This article outlines in details specific experiments that Galen performed. It explores how his methodology for experimentation was a sophisticated response to the rationalist-empirist debate as it occurred in ancient medicine. -/- .

_ Source: _Volume 61, Issue 1, pp 82 - 109 Galen talks about tension, _tonos_, in a physiological sense, which seems to be related to either the innate heat of the living being, the good mixture of its humors, or the body’s _pneuma_. This paper shows that Galen, with some important distinctions concerning the substance of the soul, derives this use of _tonos_ from the Stoics. But beyond that, it shows that Galen uses _tonos_ in a strict psychological sense derived (...) from Plato as well, and integrates it in his characterization of the operations of the spirited part of the soul.

This paper attempts to reconstruct the views of the Stoic Posidonius on the emotions, especially as presented by Galen’s On the Doctrines of Hippocrates and Plato. This is a well-studied area, and many views have been developed over the last few decades. It is also significant that the reliability of Galen’s account is openly at issue. Yet it is not clear that the interpretative possibilities have been fully demarcated. Here I develop Galen’s claim that Posidonius accepted a persistent, non-rational aspect (...) of the soul that he connects with the merely animal part of humans. The aim is to begin from this testimony in answering two questions: (1) How might the possession of a non-rational element of the soul operate alongside the hêgemonikon (leading-part of the soul) as a source of impulse for Posidonius. (2) How does this persistent animal aspect conform to the Stoic ontological classification found in their scala naturae? I shall argue in response to these that (a) Posidonius distinguished the merely cognitive aspects of the soul from those that are rational, and (b) that the hêgemonikon itself is not to be identified with what is rational. Accepting a persistent non-rational source of emotional impulses allows Posidonius a richer framework for explaining human affective responses and behaviours. I also briefly address Galen’s motivation for the account he offers. It is in view of Posidonius’ approach to Plato’s Timaeus that Galen’s discussion finds its most plausible interpretation.

The present article argues that Chrysippus' reply to the objection that Fate does away with that which is up to us (and therefore with justice in honor and punishments) consists in shifting the notion of that which is up to us from one in terms of ultimate origination to one in terms of self-sufficient causation—and thus in shifting the very notion of justice in honor and punishments from one in retributive terms to one in rehabilitative terms.

Seneca’s Letters sketch a theory of attentive action according to which distraction is caused by inconsistent beliefs about values, such that the degree of an agent’s attention to an endorsed action is proportionate to the consistency of her beliefs about value, i. e. her proximity to virtue. The agent’s activity of attentive action is co-ordinated with a state of alertness to her interests, which accordingly triggers switches in attention that sustain the endorsed action in single-minded agents or cause distraction if (...) the new interest is irrelevant to it. Seneca’s theory reflects the older Stoic conception of the tensional mental strength of the virtuous agent, which Chrysippus identified as the causal factor over and above virtue that ensures her successful performance of right action.
