Occurrences in this domain are beyond the reach of exact prediction because of the variety of factors in operation, not because of any lack of order in nature.
We can reject everything else: religion, ideology, all received wisdom. But we cannot escape the necessity of love and compassion. This, then, is my true religion, my simple faith. In this sense, there is no need for temple or church, for mosque or synagogue, no need for complicated philosophy, doctrine, or dogma. Our own heart, our own mind, is the temple. The doctrine is compassion. Love for others and respect for their rights and dignity, no matter who or what they are: ultimately these are all we need.
Strictly speaking, one cannot legislate love, but what one can do is legislate fairness and justice. If legislation does not prohibit our living side by side, sooner or later your child will fall on the pavement and I'll be the one to pick her up. Or one of my children will not be able to get into the house and you'll have to say, "Stop here until your mom comes here." Legislation affords us the chance to see if we might love each other.
If you will take me for your wife, Walter, I will love you dearly. If you will let me go with you, Walter, I will go to the world's end without fear. I can give up nothing for you - I have nothing to resign, and no one to forsake; but all my love and life shall be devoted to you, and with my last breath I will breathe your name to God if I have sense and memory left.
