“He who has so little knowledge of human nature as to seek happiness by changing anything but his own dispositions will waste his life in fruitless efforts and multiply the griefs which he purposes to remove”

“The fountain of content must spring up in the mind, and he who hath so little knowledge of human nature as to seek happiness by changing anything but his own disposition, will waste his life in fruitless efforts and multiply the grief he proposes to remove.”

“By the grace of reality and the nature of life, man–every man–is an end in himself, he exists for his own sake, and the achievement of his own happiness is his highest moral purpose”

“He was a vegetable, so trying to change his mind was fruitless.”

“The whole effort for the past one hundred years has been to remove the moral responsibility from the individual and make him blame his own human wickedness on his society, but he helps to make his society, you see, and he will not take his responsibility for his part in it.”

“Every man who knows how to read has it in his power to magnify himself, to multiply the ways in which he exists, to make his life full, significant and interesting.”
