This paper argues that despite recent tendencies to minimize the differences between Posidonius and the Early Stoics, there are some important aspects of Stoic ethics in which Posidonius deviated from the orthodox doctrine. According to two passages in Diogenes Laertius, Posidonius counted health and wealth among the goods and held that virtue alone is insufficient for happiness. While Kidd in his commentary dismissed this report as spurious, there are good reasons to take Diogenes’ remarks seriously. Through a careful analysis of (...) the sources, in particular of Galen's De placitis Hippocratis et Platonis, this article offers a new interpretation of Posidonius’ ethics. It sheds light on Posidonius’ theory of virtues and shows that Posidonius must have granted a special status to things like health and wealth even if he did not regard them as genuine goods.

The ‘black box’ in Stoic axiology refers to the mysterious connection between the input of Stoic deliberation (reasons generated by the value of indifferents) and the output (appropriate actions). In this paper, I peer into the black box by drawing an analogy between Stoic and Kantian axiology. The value and disvalue of indifferents is intrinsic, but conditional. An extrinsic condition on the value of a token indifferent is that one's selection of that indifferent is sanctioned by context-relative ethical principles. The (...) value of an indifferent that does not meet this condition is normatively silenced, such that it fails to constitute a reason for action. (shrink)

In this article, I vindicate the longstanding intuition that the Stoics are transitional figures in the history of ethics. I argue that the Stoics are committed to thinking that the ideal of human happiness as a life of virtue is impossible for some people, whom I dub ‘hopeless fools.’ In conjunction with the Stoic view that everyone is subject to the same rational requirements to perform ‘appropriate actions’ or ‘duties’ (kathēkonta/officia), and the plausible eudaimonist assumption that happiness is a source (...) of normative reasons only if it is in principle attainable, the existence of hopeless fools demonstrates that the Stoics were pluralists about the ultimate justificatory basis of rational action. Hopeless fools are required to behave just like their non-hopeless counterparts, not because doing so is conducive to their happiness, but because doing so conforms with the dictates of Right Reason.

This article argues that Epictetus employs the terms orexis and hormê in the same manner as the older Stoics. It then shows, on the basis of this claim, that the older Stoics recognized a distinction between dispositional and occurrent forms of motivation. On this account of Stoic theory, intentional action is in each instance the product of two forms of cognition: a value ascription that attributes goodness or badness to some object, conceiving of its possession as beneficial or harmful to (...) the agent, together with a situational judgment about appropriate action. The resulting interpretation suggests that the Stoic theory of motivation as a whole — and not merely the Stoic analysis of the pathê — has the basic shape of a practical syllogism, with more psychological depth than commentators have recognized.

The early Stoics diagnose vicious agents with various psychological diseases, e.g. love of money and love of wine. Such diseases are characterized as false evaluative opinions that lead the agent to form emotional impulses for certain objects, e.g. money and wine. Scholars have therefore analyzed psychological diseases simply as dispositions for assent. This interpretation is incomplete, I argue, and should be augmented with the claim that psychological disease also affects what kind of action-guiding impressions are created prior to giving assent. (...) This proposal respects the Stoic insistence that impression-formation, no less than assent, is an activity of reason. In so far as the wine-lover’s reason is corrupted in a different way from the money-lover’s, the two vicious agents will form different action-guiding impressions when faced with similar stimuli. Here I juxtapose the Stoic account of expertise, according to which experts form more precise action-guiding impressions compared to the amateur, in virtue of possessing a system of grasps (katalēpseis). So expertise enhances, whereas psychological disease degrades, the representational fidelity of the impressions that prefigure action. With these commitments, the Stoics can be seen to offer a nuanced and principled theory of cognitive penetration and to anticipate some recent proposals in epistemology and cognitive science.

This essay considers how ancient Stoic cosmopolitanism – roughly, the claim all human beings are members of the same “cosmopolis”, or universal city, and so are entitled to moral concern in virtue of possessing reason – informs Stoic thinking about how we ought to treat non-human entities in the environment. First, I will present the Stoic justification for the thesis that there are only rational members of the cosmopolis – and so that moral concern does not extend to any non-human (...) part of the natural world – and explore the foundations of these views in Stoic physics. Next, I will show that, like other anthropocentric theories, Stoic cosmopolitanism allows for environmental preservation and protection of non-human entities, so long as these activities ultimately benefit human beings. However, because the Stoics include the appreciation of natural beauty as a component of the happy life, this justification is not as feeble as it might seem. Humans are naturally set up to contemplate the order and complexity of the universe, and so environmental degradation and species loss, in marring this harmonious system, frustrates the achievement of the human goal. After exploring these facets of Stoic philosophy, and assessing to what extent they might justify environmental conservation, I close with a critical appraisal of Stoic theory – specifically, of the claims that (i) only humans possess reason and (ii) only rational creatures are deserving of moral concern.

An overview of the ancient philosophers and their philosophical system (divided into the fields of logic, physics, and ethics) comprising the living, organic, enduring, and evolving body of interrelated ideas identifiable as the Stoic perspective.

This article explores, from an epistemic perspective, the scope of some key notions of the Stoic theory of action at the moment of a rational agent’s deliberation. It is argued that deliberation consists primarily in a critical examination of impulsive presentations (φαντασίαι ὁρμητικαί) and that indifferent objects (ἀδιάφορα), as carriers of a kind of selective value (ἀξία ἐκλεκτική), rather than a reason to act constitute a reason to believe (Klein, 2015). Finally, it is concluded that virtue, contrary to what has (...) sometimes been interpreted, is not part of the deliberative process as one among other considerations about the indifferent because the moral value of virtue is incommensurable with the natural value of the indifferent. However, virtue enters decisively into deliberation insofar as the practical end of the rational agent is to reason perfectly (εὐλογιστεῖν) in full consonance with the demands of destiny. (shrink)
