It is the mark of an educated mind...

"It is the mark of an educated mind to be able to entertain a thought without accepting it."
- Aristotle

"It is not the critic who counts, not the man who points out how the strong man stumbled, or where the doer of deeds could have done better. The credit belongs to the man who is actually in the arena; whose face is marred by the dust and sweat and blood; who strives valiantly; who errs and comes short again and again; who knows the great enthusiasms, the great devotions and spends himself in a worthy course; who at the best, knows in the end the triumph of high achievement, and who, at worst, if he fails, at least fails while daring greatly; so that his place shall never be with those cold and timid souls who know neither victory or defeat."
- President Theodore Roosevelt

You don't seem stupid

"You don't seem stupid, so you must be insane."
- Jürgen Prochnow in the movie Primeval

The inner fire...

"The inner fire is the most important thing mankind possesses."
- Edith Södergran, Scandinavian poet

That rifle hanging on the wall...

"That rifle hanging on the wall of the working class flat or labourer’s cottage is the symbol of democracy. It is our job to see that it stays there."
- George Orwell
