The animals live in society but are not conscious of it. The degree of social awareness is extremely dim. They lack the ability to perceive logical relations between things and the power of integrating (not merely associating) various order of things through mental synthesis. Of course, it may be said that bees show a remarkable degree of organization and therefore, intelligence in building their hexagonal cells for storing honey or that the birds evince a high degree of understanding in building their nest, singing their songs, and protecting themselves against the huntsmen, yet nobody would grant to bees, birds, or animals more intelligence than to man. Their division of labor is not learned, it is based upon biological specialization. Their societies are the sole result of biological evolution, rather than social evolution. The way in which animals perform their work is quasi-mechanical and stereo-typed whereas the work of man, even if it is inferior, is done with forethought and understanding.
