We are sustained in this great quest for happiness, it seems to me, by hope. As an old Tibetan proverb puts it, The next life or tomorrow - we can never be certain which will come first. But we hope to go on living. We hope that through this or that action we can bring about happiness.
We find modern living organised so that it demands the least possible direct dependence on others...This in turn encourages us to suppose that because others are not important for my happiness, their happiness is not important to me.
