In the Fourth Meditation, Descartes famously treats the indifference of the will (roughly, ambivalence of reasons) as the source of error, which many read as oddly suggesting that the will judges arbitrarily. In his letter to Elisabeth dated 1st September 1645, however, he expressly takes passions to be the source of error, saying that passions move the will to judge erroneously by misrepresenting the value of objects. Although these two accounts focus on different kinds of error – theoretical and practical (...) error, respectively – I argue that Descartes is best understood as extending the second account also to the source of theoretical error. On my reading, the first account does not imply that erroneous judgements are simply arbitrary, but it leaves out an explanation why we judge at the time we do, when we could (and should) continue to inquire insofar as we have not yet gathered sufficient evidence. The second account fills in this lacuna by giving an explanation in terms of passions. I further argue that the schematic nature of the first account is due partly to the structure of the Meditations, but mainly to the fact that Descartes has not yet systematically examined the nature of passions there.

Commentators commonly assume that Descartes regards it as a function of the passions to inform us or teach us which things are beneficial and which are harmful. As a result, they tend to infer that Descartes regards the passions as an appropriate guide to what is beneficial or harmful. In this paper I argue that this conception of the role of the passions in Descartes is mistaken. First, in spite of a number of texts appearing to show the contrary, I (...) argue that Descartes does not regard it as the role of the passions to inform us about what is beneficial or harmful. Second, although Descartes calls the passions good and useful, I argue that Descartes does not think we should allow ourselves to be guided by them. When we recognize that the function of the passions is largely motivational and not informative, we can more easily understand Descartes's practical advice in The Passions of the Soul that happiness requires us to guide our passions instead of letting our passions guide us.

This paper contributes to a better understanding of Cartesian irresolution by clarifying its relation to akrasia and wantonness. It argues that irresolution (qua passion) is the same as neither akrasia nor wantonness, but is, like them, a kind of weakness of soul. If akrasia consists in having what Descartes calls ‘firm and decisive judgments’ (F&D judgments) but failing to act on them, and wantonness consists in not having any F&D judgments at all, but acting completely at the behest of the (...) passions, then irresolution can be understood as a state between akrasia and wantonness: the irresolute lacks F&D judgments (like the wanton) but (unlike the wanton) actively strives to attain them.

Descartes’ theory of the passions has important connections to his view that nonhuman animals are automata. In this paper, I show how critics of animal automatism exploited these connections. I int...
