Ideas on Earth were badges of friendship or enmity. Their content did not matter. Friends agreed with friends, in order to express friendliness. Enemies disagreed with enemies, in order to express enmity.

We are healthy only to the extent that our ideas are humane.

Government cannot kill the liberty to think. The idea, the thought, lives forever.

Ideas rise with new mornings but never die.

To make ideas effective, we must be able to fire them off. We must put them into action.
