“Every industrious man, in every lawful calling, is a useful man. And one principal reason why men are so often useless is that they neglect their own profession or calling, and divide and shift their attention among a multiplicity of objects and pursuits.”

“All rational knowledge is either material, and concerns some objects, or formal, and is occupied only with the form of understanding and reason itself and with the universal rules of thinking, without regard to distinctions among objects. formal philosophy is called logic. Material philosophy, however, which has to do with definite object objects and the laws to which they are subject, is divided into two parts. This is because these laws are either laws of nature or laws of freedom. The science of the former is called physics, and that of the latter ethics. The former is also called theory of nature and the latter theory of morals.”

“I have come to the conclusion that one useless man is called a disgrace, that two are called a law firm, and that three or more become a CONGRESS!”

“People often think the question of non-resistance to evil by forceis a theoretical one, which can be neglected. Yet this questionis presented by life itself to all men, and calls for some answerfrom every thinking man. Ever since Christianity has beenoutwardly professed, this question is for men in their social lifelike the question which presents itself to a traveler when theroad on which he has been journeying divides into two branches.He must go on and he cannot say: I will not think about it, butwill go on just as I did before. There was one road, now thereare two, and he must make his choice.”

“Every honest man lives for himself. Every man worth calling a man lives for himself. The one who doesn't - doesn't live at all.”

“Every man has his secret sorrows which the world knows not; and often times we call a man cold when he is only sad.”
