We are full of things which take us out of ourselves. Our instinct makes us feel that we must seek our happiness outside ourselves. Our passions impel us outside, even when no objects present themselves to excite them. External objects tempt us of themselves, and call to us, even when we are not thinking of them.
And thus philosophers have said in vain, “Retire within yourselves, you will find your good there.” We do not believe them, and those who believe them are the most empty and the most foolish.
