The Therapy of Desire: Theory and Practice in Hellenistic Ethics, Martha C. Nussbaum draws a comparison between the Hellenistic schools of philosophy and modern philosophy. Here's an excerpt:
The Hellenistic philosophical schools in Greece and Rome—Epicureans, Skeptics, and Stoics—all conceived of philosophy as a way of addressing the most painful problems of human life. They saw the philosopher as a compassionate physician whose arts could heal many pervasive types of human suffering. They practiced philosophy not as a detached intellectual technique dedicated to the display of cleverness but as an immersed and worldly art of grappling with human misery. They focused their attention, in consequence, on issues of daily and urgent human significance—the fear of death, love and sexuality, anger and aggression—issues that are sometimes avoided as embarrassingly messy and personal by the more detached varieties of philosophy. They confronted these issues as they arose in ordinary human lives, with a keen attention to the vicissitudes of those lives, and to what would be necessary and sufficient to make them better. On the one hand, these philosophers were still very much philosophers—dedicated to the careful argumentation, the explicitness, the comprehensiveness, and the rigor that have usually been sought by philosophy, in the tradition of ethical reflection that takes its start (in the West) with Socrates. (They opposed themselves, on this account, to the methods characteristic of popular religion and magic.) On the other hand, their intense focus on the state of desire and thought in the pupil made them seek a newly complex understanding of human psychology, and led them to adopt complex strategies—interactive, rhetorical, literary—designed to enable them to grapple effectively with what they had understood. In the process they forge new conceptions of what philosophical rigor and precision require. In these ways Hellenistic ethics is unlike the more detached and academic moral philosophy that has sometimes been practiced in the Western tradition.
Twentieth-century philosophy, in both Europe and North America, has, until very recently, made less use of Hellenistic ethics than almost any other philosophical culture in the West since the fourth century B.C.E. Not only late antique and most varieties of Christian thought, but also the writings of modern writers as diverse as Descartes, Spinoza, Kant, Adam Smith, Hume, Rousseau, the founding Fathers of the United States, Nietzsche, and Marx, owe in every case a considerable debt to the writings of Stoics, Epicureans, and/or Skeptics, and frequently far more than to the writings of Aristotle and Plato. Especially where philosophical conceptions of emotion are concerned, ignoring the Hellenistic period means ignoring not only the best material in the Western tradition, but also the central influence on later philosophical developments.
