tendency of all animals and men to retain life and carry it on as long as possible – a tendency which was set forth above as characteristic of the subjective, or of the will – it is necessary to make clear to ourselves that this is by no means the result of any objective knowledge of the worth of life, but is independent of all knowledge; or, in other words, that those beings exhibit themselves, not as drawn from in front, but as impelled from behind.
If with this intention we first of all review the interminable series of animals, consider the infinite variety of their forms, as they exhibit themselves always differently modified according to their element and manner of life, and also ponder the inimitable ingenuity of their structure and mechanism, which is carried out with equal perfection in every individual; and finally, if we take into consideration the incredible expenditure of strength, dexterity, prudence, and activity which every animal has ceaselessly to make through its whole life; if, approaching the matter more closely, we contemplate the untiring diligence of wretched little ants, the marvellous and ingenious industry of the bees, or observe how a single burying-beetle (Necrophorus vespillo) buries a mole of forty times its own size in two days in order to deposit its eggs in it and insure nourishment for the future brood (Gleditsch, Physik. Bot. Œkon. Abhandl., iii. 220), at the same time calling to mind how the life of most insects is nothing but ceaseless labour to prepare food and an abode for the future brood which will arise from their eggs, and which then, after they have consumed the food and passed through the chrysalis state, enter upon life merely to begin again from the beginning the same labour; then also how, like this, the life of the birds is for the most part taken up with their distant and laborious migrations, then with the building of their nests and the collecting of food for the brood, which itself has to play the same rôle the following year; and so all work constantly for the future, which afterwards makes bankrupt; – then we cannot avoid looking round for the reward
