"Man, in spite of his tendency towards mendacity, has a great respect for what he calls the truth. Truth is his staff in his voyagethrough life; commonplaces are the bread in his bag and the wine in his jug."
"Art includes everything that stimulates the desire to live; science, everything that sharpens the desire to know. Art, even the most disinterested, the most disembodied, is the auxiliary of life. Born of the sensibility, it sows and creates it in its turn. It is the flower of life and, as seed, it gives back life. Science, or to use a broader term, knowledge, has its end in itself, apart from any idea of life and propagation of the species. Intelligence, that sublimation of the sensibility, that organ of the need to know, is sterilized sensibility. To know, and to know still more--the instinct for knowledge is insatiable, because the subject of knowledge is limitless."
