Obviously, unconscious life cannot be clearly defined. We can only guess at its nature from the angle at which its processes enter consciousness, from its disruptive action upon our systems of thought, and from what we can remember of its manifestations in dreams. We know that our emotions rise from it like bubbles through water, that it determines our motives and our interests, and that it is not homogeneous by conscious standards. Its interferences with our conscious life are always spontaneous and strongly charged with feeling. We can infer from such interferences that it has purposes. From its manifestations in dreams and trance states we know that it has access to knowledge by other than conscious means. This kind of knowledge, when it makes its way into consciousness, we sometimes recognise by its emotional force and unexpectedness, and call it intuition. But for the most part we serve the purposes of our unconscious without knowing that we do so, and admit its wisdom only through the indirect channels of conscious rationalisation. The processes of the unconscious can, however, be roughly described by contrast with the conscious life. The unconscious is concerned with growth rather than form; it is essentially emotional, spontaneous, and irrational. As far as we know, it is concrete in its thinking and not abstract; it creates living agents and not systems of thought. Thus, while conscious processes supply form and permanence in our world, unconscious processes supply growing vitality and change. The creations of unconscious life are wrought in mortal substances, those of conscious life in enduring patterns which are one step removed from life. Unconscious life creates, for example, human beings: conscious life creates, for example, philosophy. If men are stronger in conscious life, and women in unconscious life, their creative powers must express their strength. Men should excel in translating life into conscious forms, women in fostering the growth of life itself. Men will create systems of philosophy or government, while women are creating individual human beings. IV
