We get into the habit of living before acquiring the habit of thinking.
Like great works, deep feelings always mean more than they are conscious of saying. The regularity of an impulse or a repulsion in a soul is encountered again in habits of doing or thinking, is reproduced in consequences of which the soul itself knows nothing. Great feelings take with them their own universe, splendid or abject. They light up with their passion an exclusive world in which they recognize their climate. There is a universe of jealousy, of ambition, of selfishness, or of generosity. A universe—in other words, a metaphysic and an attitude of mind. What is true of already specialized feelings will be even more so of emotions basically as indeterminate, simultaneously as vague and as “definite,” as remote and as “present” as those furnished us by beauty or aroused by absurdity.
-Albert Camus from “The Myth of Sisyphus”
