A famous author, reckoning up the good and evil of human life, and comparing the aggregates, finds that our pains greatly exceed our pleasures: so that, all things considered, human life is not at all a valuable gift. This conclusion does not surprise me; for the writer drew all his arguments from man in civilisation. Had he gone back to the state of nature, his inquiries would clearly have had a different result, and man would have been seen to be subject to very few evils not of his own creation. It has indeed cost us not a little trouble to make ourselves as wretched as we are. When we consider, on the one hand, the immense labours of mankind, the many sciences brought to perfection, the arts invented, the powers employed, the deeps filled up, the mountains levelled, the rocks shattered, the rivers made navigable, the tracts of land cleared, the lakes emptied, the marshes drained, the enormous structures erected on land, and the teeming vessels that cover the sea; and, on the other hand, estimate with ever so little thought, the real advantages that have accrued from all these works to mankind, we cannot help being amazed at the vast disproportion there is between these things, and deploring the infatuation of man, which, to gratify his silly pride and vain self-admiration, induces him eagerly to pursue all the miseries he is capable of feeling, though beneficent nature had kindly placed them out of his way. That men are actually wicked, a sad and continual experience of them proves beyond doubt: but all the same, I think I've shown that man is naturally good. What then can have depraved him to such an extent, except the changes that have happened in his constitution, the advances he has made, and the knowledge he has acquired? We may admire human society as much as we please; it will be none the less true that it necessarily leads men to hate each other in proportion as their interests clash, and to do one another apparent services, while they are really doing every imaginable mischief. What can be thought of a relation, in which the interest of every individual dictates rules directly opposite to those the public reason dictates to the community in general--in which every man finds his profit in the misfortunes of his neighbour? There is not perhaps any man in a comfortable position who has not greedy heirs, and perhaps even children, secretly wishing for his death; not a ship at sea, of which the loss would not be good news to some merchant or other; not a house, which some debtor of bad faith would not be glad to see reduced to ashes with all the papers it contains; not a nation which does not rejoice at the disasters that befall its neighbours. Thus it is that we find our advantage in the misfortunes of our fellow-creatures, and that the loss of one man almost always constitutes the prosperity of another. But it is still more pernicious that public calamities are the objects of the hopes and expectations of innumerable individuals.
