Psyche
The Greek concept of the soul — originally meaning breath, it evolved to encompass mind, self, and the immortal essence.
The Meaning of Psyche
Psyche originally meant breath — the animating force that leaves the body at death. In Homer, the psyche is a shade, a diminished copy of the living person that flits to Hades as an insubstantial ghost. Achilles's famous declaration that he would rather be a living slave than king of the dead reflects this early conception: the Homeric psyche is barely conscious. But the concept evolved dramatically. The Orphic and Pythagorean traditions taught that the psyche was immortal and divine, trapped in the body as punishment and destined to undergo cycles of reincarnation until purified. Plato synthesized these ideas in the Phaedrus, comparing the soul to a charioteer (reason) driving two horses (spirit and appetite). He argued the soul is self-moving, and what is self-moving is immortal — therefore the soul cannot die. The myth of Psyche and Eros, told by Apuleius, literalises the philosophical journey: the soul (Psyche) achieves immortality through love (Eros).
Fun Fact
Psychology literally means the study of the breath-soul — the Greeks believed consciousness was somehow linked to breathing.
