominance in the early history of modern science of patrons who were concerned with the 
ornamental rather than the utilitarian value of scientist-philosophers, the services a client 
provided to his several patrons were essentially "substitutes" rather than "complementary" 
 Second, in the majority of cases the material rewards offered to clients by any single 
patron were not sufficiently large and certain to free the former from the quest for multiple 
patrons. The situation typically being that of common agency, we may draw on Avinash Dixit’s 
(1996) recent theoretical exposition to point out that in the absence of full information, and 
concerted action on the part of principals, the nature of the incentive contracts offered by the 
latter would reflect their awareness of the possibility that a client/agent could use the means 
provided by one patron to serve the ends of another.  The resulting Nash equilibrium in the 
game among rival principals would then be a set of patronage-contracts that offered clients 
comparatively weak material incentives to devote their efforts exclusively to the service of any 
one patron.  Such an equilibrium outcome, of course, would be consistent with the necessity of 
seeking to serve a number of patrons concurrently (however arduous and demeaning a scientist 
like Galileo might feel that to be); it would thereby reinforce the choice on the part of would-be 
clients of research and publication strategies that would lead towards widening the circle of their 
 Third, as has been shown by Lars Stole’s (1990) analysis of mechanism design under 
common agency contracting, the equilibrium outcome in the case of  "contract substitutes” is in 
general more favorable to the agent than is the case when the services performed for different 
principals are complements.  In effect, the competition among patrons to command the faithful 
attention of an agent/client would lead to contracts that allowed the latter to retain more "rents" 
from the specialized information he possessed.  This provided greater rewards for scientific 
activities than would have resulted otherwise, were there only a single possible patron on the 
scene, or had the patrons predominantly enjoyed positive externalities from others’ support of 
the agent’s efforts -- the characteristic situation where there are significant “spillovers” of 
utilitarian benefits from new knowledge. 
There is in the story related here an historical irony well worth remarking upon, especially 
as it serves also to underscore the tenacity of the past's hold on the incrementally evolving 
institutions that channel the course of economic change.11 The nub of it is simply this: an 
essentially pre-capitalist, European aristocratic disposition to award patronage for the purposes 
of enhancing rulers' political powers symbolically (through displays of "magnificence),” came to 
confer value upon those who pursued knowledge by following the "new science" in the late 16th 
and 17th centuries.  The norms of cooperation and information disclosure within the community 
of scientists, and their institutionalization through the activities of formal scientific organizations, 
emerged -- at least in part -- as a response to the informational requirements of a system of 
patronage in which the competition among noble patrons for prestigious clients was crucial. 
Those rivalries, in turn, were a legacy of western European feudalism: it was the 
fragmentation of political authority that had created the conditions of "common agency 
contracting in substitutes."  An instructive contrast therefore might be drawn with the alternative 
circumstances of a monolithic political system, such as had prevailed elsewhere -- as in the 
Heavenly Empire of China during an earlier epoch, to cite a well-known case of a society that 
clearly possessed the intellectual talents yet failed spectacularly to institutionalize the practice of 
open science. 
Sequelae: Open Science in the ‘New Age of Academies’ 
  The foregoing necessarily brief treatment of immensely complex matters has focused 
upon the economic aspects of patronage in the production of knowledge, and the influence of 
the latter upon the historical formation of key elements in the ethos and organizational structure 
of open science.  Those developments preceded and laid the foundations for the later seventeenth 
and eighteenth century institutionalization of the open pursuit of scientific knowledge under the 
auspices of State-sponsored academies. The Royal Society of London was  founded in 1660 and 
received charters from Charles II in 1662 and 1663, and within another few years, in 1666, the 
Académie Royale des Sciences was created on the initiative of Colbert. The activities of these 
two State foundations, and the ensuing formal institutional ‘reorganization of science’ in Europe 
that they inspired, have received much attention from more than one generation of historians of 
science.12  Although from some perspectives this concentration of scholarly focus might be 
judged inordinate, it may also be justified by the fact that another 70 officially recognized 
scientific organizations have been identified by McCllelan (1985) as having been established 
between the 1660s and 1793, specifically on the models provided by those archetypal 
 Just as I have argued in the foregoing text that the intellectual reorientation represented 
by the scientific revolution cannot be held to have been a motor cause of the emergence of the 
‘open’ mode of searching for Nature’s Secrets, so there are good grounds in the work of other 
scholars for resisting the interpretation of the ‘new Age of Academies’ as constituting a radical 
organizational departure.  Furthermore, there is reason also to contest the view that the so-called 
“New Age of Academies” had been called forth by the enlarged scale and costs of the new 
modes of scientific inquiry, and the supposed failures of private patronage in the mid- 
seventeenth century.13  
The post -1660s phase in the evolution of the institutions of modern science is better 
viewed essentially as the continuation of a much broader cultural movement that had been taking 
place in Europe outside the medieval universities.  One aspect of this movement manifested 
itself in the appearance, around the turn of the sixteenth century, of numerous privately 
patronized scientific societies and ‘academies’.  Seventeenth century science proper thus has been 
found to have played only a very minor part of that wider intellectual reorganization: of the 2500 
learned societies that are known to have been instituted  in Europe between 1500 and 1800, at 
least 700 were formed during the sixteenth century alone. Although some among these 
organizations were scientific in purpose, they were not in the pre-1550 vanguard; according to 
McCllelan (1985), the overwhelming majority were formed in response to interests broader than 
anything that resembling the organized pursuit of science was. 
