There is one important negative aspect of the truth of suffering and indeed of all the four truths. A view of human life which is common in Christian and Mohammedan countries represents man as put in the world by God, and human life as a service to be rendered to God. Whether it is pleasant, worth living or not are hardly questions for God's servants. There is no trace of such a view in the Buddha's teaching. It is throughout assumed that man in judging human life by human standards is not presumptuous or blind to higher issues. Life involves unhappiness: that is a fact, a cardinal truth. That this unhappiness may be ordered for disciplinary or other mysterious motives by what is vaguely called One above, that it would disappear or be explained if we could contemplate our world as forming part of a larger universe, that "there is some far off divine event," some unexpected solution in the fifth act of this complicated tragedy, which could justify the creator of this dukkhakkhandha, this mass of unhappiness—for all such ideas the doctrine of the Blessed One has nothing but silence, the courteous and charitable silence which will not speak contemptuously. The world of transmigration has neither beginning nor end nor meaning: to those who wish to escape from it the Buddha can show the way: of obligation to stop in it there can be no question[441].
Buddhism is often described as pessimistic, but is the epithet just? What does it mean? The dictionary defines pessimism as the doctrine which teaches that the world is as bad as it can be and that everything naturally tends towards evil. That is emphatically not Buddhist teaching. The higher forms of religion have their basis and origin in the existence of evil, but their justification and value depend on their power to remove it. A religion, therefore, can never be pessimistic, just as a doctor who should simply pronounce diseases to be incurable would never be successful as a practitioner. The Buddha states with the utmost frankness that religion is dependent on the existence of evil. "If three things did not exist, the Buddha would not appear in the world and his law and doctrine would not shine. What are the three? Birth, old age and death." This is true. If there were people leading perfectly happy, untroubled lives, it is not likely that any thought of religion would enter their minds, and their irreligious attitude would be reasonable, for the most that any deity is asked to give is perfect happiness, and that these imaginary folk are supposed to have already. But according to Buddhism no form of existence can be perfectly happy or permanent. Gods and angels may be happier than men but they are not free from the tyranny of desire and ultimately they must fall from their high estate and pass away.

The second Truth declares the origin of suffering. "It is," says the Buddha, "the thirst which causes rebirth, which is accompanied by pleasure and lust and takes delight now here, now there; namely, the thirst for pleasure, the thirst for another life, the thirst for success." This Thirst (Taṇhâ) is the craving for life in the widest sense: the craving for pleasure which propagates life, the craving for existence in the dying man which brings about another birth, the craving for wealth, for power, for pre-eminence within the limits of the present life. What is the nature of this craving and of its action? Before attempting to answer we must consider what is known as the chain of causation[442], one of the oldest, most celebrated, and most obscure formulæ of Buddhism. It is stated that the Buddha knew it before attaining enlightenment[443], but it is second in importance only to the four truths, and in the opening sections of the Mahâvagga, he is represented as meditating on it under the Bo-tree, both in its positive and negative form. It runs as follows: "From ignorance come the sankhâras, from the sankhâras comes consciousness, from consciousness come name-and-form, from name-and-form come the six provinces (of the senses), from the six provinces comes contact, from contact comes sensation, from sensation comes craving, from craving comes clinging, from clinging comes existence, from existence comes birth, from birth come old age and death, pain and lamentation, suffering, sorrow, and despair. This is the origin of this whole mass of suffering. But by the destruction of ignorance, effected by the complete absence of lust, the sankhâras are destroyed, by the destruction of the sankhâras, consciousness is destroyed" and so on through the whole chain backwards.
The chain is also known as the twelve Nidânas or causes. It is clearly in its positive and negative forms an amplification of the second and third truths respectively, or perhaps they are a luminous compendium of it.
Besides the full form quoted above there are shorter versions. Sometimes there are only nine links[444] or there are five links combined in an endless chain[445]. So we must not attach too much importance to the number or order of links. The chain is not a genealogy but a statement respecting the interdependence of certain stages and aspects of human nature. And though the importance of cause (hetu) is often emphasized, the causal relation is understood in a wider sense than is usual in our idiom. If there were no birth, there would be no death, but though birth and death are interdependent we should hardly say that birth is the cause of death.
In whatever way we take the Chain of Causation, it seems to bring a being into existence twice, and this is the view of Buddhaghosa who says that the first two links (ignorance and the sankhâras) belong to past time and explain the present existence: the next eight (consciousness to existence) analyse the present existence: and the last two (birth and old age) belong to future time, representing the results in another existence of desire felt in this existence. And that is perhaps what the constructor of the formula meant. It is clearest if taken backwards. Suppose, the Buddha once said to Ânanda[446], there were no birth, would there then be any old age or death? Clearly not. That is the meaning of saying that old age and death depend on birth: if birth were annihilated, they too would be annihilated. Similarly birth depends on Bhava which means becoming and does not imply anything self-existent and stationary: all the world is a continual process of coming into existence and passing away. It is on the universality of this process that birth (jâti) depends. But on what does the endless becoming itself depend? We seem here on the threshold of the deepest problems but the answer, though of wide consequences, brings us back to the strictly human and didactic sphere. Existence depends on Upâdâna. This word means literally grasping or clinging to and should be so translated here but it also means fuel and its use is coloured by this meaning, since Buddhist metaphor is fond of describing life as a flame. Existence cannot continue without the clinging to life, just as fire cannot continue without fuel[447].
The clinging in its turn depends on Taṇhâ, the thirst or craving for existence. The distinction between taṇhâ and upâdâna is not always observed, and it is often said taṇhâ is the cause of karma or of sorrow. But, strictly speaking, upâdâna is the grasping at life or pleasure: taṇhâ is the incessant, unsatisfied craving which causes it. It is compared to the birana, a weed which infests rice fields and sends its roots deep into the ground. So long as the smallest piece of root is left the weed springs up again and propagates itself with surprising rapidity, though the cultivator thought he had exterminated it. This metaphor is also used to illustrate how taṇhâ leads to a new birth. Death is like cutting down the plant: the root remains and sends up another growth.
We now seem to have reached an ultimate principle and basis, namely, the craving for life which transcends the limits of one existence and finds expression in birth after birth. Many passages in the Pitakas justify the idea that the force which constructs the universe of our experience is an impersonal appetite, analogous to the Will of Schopenhauer. The shorter formula quoted above in which it is said that the
