Many philosophers today approach important psychological phenomena, such as weakness of the will and moral motivation, using a broadly Humean distinction between beliefs, which aim to represent the world, and desires, which aim to change the world. On this picture, desires provide the ends or goals of action, while beliefs simply tell us how to achieve those ends. In the Republic, Socrates attempts to explain the phenomena using a different distinction: he argues that the human soul or psyche consists in (...) reason, spirit, and appetite. It is initially tempting to assimilate Socrates’ picture to the standard belief ⁄ desire model, and to think that reason’s role in motivating action is restricted to calculating the best means for satisfying spirited and appetitive desires. But this would be a mistake, since Socrates thinks that each element in the soul is capable of setting the ends of action. But then how exactly should we understand these elements? My aim in this essay is to introduce the reader to Plato’s theory of the tripartite psychology. In part 2, I present Socrates’ argument for the claim that the soul has three elements. In part 3, I provide a general characterization of reason, spirit, and appetite, respectively. I then turn to discuss two central interpretive issues. In part 4, I discuss the sense in which Socrates considers the appetitive and spirited elements to be non-rational. And in the final part of the essay, I discuss the issue of how we ought to conceive of the parts of the soul, and more specifically, whether we should think of them as agent-like parts, or in some other way.

Many academics and researchers who publish scholarly articles on Plato’s philosophy of education claim that the ultimate educational goal for Plato is simply the acquisition of virtues. While such a claim may not be entirely incorrect, it is nevertheless substantially wanting; for although the acquisition of virtue is no doubt paramount, for Plato it primarily serves as a means to another end. In this paper, I aim to show that, for Plato, the final summit of all educational enterprise is not (...) really to become virtuous but rather to attain the state of becoming like God, and that is, homoiōsis theōi. -/- .

Three times in Book 1 chapter 13 of the Nicomachean Ethics, Aristotle says desire partakes of reason in a way. There is a consensus view in the literature about what that claim means: desire has no intrinsic rationality, but can partake of reason by being blindly obedient to the commands of reason. I argue this consensus view is mistaken: for Aristotle, adult human desire has its own intrinsic rationality, and while it is to be obedient to reason, it is not (...) blind obedience, for when reason tells desire to obey, it includes an explanation supporting its order which desire can at least potentially understand. Thus, the nature of human desire, and also of the characteristic interaction of desire and reason, is much different than it is standardly taken to be. (shrink)

This essay argues that Plato in the Republic needs an account of why and how the three distinct parts of the soul are parts of one soul, and it draws on the Phaedrus and Gorgias to develop an account of compositional unity that fits what is said in the Republic.

In the Phaedo, to explain why the philosopher lives in the unusually ascetic way he does, Socrates explains what someone realizes when philosophy takes possession of his soul and how he changes his behavior on the basis of this information. This paper considers the conception of belief the character uses in this explanation and whether it is the same as the conception Michael Frede thinks the historical Socrates is likely to have held and that the Stoics much later incorporated into (...) their doctrine of practice.

The partition of the soul is used extensively, both in Book iv and in Books viii-ix of the Republic, to describe and to explain the structure, growth, and decay, of just and unjust cities and souls. Plato has in mind a single conception of the three parts of the soul, and he expounds it gradually. He recognizes different grades of rationality in desire. These grades help us to understand the roles of the partition of the soul in Plato’s argument.

To what extent is possession of truth considered a good thing in the Republic? Certain passages of the dialogue appear to regard truth as a universal good, but others are more circumspect about its value, recommending that truth be withheld on occasion and falsehood disseminated. I seek to resolve this tension by distinguishing two kinds of truths, which I label 'philosophical' and 'non-philosophical'. Philosophical truths, I argue, are considered unqualifiedly good to possess, whereas non-philosophical truths are regarded as worth possessing (...) only to the extent that possession conduces to good behaviour in those who possess them. In the non-philosophical arena it is an open question, to be determined on a case-by-case basis, whether falsehood is more efficacious in furthering this practical aim than truth. (shrink)

The spirited part, thumos, plays a complex and often disputed role in Plato's account of the soul. The doctrine of the soul as specifically tri‐partitioned seems to depend on a substantial conception of thumos as fundamental and non‐reducible. Building on John Cooper's contribution in the discussion of the topic, this article aims to show that the role of thumos is characterised by an indispensable, deep‐rooted urge for dignified self‐preservation. The view is supported by Plato's own examples, and discussed with regards (...) to Myles Burnyeat's account of thumos as an essentially social phenomenon. The main claim is that in order to preserve the Platonist idea of thumos as fundamental one should discard Burnyeat's characterisation of thumos as unequivocally social, and instead advocate a view of thumos as concerned with a particular form of self‐preservation, which Cooper's account suggests, but does not fully elaborate.

The ethics and moral psychology of the Phaedo crucially depend on claims made uniquely about bodily desire. This paper offers an analysis and defense of the account of bodily desire in the dialogue, arguing that bodily desires – desires with their source in processes or conditions of the body – are characterized by three features: motivational pull, assertoric force, and intensity. Desires with these features target the soul’s rational functions with distinctive forms of imprisonment. They target the soul’s capacity to (...) rule with servility; and they target the soul’s capacity for knowledge with confinement in the visible world. (shrink)