The following passage from the work of David Lux (1991:pp.189,196) serves well to 
articulate the present state of understanding about the nature of the causal relationships in this 
complicated sequence of developments:  
“[T]he traditional points of departure for discussing organizational change in 
science -- della Porta’s Accademia Secretorum Naturae [founded in Naples, 1589] or 
Cesi’s Accademia dei Lincei [founded in Rome, 1604] -- offer nothing to suggest 
the intellectual novelties of sixteenth-century science produced real organizational 
change....Rather than producing organizational change, sixteenth- and 
seventeenth-century science followed other intellectual activity into new 
organizational forms. Indeed, in strictly organizational terms there is no obvious 
justification for attempting to isolate science from other forms of intellectual 
activity before the end of the seventeenth century.  Nor is there any obvious 
justification for portraying science as honing the cutting edge of organizational 
change. Despite the literature’s claims about novel science creating needs for new 
organizational forms, the institutional history of science across the sixteenth and 
seventeenth centuries actually speaks to a record in which scientific practice 
changed only after moving into new organizational forms.”   
Thus, the institutional context provided by the early academies had readily accommodated the 
needs for “social legitimization” and, for theatres for disclosures where patronage-seeking 
practitioners of the new natural philosophy might enhance their public repute.   Subsequently, the 
institutionalization of the nascent “open science” mode of organization was carried forward 
upon an elevated stage under the aegis of the early modern state, where it mobilized augmented 
resources and applied the new methods of scientific inquiry on a scale that eventually altered the 
character of scientific practice.    
In a still later era, beginning mid-way through the nineteenth century with the 
introduction of modern scientific research into the German state-sponsored universities, mimetic 
inter-institutional competition created a new set “academic market” conditions that proved 
propitious for the establishment of research scientists, and graduate research seminars within the 
ambit of the university. In this new setting, the fundamental problems of reputation and agency  
-- upon which the foregoing economic analysis has been focused – soon re-emerged in different, 
but nonetheless recognizable forms.14 Even today, university patrons, both private and public, 
along with academic administrators, and members of the professoriate find themselves 
confronted by informational asymmetries, agency problems, and reputational reward 
mechanisms that parallel in many respects those that once had characterized the system of 
European court patronage. 
Some things change, however. As the ornamental value of supporting esteemed scholars 
and scientists has given way to the instrumental power of scientific knowledge, the ability of 
individual members of “the Republic of Science” to extract a large part of the “information 
rents” has been circumscribed; correspondingly, there has been an enlargement of the relative 
share of the benefits that flow -- in the form of “knowledge spill-overs” -- to the ultimate 
patrons the publicly supported regime of ‘open science. Yet, some continuities are preserved: in 
the modern system of devolved patronage of science, those having the responsibility for the 
management of academic institutions and non-profit research institutes appear simultaneously in 
the roles of agents vis-à-vis the public, and principals vis-à-vis the research agents upon whose 
expertise they must rely. In their dual capacities the administrators of academic institutions (and 
the individuals who staff them) must continue to seek effective ways of mediating conflicts 
between the divergent interests of the principals and their respective agents. On the one hand, 
they are enjoined to seek the larger societal, public goals that are best served by preserving the 
organizational modes and norms open scientific inquiry; while, on the other hand, they are being 
encouraged to try to appropriate a larger portion of the “information rents” for use in more 
narrowly parochial institutional and private undertakings – even when to do so entails 
circumscribing open access to the new knowledge gained from the research conducted under 
their auspices.    
The moral of all this goes further than merely providing another attestation to the truth 
in the aphorism that the more things seem to change, the more they stay the same.  Some 
important part of the power of modern science today derives from the radical social innovation 
that the ‘open science’ regime constituted.  A corollary proposition, to which the historical 
experience recounted here also lends support, is that the methods of modern science themselves 
have not been, and still are not sufficient to create the unique cultural ethos associated with ‘the 
Republic of Science.’ Nor can they be expected to automatically induce and sustain the peculiar 
institutional infrastructures and organizational conditions of the open science regime, within 
which their application has proved so conducive to the rapid growth of the stock of reliable 
public knowledge, and all that flows therefrom. 
