"The greatest and saddest defect is not..." - Quote by Henry David Thoreau

“I did not go to Boston, for with regard to that place I sympathize with one of my neighbors, an old man, who has not been there since the last war, when he was compelled to go. No, I have a real genius for staying at home.”

“Every man must walk to the beat of his own drummer.”

“Genius is not a retainer to any emperor.”

“You blocks, you stones, you worse than senseless things!”

“Awareness of ignorance is the beginning of wisdom.”

“I am very conscious that I am not wise at all.”

“The so-called Pythagoreans, who were the first to take up mathematics, not only advanced this subject, but saturated with it, they fancied that the principles of mathematics were the principles of all things.”

“As with stomachs, we should pity minds that do not eat.”

“I try to learn as much as I can because I know nothing compared to what I need to know.”
