Dialogues Concerning Natural Religion

by David Hume

If every thing in the universe be conducted by general laws, and if animals be rendered susceptible of pain, it scarcely seems possible but some ill must arise in the various shocks of matter, and the various concurrence and opposition of general laws; but this ill would be very rare, were it not for the third circumstance, which I proposed to mention, viz. the great frugality with which all powers and faculties are distributed to every particular being. So well adjusted are the organs and capacities of all animals, and so well fitted to their preservation, that, as far as history or tradition reaches, there appears not to be any single species which has yet been extinguished in the universe. Every animal has the requisite endowments; but these endowments are bestowed with so scrupulous an economy, that any considerable diminution must entirely destroy the creature. Wherever one power is increased, there is a proportional abatement in the others. Animals which excel in swiftness are commonly defective in force. Those which possess both are either imperfect in some of their senses, or are oppressed with the most craving wants. The human species, whose chief excellency is reason and sagacity, is of all others the most necessitous, and the most deficient in bodily advantages; without clothes, without arms, without food, without lodging, without any convenience of life, except what they owe to their own skill and industry. In short, nature seems to have formed an exact calculation of the necessities of her creatures; and, like a rigid master, has afforded them little more powers or endowments than what are strictly sufficient to supply those necessities. An indulgent parent would have bestowed a large stock, in order to guard against accidents, and secure the happiness and welfare of the creature in the most unfortunate concurrence of circumstances. Every course of life would not have been so surrounded with precipices, that the least departure from the true path, by mistake or necessity, must involve us in misery and ruin. Some reserve, some fund, would have been provided to ensure happiness; nor would the powers and the necessities have been adjusted with so rigid an economy. The Author of Nature is inconceivably powerful: his force is supposed great, if not altogether inexhaustible: nor is there any reason, as far as we can judge, to make him observe this strict frugality in his dealings with his creatures. It would have been better, were his power extremely limited, to have created fewer animals, and to have endowed these with more faculties for their happiness and preservation. A builder is never esteemed prudent, who undertakes a plan beyond what his stock will enable him to finish.

In order to cure most of the ills of human life, I require not that man should have the wings of the eagle, the swiftness of the stag, the force of the ox, the arms of the lion, the scales of the crocodile or rhinoceros; much less do I demand the sagacity of an angel or cherubim. I am contented to take an increase in one single power or faculty of his soul. Let him be endowed with a greater propensity to industry and labour; a more vigorous spring and activity of mind; a more constant bent to business and application. Let the whole species possess naturally an equal diligence with that which many individuals are able to attain by habit and reflection; and the most beneficial consequences, without any allay of ill, is the immediate and necessary result of this endowment. Almost all the moral, as well as natural evils of human life, arise from idleness; and were our species, by the original constitution of their frame, exempt from this vice or infirmity, the perfect cultivation of land, the improvement of arts and manufactures, the exact execution of every office and duty, immediately follow; and men at once may fully reach that state of society, which is so imperfectly attained by the best regulated government. But as industry is a power, and the most valuable of any, Nature seems determined, suitably to her usual maxims, to bestow it on men with a very sparing hand; and rather to punish him severely for his deficiency in it, than to reward him for his attainments. She has so contrived his frame, that nothing but the most violent necessity can oblige him to labour; and she employs all his other wants to overcome, at least in part, the want of diligence, and to endow him with some share of a faculty of which she has thought fit naturally to bereave him. Here our demands may be allowed very humble, and therefore the more reasonable. If we required the endowments of superior penetration and judgement, of a more delicate taste of beauty, of a nicer sensibility to benevolence and friendship; we might be told, that we impiously pretend to break the order of Nature; that we want to exalt ourselves into a higher rank of being; that the presents which we require, not being suitable to our state and condition, would only be pernicious to us. But it is hard; I dare to repeat it, it is hard, that being placed in a world so full of wants and necessities, where almost every being and element is either our foe or refuses its assistance ... we should also have our own temper to struggle with, and should be deprived of that faculty which can alone fence against these multiplied evils.

The fourth circumstance, whence arises the misery and ill of the universe, is the inaccurate workmanship of all the springs and principles of the great machine of nature. It must be acknowledged, that there are few parts of the universe, which seem not to serve some purpose, and whose removal would not produce a visible defect and disorder in the whole. The parts hang all together; nor can one be touched without affecting the rest, in a greater or less degree. But at the same time, it must be observed, that none of these parts or principles, however useful, are so accurately adjusted, as to keep precisely within those bounds in which their utility consists; but they are, all of them, apt, on every occasion, to run into the one extreme or the other. One would imagine, that this grand production had not received the last hand of the maker; so little finished is every part, and so coarse are the strokes with which it is executed. Thus, the winds are requisite to convey the vapours along the surface of the globe, and to assist men in navigation: but how oft, rising up to tempests and hurricanes, do they become pernicious? Rains are necessary to nourish all the plants and animals of the earth: but how often are they defective? how often excessive? Heat is requisite to all life and vegetation; but is not always found in the due proportion. On the mixture and secretion of the humours and juices of the body depend the health and prosperity of the animal: but the parts perform not regularly their proper function. What more useful than all the passions of the mind, ambition, vanity, love, anger? But how oft do they break their bounds, and cause the greatest convulsions in society? There is nothing so advantageous in the universe, but what frequently becomes pernicious, by its excess or defect; nor has Nature guarded, with the requisite accuracy, against all disorder or confusion. The irregularity is never perhaps so great as to destroy any species; but is often sufficient to involve the individuals in ruin and misery.

