 Condillac, however, thinks animals are less inventive than humans because they have fewer needs and also “fewer means to multiply their own ideas and make combinations of all sort” (Treatise of Animals, II.2). In different words, animals are more easily satisfied with their lot and they are less intelligent. Contrary to what many authors say, animals of the same species do not do the same things because they imitate each other. Rather, they all end up doing the same things, because they have the same needs and the same organs perfectly suited to the satisfaction of those needs. Thus, each animal acquires the same habits as any other animal of the same species, whether placed alone or in company. Paradoxically, humans end up being different from each other precisely because they are the only animals that imitate each other. There is relatively little communication of ideas by way of language among animals: their needs are more limited and therefore they do not need to learn from each other as much as humans do. Humans, on the contrary, desire to learn from each other more and so imitate each other. As they communicate more with each other, they also discover the differences in their talents and interests and put them to use for themselves and others (Treatise of Animals II.3). Animals keep to their subsistence economy, while humans develop a system of division of labour in order to satisfy their needs: one might start by trying to be a skilled hunter like his neighbour only to discover that he had better leave hunting to his neighbor and concentrate on the manufacture of bows and arrows. Since, individuals are often placed in different circumstances requiring different solutions, new needs emerge. As new needs emerge, useful discoveries are made and social ties get stronger. Just like in the Essay, the intertwined factors of language and social intercourse make humans superior to animals in their capacities.
