“ Such is spontaneity. To form a precise idea of the part it plays, we should have to determine, in a general way, and also in relation to temperament, education, social and other conditions, etc., the genesis and development of those faculties by which a given man of superior power is distinguished from his progenitors; we must group together and classify the characteristic elements which make up the very essence of the personality and individuality—those marvelous elements of free initiative and of total independence which stamp a man as a genius. ”
