Many critics, Descartes himself included, have seen Hobbes as uncharitable or even incoherent in his Objections to the Meditations on First Philosophy. I argue that when understood within the wider context of his views of the late 1630s and early 1640s, Hobbes's Objections are coherent and reflect his goal of providing an epistemology consistent with a mechanical philosophy. I demonstrate the importance of this epistemology for understanding his Fourth Objection concerning the nature of the wax and contend that Hobbes's brief (...) claims in that Objection are best understood as a summary of the mechanism for scientific knowledge found in his broader work. Far from displaying his confusion, Hobbes's Fourth Objection in fact pinpoints a key weakness of Descartes's faculty psychology: its unintelligibility within a mechanical philosophy. (shrink)

Hobbes conception of reason as computation or reckoning is significantly different in Part I of De Corpore from what I take to be the later treatment in Leviathan. In the late actual computation with words starts with making an affirmation, framing a proposition. Reckoning then has to do with the consequences of propositions, or how they connect the facts, states of affairs or actions which they refer tor account. Starting from this it can be made clear how Hobbes understood the (...) crucial application of this conception to natural law, identified as 'right reason'. (shrink)

In this article, I make a philosophical comparison between Hobbes' and Hume's s conceptions of imagination. The article should not be taken as an examination of Hobbes' real effect on Hume's thinking. That is a historical problem I do not address. In addition to being philosophically comparative, the article is expli- cative. Since the subject matter is so broad, I have been compelled to confine myself to the explicative level in my examination. I unfold Hume's conception of imagination, take Juhana (...) Lemetti's interpretation of Hobbes for granted (with some subtle alterations) and then compare my Hume to Lemetti's Hobbes. I will not go into all the details of Hume's rich and many-sided conception and many problems cannot be discussed in the paper; my intention is to shed some light on Hobbes' and Hume's thinking by comparing their conceptions of imagination and their reasons for the conceptions.

It is often suggested that certain forms of early modern philosophy are naturalistic. Although I have some sympathy with this description, I argue that applying the category of naturalism to early modern philosophy is not useful. There is another category that does most of the work we want the category of naturalism to do ? one that, unlike naturalism, was actually used by early moderns.

Several recent commentators argue that Thomas Hobbes’s account of the nature of science is conventionalist. Engaging in scientific practice on a conventionalist account is more a matter of making sure one connects one term to another properly rather than checking one’s claims, e.g., by experiment. In this paper, I argue that the conventionalist interpretation of Hobbesian science accords neither with Hobbes’s theoretical account in De corpore and Leviathan nor with Hobbes’s scientific practice in De homine and elsewhere. Closely tied to (...) the conventionalist interpretation is the deductivist interpretation, on which it is claimed that Hobbes believed sciences such as optics are deduced from geometry. I argue that Hobbesian science places simplest conceptions as the foundation for geometry and the sciences in which we use geometry, which provides strong evidence against both the conventionalist and deductivist interpretations.

During the Italian Renaissance, artists and anatomists compared man to various mechanical devices, in an attempt to uncover knowledge about the structure and processes of the human body. In so doing, they drew on ancient Greek notions of instrumentality and proportion. During the early Scientific Revolution, the metaphor of Man the machine played a key role in the development of mechanistic philosophy. During the Enlightenment, it served views on materialism and atheism. By the nineteenth century, when the Industrial Revolution was (...) in full swing, a fundamental change in the relationship of man to machine had come about. Whereas, for Protagoras, man had been the measure of all things, now suddenly the machine was the standard by which the capacities and limits of man were judged. Man the machine was a key feature in the development of the totalitarian ideology of Communism. Moreover, for over a century now, the technocratic viewpoint has guided many technological innovations. Tracing a history of this metaphor, through Leonardo, Vesalius, Harvey, Descartes, Hobbes, Leibniz, La Mettrie, d'Holbach, Marx and Wells, places man's relationship with technology and his gradual loss of identity since the Renaissance in a new context.
