Footnote 78: The value of subconscious personalities for this purpose has been overlooked, owing, I suppose, to such conditions being unusual and bizarre, and the assumption that they have little in common with ordinary subconscious processes. But it ought to be obvious that _in principle_ it makes little difference whether a subconscious system is constellated into a large self-conscious system called a personality, or whether it is restricted to a system limited to a few particular coconscious ideas. In the former case the possibilities of its interfering with the personal consciousness may be more extended and more influential, that is all. Footnote 79: Of course, from a practical (clinical) point of view, it is of no consequence whether given phenomena are induced by coconscious or unconscious processes; the individual is not aware of either. Let me answer, however, a strange objection that has been made to such an inquiry. It has been objected that as it makes no practical difference whether the subconscious process, which induces a given phenomenon, is coconscious or unconscious, and as in many given cases it is difficult or impossible to determine the question, therefore, that such inquiries are useless. Plainly such an objection only concerns applied science, not science itself. It concerns only the practicing physician who deals solely with reactions. Likewise it makes no difference to the practicing chemist whether some atoms are positive and some negative ions, and whether on further analysis they are systems of electrons, and whether, again, electrons are points of electricity. The practical chemist deals only with reactions. Such questions, however, having to do with the ultimate nature of matter are of the highest interest to science. Likewise the nature of subconscious processes is of the highest interest to psychological science. Footnote 80: I have passed over the classical hysterical phenomena as they open a very large subject which needs a special treatment by itself. The subconscious processes underlying them, so far as they have been determined, are, as I have explained, admittedly coconscious, though some may be in part unconscious. They are too complicated to be entered into here. Footnote 81:
