Ideas - Thought

Thomas Mann
If you are possessed by an idea, you find it expressed everywhere, you even smell it.

Heraclitus The soul is dyed the color of its thoughts. Think only on those things that are in line with your principles and can bear the full light of day. The content of your character is your choice. Day by day, what you choose, what you think, and what you do is who you become. Your integrity is your destiny-it is the light that guides your way.

Sean O'Casey
You cannot put a rope around the neck of an idea: You cannot put an idea up against a barrack square wall and riddle it with bullets: you cannot confine it in the strongest prison cell that your slaves could ever build.
