How happy he who can still hope to lift himself from this sea of error! What we know not, that we are anxious to possess, and cannot use what we know.
Johann Wolfgang von GoetheWithout my attempts in natural science, I should never have learned to know mankind such as it is. In nothing else can we so closely approach pure contemplation and thought, so closely observe the errors of the senses and of the understanding, the weak and strong points of character.
Johann Wolfgang von GoetheThere are but two roads that lead to an important goal and to the doing of great things: strength and perseverance. Strength is the lot of but a few privileged men; but austere perseverance, harsh and continuous, may be employed by the smallest of us and rarely fails of its purpose, for its silent power grows irresistibly greater with time.
Johann Wolfgang von GoetheIf one doesn't know one's own country, one doesn't have standards for foreign countries.
Johann Wolfgang von GoetheI could never have known so well how paltry men are, and how little they care for really high aims, if I had not tested them by my scientific researches. Thus I saw that most men only care for science so far as they get a living by it, and that they worship even error when it affords them a subsistence.
