Love animals: God has given them the rudiments of thought and joy untroubled. Do not trouble their joy, don't harrass them, don't deprive them of their happiness, don't work against God's intent. Man, do not pride yourself on superiority to animals; they are without sin, and you, with your greatness, defile the earth by your appearance on it, and leave the traces of your foulness after you - alas, it is true of almost every one of us!
Love is free; to promise for ever to love the same woman is not less absurd than to promise to believe the same creed; such a vow in both cases excludes us from all inquiry.
When you make loving others the story of your life, there's never a final chapter, because the legacy continues. You lend your light to one person, and he or she shines it on another and another and another.
Start doing the things you think should be done, and start being what you think society should become. Do you believe in free speech? Then speak freely. Do you love the truth? Then tell it. Do you believe in an open society? Then act in the open. Do you believe in a decent and humane society? Then behave decently and humanely.
If you have only one smile in you, give it to the people you love. Don't be surly at home, then go out in the street and start grinning 'Good morning' at total strangers.
