This paper investigates the history of a discursive figure that one could call the intelligent whaler. I argue that this figure's success was made possible by the construal and public distribution of whaling intelligence in an important currency of science – facts – in the preparatory phase for the United States Exploring Expedition (1838–1842). The strongest case for the necessity of the enterprise was New England whalers who were said to cruise uncharted parts of the oceans and whose discoveries of (...) uncharted islands were reported in the local press. The document that stood at the core of the lobbying for an expedition was a table that newspaperman and public lecturer Jeremiah Reynolds had compiled after interviewing whaling captains in the country's principal whaling ports. Presenting whalers’ experience in tabular and synoptic form, Reynolds's table helped forge the figure of the ‘intelligent whaler’, a mariner who had better geographical knowledge than other seafarers. By investigating the paper technologies that produced the ‘intelligent whaler’, this paper shows how Reynolds's translation of ‘whaling intelligence’ from news into facts marks the beginning of the intelligent whaler's long career in US-American debates about expansionism, exploration and science.

When we examine the history of astronomy up to the end of the seventeenth century by considering the relation between mathematical astronomy and natural philosophy, it has been argued that there were two groups of philosophers and astronomers: instrumentalists and realists. However, this classification is deficient when we consider attitudes toward the explanatory power of mathematics in determining astronomical theories. I offer the solution of dividing realists into two subcategories—mathematical realists and physical realists. Mathematical realists include those who thought mathematics (...) could provide the real motions of celestial bodies. The physical realists, who include Ibn Rushd (Averroës), believed mathematics could not provide us with the real structure of the heavens. To avoid contradictions between the physical and mathematical models, the physical realists held that a mathematical model of the heavens should be designed by considering physics. I argue, in this article, that Francis Bacon can be considered a physical realist. (shrink)

ArgumentThe purpose of this paper is to provide an analysis of Giordano Bruno’s conception of mathematics. Specifically, it intends to highlight two aspects of this conception that have been neglected in previous studies. First, Bruno’s conception of mathematics changed over time and in parallel with another concept that was central to his thought: the concept of infinity. Specifically, Bruno undertook a reform of mathematics in order to accommodate the concept of the infinitely small or “minimum,” which was introduced at a (...) later stage. Second, contrary to what Héléne Védrine claimed, Bruno believed that mathematical objects were mind-dependent. To chart the parallel development of the conceptions of mathematics and infinity, a seven-year time span is considered, from the publication of Bruno’s first Italian dialogue (La cena de le ceneri,1584) to the publication of one of his last Latin works (De minimo, 1591).
