In this paper, I analyze a momentous change in eighteenth century French life sciences. Whereas in the first half of the century the conception of natural history as the systematic collection of facts had been most successful, at mid-century a new approach emerged. This approach was characterized by an accent on general philosophical themes rather than on observation and experiment. I study the grounds and features of this historical shift through the work of Maupertuis, who published papers in institutional (or (...) Baconian) natural history in his early years, but then adopted a more speculative approach to the life sciences. (shrink)

In Metaphysics Λ7 1072b30–1073a3, Aristotle introduces a Speusippean theory according to which ‘what is most beautiful and best is not en archēi’. Through a detailed analysis of the passage, I argue that Aristotle’s refutation of Speusippus’ thesis is favoured by the introduction of the seed example, which conflates both ontological and temporal priority. The elements gathered from the analysis of Aristotle’s polemical strategy will support a broader conclusion: Speusippus’ reason not to characterise his principle(s) as (the) good is related to (...) the problematic relationship Forms and sensibles had within Plato’s account, or, in other words, participation.

Aristotle’s broad characterization of the soul has been challenged on account of its reliance on the notion of a “potentially alive body”. J. L. Ackrill famously claimed that no body can meet this description without being already actually alive. By a close inspection of both metaphysical and embryological texts, this paper argues that (1) it is embryos (and not fully-formed organic bodies) who provide the right kind of potentially alive subjects and that (2) the schematic character of the soul’s common (...) formula accounts for its seemingly intractable features. It also holds that (3) once the homonymous nature of life is brought into the picture, the κοινότατος λόγος appears unproblematic – at least for some of its most troublesome instances. (shrink)
