Plato’s tripartite soul plays a central role in his account of justice in the Republic. It thus comes as a surprise to find him apparently abandoning this model at the end of the work, when he suggests that the soul, as immortal, must be simple. I propose a way of reconciling these claims, appealing to neglected features of the city-soul analogy and the argument for the soul’s division. The original true soul, I argue, is partitioned, but in a finer manner (...) than how we encounter it in our everyday lives. (shrink)

In the Republic, Phaedrus, and Timaeus, Socrates holds that the psyche is complex, or has three distinct and semi-autonomous sources of motivation, which he calls the reasoning, spirited, and appetitive parts. While the rational part determines what is best overall and motivates us to pursue it, the spirited and appetitive parts incline us toward different objectives, such as victory, honor, and esteem, or the satisfaction of our desires for food, drink, and sex. While it is obvious that Socrates primarily characterizes (...) and distinguishes the parts in terms of what each desires and pursues, what is less often brought to the fore is that he also characterizes and distinguishes the parts in terms of how they think. More specifically, he claims that the rational part forms its beliefs on the basis of rational calculation, while the spirited and appetitive parts form their beliefs on the basis of how things appear, without scrutinizing those appearances. Socrates’ dual characterization of the parts of the soul raises a question: why does he characterize each part as having the particular desires and cognitive abilities that he does? In general, how do facts about what a part desires relate to facts about how it thinks? In this paper, I suggest an answer to this question, one that I hope sheds light on the nature of the parts of the soul and so on Plato’s theory of tripartition more generally. I conclude by showing that Socrates’ theory bears a notable resemblance to contemporary dual process theories of judgment, according to which we have two distinct processes for forming judgments, one which is broadly akin to reflection and another to intuition.

I argue that Plato’s account of hunger and thirst in Republic IV, 437d–439a uncovers a general feature of desire: desire has an unqualified and a qualified dimension. This proposal, which I call Two Dimensions, captures recognizable motivational phenomena: being hungry and aiming to determine what one is hungry for, or wanting to study and still figuring out what field it is that one wants to study. Two Dimensions is a fundamental contribution to the theory of desire. It is compatible, I (...) argue, with the better known premise that desire is for the good, because the objects of paradigmatic desires are inherently valuable. (shrink)

The business ethics field contains a number of explanations for the imagination’s influence on decision-making. This has benefited moral theorizing because approaches that utilize the imagination tend to acknowledge important biological and psychological forces that influence the way we understand situations, develop strategies for problem-solving, and choose courses of action. But, I argue, the broad range of approaches has also served as an obstacle to theory development in the field. Given the variety of theoretical and disciplinary approaches, coupled with the (...) diversity of applications, it would be fair to judge the current state of theory as fractured. To bring focus to theory development, this conceptual study of the moral imagination is grounded in the work of one discipline, one theorist, one text: Plato’s Republic. The primary outcome of this study is the demonstration of the conditions under which the imagination serves to augment and support rationality rather than serving as an impediment. The systematic nature of Plato’s theory aids in the formation of more coherent conceptual grounding than currently available in the field. A final contribution of this study is the positioning of Plato as a proper beginning or foundation to any further theory development in the moral imagination. (shrink)
