Famous quotes containing the words exact and/or definition:
“He who asks fortune-tellers the future unwittingly forfeits an inner intimation of coming events that is a thousand times more exact than anything they may say. He is impelled by inertia, rather than curiosity, and nothing is more unlike the submissive apathy with which he hears his fate revealed than the alert dexterity with which the man of courage lays hands on the future.”
—Walter Benjamin (18921940)
“The physicians say, they are not materialists; but they are:MSpirit is matter reduced to an extreme thinness: O so thin!But the definition of spiritual should be, that which is its own evidence. What notions do they attach to love! what to religion! One would not willingly pronounce these words in their hearing, and give them the occasion to profane them.”
—Ralph Waldo Emerson (18031882)
