i propose a revisionist account of the production and reception of galileo's telescopic observations of 1609–10, an account that focuses on the relationship between credit and disclosure. galileo, i argue, acted as though the corroboration of his observations were easy, not difficult. his primary worry was not that some people might reject his claims, but rather that those able to replicate them could too easily proceed to make further discoveries on their own and deprive him of credit. consequently, he tried (...) to slow down potential replicators to prevent them from becoming competitors. he did so by not providing other practitioners access to high-power telescopes and by withholding information about how to build them. this essay looks at the development of galileo's monopoly on early telescopic astronomy to understand how the relationship between disclosure and credit changed as he moved from being an instrument-maker to becoming a discoverer and, eventually, a court philosopher.

The ArgumentI propose a revisionist account of the production and reception of Galileo's telescopic observations of 1609–10, an account that focuses on the relationship between credit and disclosure.

This essay is a contribution to the history of methodological thought. I focus on key methodological criteria for successful experimentation, replication and multiple determinations of empirical evidence. Drawing on reports of experiments with viper venom from the late seventeenth and late eighteenth centuries, as well as on present-day methodological thought I examine whether past experimenters regarded repetition, replication, and multiple determinations as criteria for validity; what exactly they meant by this; what they hoped to gain by repeating, varying, triangulating, and (...) replicating; and how relevant these criteria were for them. I also consider if this analysis has implications for current philosophical work on the methodology of experimental practice. (shrink)

Multiple authorship is so common and pervasive in our world that it is tempting to take it for granted. Prior to the twentieth century, however, multiple authorship was exceedingly rare.

This article is an inquiry into the ties - which the author treats as invisible - that help bind humans in a society. Three forms of the modern Western world can usefully be discerned: patronage, connections and networks. Though retaining continuity, they have succeeded one another in impact and importance. The first mainly characterizes the period of the 16th to 18th centuries; the second, the 19th century, and especially England as it moved from an aristocratic to a bourgeois society; and (...) the third, the late 20th century, with its computer revolution. In general, the direction of change has been from hierarchy to greater equality. Network society, however, is still in its incipient phase, and a final verdict is not yet possible. All three of the types of ties ideally shed light on the societies that they have helped to hold together. (shrink)
