“He that will not set himself proudly at the top of all things, but will consider the immensity of this fabric, and the great variety that is to be found in this little and inconsiderable part of it which he has to do with, may be apt to think that, in other mansions of it, there may be other and different intelligent beings, of whose faculties he has as little knowledge or apprehension as a worm shut up in one drawer of a cabinet hath of the senses or understanding of a man; such variety and excellency being suitable to the wisdom and power of the Maker. -- 1690”

“You differ from a great man in only one respect: the great man was once a very little man, but he developed one important quality: he recognized the smallness and narrowness of his thoughts and actions. Under the pressure of some task that meant a great deal to him, he learned to see how his smallness, his pettiness endangered his happiness. In other words, a great man knows when and in what way he is a little man. A little man does not know he is little and is afraid to know. He hides his pettiness and narrowness behind illusions of strength and greatness, someone else's strength and greatness. He's proud of his great generals but not of himself. He admires an idea he has not had, not one he has had. The less he understands something, the more firmly he believes in it. And the better he understands an idea, the less he believes in it.”

“An educated man is not, necessarily, one who has an abundance of general or specialized knowledge. An educated man is one who has so developed the faculties of his mind that he may acquire anything he wants, or its equivalent, without violating the rights of others.”

“No enunciation of the Truth will ever be complete, no method of training will ever be suitable for all temperaments, no one can do more than mark out the little plot of infinity which he intends to cultivate, and thrust in the spade, trusting that the soil may eventually be fruitful and free from weeds so far as the bounds he has set himself extend....”

“He who controls others may be powerful, but he who has mastered himself is mightier still.”

“A man may go through life and remain ignorant of himself he may think himself as other than he truly is and he may die with this illusion still intact because no circumstance of his life has obliged him to revise it.”
