Who said “It is ideas, not vested interests, which are dangerous for good or evil.”?

“Ideas too are a life and a world.”

“All achievement, all earned riches, have their beginning in an idea! p.18”

“An idea that is not dangerous is not worthy of being called an idea at all.”

“If you are possessed by an idea, you find it expressed everywhere, you even smell it.”

“Ideas are refined and multiplied in the commerce of minds. In their splendor, images effect a very simple communion of souls.”

“In the long run we are all dead.”

“Nothing mattered except states of mind, chiefly our own.”

“Words ought to be a little wild for they are the assaults of thought on the unthinking.”

“Most men love money and security more, and creation and construction less, as they get older.”

“A study of the history of opinion is a necessary preliminary to the emancipation of the mind.”

“I do not know which makes a man more conservative -- to know nothing but the present, or nothing but the past.”
