What Is the Philosophy of Emotion?

Quick Answer

The philosophy of emotion is the branch of philosophy that studies emotions as objects of philosophical investigation. It asks foundational questions: What is an emotion? Are emotions rational? Can emotions be assessed as appropriate or inappropriate? How do emotions relate to knowledge, action, and morality? The field sits at the intersection of the philosophy of mind, moral psychology, and ethics.

Unlike psychology, which studies emotions empirically, philosophy studies the concepts, norms, and structures involved in emotional life. The two disciplines inform each other, but their questions are distinct.

What Is the Philosophy of Emotion?

The philosophy of emotion has several core areas. The metaphysics of emotion asks what kind of thing an emotion is: a feeling, a judgment, a perception of value, or a syndrome of elements. The epistemology of emotion asks whether emotions can be sources of knowledge — whether, for example, fear can tell us something about danger or compassion about what matters.

The ethics of emotion asks what role emotions should play in a good life and in moral judgment. Are some emotions virtuous? Is emotional response part of moral perception? Can emotions be trained? These questions run from Aristotle's account of the virtues to contemporary moral psychology.

Historical Background

The philosophy of emotion is ancient. Plato treated the passions as forces requiring rational governance. Aristotle argued in the Rhetoric that emotions involve judgments — anger involves the judgment that one has been slighted — and in the Nicomachean Ethics that the virtuous person feels emotions at the right times, toward the right objects, to the right degree.

The Stoics radicalized this cognitive approach: emotions are judgments, and because they typically involve false judgments about what matters, the wise person works to eliminate them. The Hellenistic debate framed the topic for centuries.

The eighteenth century brought sentiment into the center of moral philosophy. Hume argued that moral distinctions are grounded in sentiment, and Adam Smith's The Theory of Moral Sentiments analyzed sympathy as the basis of moral judgment. The nineteenth century sharpened the vocabulary of emotion, feeling, and affect, as the SEP entry on emotions in the eighteenth and nineteenth centuries documents.

Key Arguments

Contemporary philosophy of emotion organizes itself around rival theories. Feeling theories identify emotions with felt experiences. Cognitive theories identify them with judgments or beliefs. Appraisal theories treat emotions as evaluations of situations relative to the subject's concerns. Perceptual theories treat emotions as perceptions of values.

Each theory handles different evidence well. Feeling theories capture the phenomenology; cognitive theories capture rationality and intentionality; appraisal theories capture the role of personal concern. Nussbaum's Upheavals of Thought defends a broadly cognitive view on which emotions are judgments about the importance of external goods — judgments that are central to a human life, not peripheral to it.

Contemporary Relevance

The philosophy of emotion now shapes debates in ethics (are emotions needed for moral judgment?), epistemology (can emotions justify beliefs?), aesthetics (what is emotional expression?), and artificial intelligence (can machines have emotions?). It also informs how we think about education, relationships, and the good life.
