Plato
428–348 BC · Ancient Greek
Desire is the soul's restless reaching toward what it lacks; eros is the force that drives the ascent from bodily appetite to the vision of the Good.
Plato's account of desire in the and the is systematic and double-edged. In the , appetite is the lowest part of the soul, the part that craves food, drink, sex, and money. Left ungoverned, it drags the soul downward into tyranny and misery. The tyrannical man, ruled by his appetites, is the most wretched figure in Plato's gallery precisely because his desires are insatiable.
But the tells a different story. There Socrates recounts the teaching of Diotima, who describes eros as a force of ascent. Desire begins with the love of a beautiful body, rises to the love of beautiful souls, then to beautiful ideas, and finally to the contemplation of Beauty itself. Eros is not appetite in disguise; it is the soul's native longing for what is real and eternal. Desire is what moves the philosopher, because philosophy is the love of wisdom, and love always begins in a felt lack.
Plato thus splits desire into two currents. Bodily appetite pulls downward and must be controlled by reason. Erotic longing pulls upward and must be cultivated. The philosophical life is the redirection of desire from lower to higher objects.
"He whom Love touches does not walk in darkness."
"The soul of every man does possess the power of learning the truth and the organ to see it with."
Plato's account leaves two strands for later thinkers: desire as the enslaving force that must be controlled by reason, and desire as the ascending power that, rightly directed, leads the soul toward its highest objects. Both strands recur in the treatments of desire by Aristotle, Augustine, Aquinas, and later writers.