On the concurrence, then, of these four circumstances, does all or the greatest part of natural evil depend. Were all living creatures incapable of pain, or were the world administered by particular volitions, evil never could have found access into the universe: and were animals endowed with a large stock of powers and faculties, beyond what strict necessity requires; or were the several springs and principles of the universe so accurately framed as to preserve always the just temperament and medium; there must have been very little ill in comparison of what we feel at present. What then shall we pronounce on this occasion? Shall we say that these circumstances are not necessary, and that they might easily have been altered in the contrivance of the universe? This decision seems too presumptuous for creatures so blind and ignorant. Let us be more modest in our conclusions. Let us allow, that, if the goodness of the Deity (I mean a goodness like the human) could be established on any tolerable reasons a priori, these phenomena, however untoward, would not be sufficient to subvert that principle; but might easily, in some unknown manner, be reconcilable to it. But let us still assert, that as this goodness is not antecedently established, but must be inferred from the phenomena, there can be no grounds for such an inference, while there are so many ills in the universe, and while these ills might so easily have been remedied, as far as human understanding can be allowed to judge on such a subject. I am Sceptic enough to allow, that the bad appearances, notwithstanding all my reasonings, may be compatible with such attributes as you suppose; but surely they can never prove these attributes. Such a conclusion cannot result from Scepticism, but must arise from the phenomena, and from our confidence in the reasonings which we deduce from these phenomena.

Look round this universe. What an immense profusion of beings, animated and organised, sensible and active! You admire this prodigious variety and fecundity. But inspect a little more narrowly these living existences, the only beings worth regarding. How hostile and destructive to each other! How insufficient all of them for their own happiness! How contemptible or odious to the spectator! The whole presents nothing but the idea of a blind Nature, impregnated by a great vivifying principle, and pouring forth from her lap, without discernment or parental care, her maimed and abortive children!

Here the MANICHAEAN system occurs as a proper hypothesis to solve the difficulty: and no doubt, in some respects, it is very specious, and has more probability than the common hypothesis, by giving a plausible account of the strange mixture of good and ill which appears in life. But if we consider, on the other hand, the perfect uniformity and agreement of the parts of the universe, we shall not discover in it any marks of the combat of a malevolent with a benevolent being. There is indeed an opposition of pains and pleasures in the feelings of sensible creatures: but are not all the operations of Nature carried on by an opposition of principles, of hot and cold, moist and dry, light and heavy? The true conclusion is, that the original Source of all things is entirely indifferent to all these principles; and has no more regard to good above ill, than to heat above cold, or to drought above moisture, or to light above heavy.

There may four hypotheses be framed concerning the first causes of the universe: that they are endowed with perfect goodness; that they have perfect malice; that they are opposite, and have both goodness and malice; that they have neither goodness nor malice. Mixed phenomena can never prove the two former unmixed principles; and the uniformity and steadiness of general laws seem to oppose the third. The fourth, therefore, seems by far the most probable.

What I have said concerning natural evil will apply to moral, with little or no variation; and we have no more reason to infer, that the rectitude of the Supreme Being resembles human rectitude, than that his benevolence resembles the human. Nay, it will be thought, that we have still greater cause to exclude from him moral sentiments, such as we feel them; since moral evil, in the opinion of many, is much more predominant above moral good than natural evil above natural good.

But even though this should not be allowed, and though the virtue which is in mankind should be acknowledged much superior to the vice, yet so long as there is any vice at all in the universe, it will very much puzzle you Anthropomorphites, how to account for it. You must assign a cause for it, without having recourse to the first cause. But as every effect must have a cause, and that cause another, you must either carry on the progression in infinitum, or rest on that original principle, who is the ultimate cause of all things...

Hold! hold! cried DEMEA: Whither does your imagination hurry you? I joined in alliance with you, in order to prove the incomprehensible nature of the Divine Being, and refute the principles of CLEANTHES, who would measure every thing by human rule and standard. But I now find you running into all the topics of the greatest libertines and infidels, and betraying that holy cause which you seemingly espoused. Are you secretly, then, a more dangerous enemy than CLEANTHES himself?
