One-third, more or less, of all the sorrow . . . [we] must endure is . . . inherent in the human condition, the price we must pay for being sentient and self-conscious organisms, aspirants to liberation, but subject to the laws of nature and under orders to keep on marching, through irreversible time . . . toward decrepitude and the certainty of death. The remaining two-thirds of all sorrow is homemade and, so far as the universe is concerned, unnecessary.
Perhaps the whole root of our trouble, the human trouble, is that we will sacrifice all the beauty of our lives, will imprison ourselves in totems, taboos, crosses, blood sacrifices, steeples, mosques, races, armies, flags, nations, in order to deny the fact of death, the only fact we have.
