To enjoy freedom ... we have of course to control ourselves. We must not squander our powers, helplessly and ignorantly, squirting half the house in order to water a single rose.
Don't think in terms of comfort; think in terms of freedom. Don't think in terms of safety, think in terms of being more alive. And the only way to be more alive is to live dangerously, is to risk, is to go on an adventure. And the greatest adventure is not going to the moon - the greatest adventure is going to your own innermost core.
Freedom is independence of the compulsory will of another, and in so far as it tends to exist with the freedom of all according to a universal law, it is the one sole original inborn right belonging to every man in virtue of his humanity.
Pharisaism, obtuseness and tyranny reign not only in the homes of merchants and in jails; I see it in science, in literature, and among youth. I consider any emblem or label a prejudice.... My holy of holies is the human body, health, intellect, talent, inspiration, love and the most absolute of freedoms, the freedom from force and falsity in whatever forms they might appear.
Don't ever forget that you're a citizen of this world, and there are things you can do to lift the human spirit, things that are easy, things that are free, things that you can do every day: civility, respect, kindness, character.
I have always thought that all men should be free; but if any should be slaves, it should be first those who desire for themselves, and secondly those who desire it for others. Whenever I hear anyone arguing for slavery, I feel a strong impulse to see it tried on him personally.
