19. Ideas shape the course of history.

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

44. The difficulty lies, not in the new ideas, but in escaping from the old ones, which ramify, for those brought up as most of us have been, into every corner of our minds.

Madmen in authority, who hear voices in the air, are distilling their frenzy from some academic scribbler of a few years back.

52. It is ideas, not vested interests, which are dangerous for good or evil.
