A natural reading of Hume’s distinction between impressions and ideas is that impressions are forceful perceptions whereas ideas are faint. A problem emerges, however, when Hume countenances the possibility of faint impressions and forceful ideas. In this paper, I attempt a resolution to the problem. I argue that Hume characterizes impressions and ideas intensionally and extensionally, and sometimes uses the term in only one of the two senses. I argue that Hume intensionally defines impressions and ideas as forceful perceptions and (...) weak perceptions, respectively, but takes these to be extensionally equivalent to original and copied perceptions, respectively. Hume recognizes that his two characterizations—the intensional and extensional—don’t perfectly match up, and that there are exceptions to the purported equivalences (the exceptions being disease, sleep, madness, and enthusiasm). Nonetheless, I argue that Hume’s willing to proceed with his definitions. (shrink)

One Stoic response to the skeptical indistinguishability argument is that it fails to account for expertise: the Stoics allow that while two similar objects create indistinguishable appearances in the amateur, this is not true of the expert, whose appearances succeed in discriminating the pair. This paper re-examines the motivations for this Stoic response, and argues that it reveals the Stoic claim that, in generating a kataleptic appearance, the perceiver’s mind is active, insofar as it applies concepts matching the perceptual stimulus. (...) I argue that this claim is reflected in the Stoic definition of the kataleptic appearance, and that it respects their more general account of mental representation. I further suggest that, in attributing some activity to the mind in creating each kataleptic appearance, and in claiming that the expert’s mind allows her to form more kataleptic appearances than the amateur, the Stoics draw inspiration from the wax tablet model in Plato’s Theaetetus (190e–196d), where Socrates distinguishes the wise from the ignorant on the basis of how well they match sensory input with its appropriate mental ‘seal’ (σφραγίς).

Stoicism was one of the new philosophical movements of the Hellenistic period. The name derives from the porch (stoa poikilê) in the Agora at Athens decorated with mural paintings, where the members of the school congregated, and their lectures were held. Unlike ‘epicurean,’ the sense of the English adjective ‘stoical’ is not utterly misleading with regard to its philosophical origins. The Stoics did, in fact, hold that emotions like fear or envy (or impassioned sexual attachments, or passionate love of anything (...) whatsoever) either were, or arose from, false judgements and that the sage—a person who had attained moral and intellectual perfection—would not undergo them. The later Stoics of Roman Imperial times, Seneca and Epictetus, emphasise the doctrines (already central to the early Stoics' teachings) that the sage is utterly immune to misfortune and that virtue is sufficient for happiness. Our phrase ‘stoic calm’ perhaps encapsulates the general drift of these claims. It does not, however, hint at the even more radical ethical views which the Stoics defended, e.g. that only the sage is free while all others are slaves, or that all those who are morally vicious are equally so. Though it seems clear that some Stoics took a kind of perverse joy in advocating views which seem so at odds with common sense, they did not do so simply to shock. Stoic ethics achieves a certain plausibility within the context of their physical theory and psychology, and within the framework of Greek ethical theory as that was handed down to them from Plato and Aristotle. It seems that they were well aware of the mutually interdependent nature of their philosophical views, likening philosophy itself to a living animal in which logic is bones and sinews; ethics and physics, the flesh and the soul respectively (another version reverses this assignment, making ethics the..

This paper examines some neglected Chrysippean fragments on insecure apprehension (κατάληψις). First, I present Chrysippus’ account of how non-Sages can begin to fortify their insecure apprehension and upgrade it into knowledge (ἐπιστήμη). Next, I reconstruct Chrysippus’ explanation of how sophisms and counter-arguments lead one to abandon one’s insecure apprehension. One such counter-argument originates in the sceptical Academy and targets the Stoic claim that insecure apprehension can be acquired on the basis of custom (συνήθεια). I show how Chrysippus could defend the (...) possibility of custom-based apprehension, while also denying that there is custom-based knowledge. (shrink)

This paper aims to reconstruct the history of the link drawn up by Pseudo-Longinus and Quintilian between phantasia, defined as a faculty of mental visualization, and enargeia, that is the self-evidence of the speech. Actually, the two notions are already linked in the Stoa, which associates enargeia with the « comprehensive representation » (phantasia kataleptike), defined as the support of knowledge and action. The treatise On the Sublime suggests a shift from the Stoic definition of phantasia, considered as « common (...) », to the rhetorical definition of phantasia, presented as the result of a specialization of the first phantasia and still associated with the enargeia. This original relation, taken up by Quintilian, allows to grasp the philosophical background of the rhetorical theories of image and reveals the permeability between the two fields during the Roman period.
