has arrived in its vicinity he absolutely will not go any further, but turns hastily back, seized with anxiety he knows not why; – the magazine blows up. A third upon the ocean feels moved one night, without any reason, not to undress, but lays himself on the bed in his clothes and boots, and even with his spectacles on; – in the night the ship goes on fire, and he is among the few who save themselves in the boat. All this depends upon the dull after-effect of forgotten fatidical dreams, and gives us the key to an analogous understanding of instinct and mechanical tendencies.
On the other hand, as has been said, the mechanical tendencies of insects reflect much light upon the working of the unconscious will in the inner functions of the organism and in its construction. For without any difficulty we can see in the ant-hill or the beehive the picture of an organism explained and brought to the light of knowledge. In this sense Burdach says (Physiologie, vol. ii. p. 22): "The formation and depositing of the eggs is the part of the queen-bee, and the care for the cultivation of them falls to the workers; thus in the former the ovary, and in the latter the uterus, is individualised." In the insect society, as in the animal organism, the vita propria of each part is subordinated to the life of the whole, and the care for the whole precedes that for particular existence; indeed the latter is only conditionally willed, the former unconditionally; therefore the individuals are even sacrificed occasionally for the whole, as we allow a limb to be taken off in order to save the whole body. Thus, for example, if the path is closed by water against the march of the ants, those in front boldly throw themselves in until their corpses are heaped up into a dam for those that follow. When the drones have become useless they are stung to death. Two queens in the hive are surrounded, and must fight with each other till one of them loses its life. The ant-mother bites its own wings off after it has been impregnated, for they would only be a hindrance
