De Anima

Aristotle

Summary

De Anima asks what soul is by beginning with the observable powers of living things. Aristotle reviews earlier accounts from thinkers such as Democritus, Empedocles, Anaxagoras, and Plato, then rejects explanations that make soul either a wandering body, a harmony, or a separate passenger inside the organism. His own definition is hylomorphic: soul is the form or first actuality of a natural organic body that has life potentially. The treatise moves from the most basic powers to the most complex. Plants have nutrition and reproduction; animals add perception, appetite, imagination, and locomotion; human beings add intellect. This order matters because Aristotle does not define life by consciousness alone. He treats living bodies as organized for activity, and he explains mind only after touch, sight, hearing, smell, taste, pleasure, pain, desire, and motion have been considered. The medical and psychological significance is substantial. De Anima is not a medical manual, yet later medicine, psychology, and philosophical anthropology drew on its account of sense organs, common sensibles, phantasia, appetite, and the relation between bodily change and awareness. Touch receives special importance because it belongs to all animals and is tied to survival, nourishment, and pain. Aristotle's active and passive intellect remain among the most disputed passages, but they arise from the same inquiry into how living beings receive forms without becoming the things they know. The work offers an ancient alternative to both material reduction and disembodied spiritualism. Soul is not treated as a ghostly object next to the body; neither is life reduced to inert matter. De Anima instead asks how a body can be alive, perceiving, desiring, moving, remembering, and thinking through powers ordered within a single living form. That vocabulary shaped later debates about sensation, cognition, and the unity of psychosomatic life for centuries. Its abstractions remain tied to animals, organs, and ordinary acts of sensing.

- Summa Theologica, Lesson: Influence without necessity
  Influence without necessity. Aquinas grants that heavenly bodies, humours and even angels and demons can move the passions and imagination, but denies that they compel the will. Most people follow their passions, so predictions about groups often come true, yet any individual can resist. The argument anticipates modern debates about biological influence and responsibility.