Rather than emerging and surviving as robust epiphenomena of a new organum of 
intellectual inquiry, the institutions of open science are independent, and in some measure 
fortuitous, social and political constructs.  They are in reality intricate cultural legacies of a long 
past epoch of European history, which through them continues to profoundly influence the 
systemic efficacy of the modern scientific research process. 
 Major features of the institutional infrastructure of public science, thus being to a 
considerable degree exogenous to actual scientific practice in the contemporary world, can be 
subjected to substantial amounts of experimental tinkering, and even major re-design, without 
jeopardizing the methodology of current inquiry. In one sense, this freedom this affords the 
manipulation institutional incentives and constraints as instruments of modern science and 
technology policy can be read as “the good news.” 
It should be taken with a grave caution, however: wise policy-making in this sensitive 
area must pay especial heed to those organizational instruments’ own complex and contingent 
histories, and so respect the potential fragility of the institutional matrix within which modern 
science evolved and flourished.  Along with a sense of awe and gratitude for the good fortune of 
having received this remarkable gift from the past, we shall do well to maintain a sobering 
awareness of the extent to which our future welfare has come to depend upon the continued 
smooth workings of an intricate and imperfectly understood piece of social machinery -- one that 
need have no adequate capabilities for self-repair, but readily may be damaged by careless

Lenoir 1998, Lécuyer 1998, and Blumenthal 1998. 
 This paper draws upon David (1997:December), which should be consulted for fuller historical 
documentation and references to the relevant literature. Space there also permits proper 
acknowledgement of the help of Avner Greif, Mario Biagioli, Partha Dasgupta, Weston Headley, 
Scott Mandelbrote, Joel Mokyr, Noel Swerdlow, and many other colleagues, institutions and 
foundations who generously contributed both intellectually and materially in support of my researches 
in area since 1991.  The present essay has benefitted from the  comments and suggestions by Kenneth 
Flamm, Zvi Griliches and David Mowery, which could not be accomodated within David 1998 -- the 
very abridged version read at the  January 1998 AEA Meetings in Chicago, and published shortly 
thereafter in the AEA Proceedings. .  .   
   From the 14th century to the early 18th century in Europe, the issuance of 'letters patent' and 
granting of royal 'privileges' conferring monopoly rights in exchange for the disclosure of 
technological information was aimed primarily at effecting the transfer and application of existing 
industrial arts and engineering practices, i.e., techniques already known to master-craftsmen and 
engineers in other territories; and not at inducing fresh inventive activity. Many early patent 
monopolies were, in effect, local franchises designed to shelter immigrating expert-practitioners from 
the subsequent competition of the apprentices and journeymen they  were expected to train, or others 
who would try imitate them once their particular 'mysterie' had been successfully established in the 
new cities and principalities to which they were recruited. See David and Olsen (1992),  David (1993 
a), and sources cited therein. 
 Galileo’s involvement in the system of court patronage in Italy, and his communications during 
1610 with Kepler, then in the service of Emperor Rudolph II in Prague, is documented by Biagioli 
(1993), and further considered in David (1997:November, pp.32-36). The situations of many other 
notable scientific figures elsewhere in Europe also can be mentioned,  e.g. as by Mokyr (1990: p. 73 
on Leibnitz; p. 84 on Torriceli; p.169 on Borelli.)  See also the extensive discussions in  Moran (1991) 
on the patronage of science and medicine in the court of Prince Henry of Wales (d.1612) at Richmond 
Palace, the Court of Rudolph II and the Habsburg circle in the mid-seventeenth century, the Munich 
Court of Ferdinand Maria, the Elector of Bavaria (r. 1654-1679), and elsewhere in Europe.   
  Galileo understood this well, as was evident from the adroit way in which he exploited his ability to 
prepare superior telescopes for the Grand Duke of Tuscany, Cosimo II de’ Medici: he urged his patron 
to present these to other crowned heads in Europe, whereby they too might observe the new-found 
moons of Jupiter which the Sidereus Nuncius (March 1610) had proclaimed to be “the Medicean 
stars.” See Drake (1957, 1978), Westfall (1985), and Biagioli (1990, 1993: Ch.1).  
. Following the fusion of Arabic and classical mathematics, the significance of algebra, the geometry 
of conic sections, trigonometry, and still more esoteric developments was recognized and openly 
proclaimed in terms that drew upon a rhetorical tradition reaching back to the great Renaissance 
mathematician “Regiomontanus” -- as Johannes Muller of Konigsberg (1432-1476) styled himself. 
See Swerdlow (1993), Boyer (1985: Ch. XV) on Renaissance mathematics; Keller (1985) on the 
program and rhetorical developed on behalf of mathematical training during the 1570's and 1580's; 
Feingold (1984:Ch.IV), Westfall (1985), Biagioli (1989, 1990, 1993) on the patronage of
