“What is the Good for man? It must be the ultimate end or object of human life: something that is in itself completely satisfying. Happiness fits this description…we always choose it for itself, and never for any other reason.”

“it is clear that we must trust what is difficult; everything alive trusts in it, everything in Nature grows and defends itself any way it can and is spontaneously itself, tries to be itself at all costs and against all opposition. We know little, but that we must trust in what is difficult is a certainty that will never abandon us; it is good to be solitary, for solitude is difficult; that something is difficult must be one more reason for us to do it.”

“If we do not know the character of being itself - I have never seen anyone suggest that we do know it - then there is an inevitable superficiality in any claim to an exhaustive description of anything that participates in being. And the assertion of the existence, or the nonexistence, of God is the ultimate exhaustive description.”

“Those who make happiness the chief objective of life are bound to fail, for happiness is a by-product rather than an end in itself.”

“Human life must be some kind of mistake. The truth of this will be sufficiently obvious if we only remember that man is a compound of needs and necessities hard to satisfy; and that even when they are satisfied, all he obtains is a state of painlessness, where nothing remains to him but abandonment to boredom. This is direct proof that existence has noreal value in itself; for what is boredom but the feeling of the emptiness of life? If life—the craving for which is the very essence of our being—were possessed of any positive intrinsic value, there would be no such thing as boredom at all: mere existence would satisfy us in itself, and we should want for nothing.”

“The basis of all reasoning is the mind's awareness of itself. What we think, the external objects we perceive, are all like actors that come on and off stage. But our consciousness, the stage itself, is always present to us.”
