But if we take the other alternative, and suppose an unconscious mental mechanism, we cannot legitimately conceive of the process going on in this as other than what prevails in all mental mechanism, namely, than as by way of idea and will. We are, therefore, compelled to imagine a causal connection between the consciously recognised motive and the will to do the instinctive action, through unconscious idea and will; nor do I know how this connection can be conceived as being brought about more simply than through a conceived and willed purpose. {102b} Arrived at this point, however, we have attained the logical mechanism peculiar to and inseparable from all mind, and find unconscious purpose to be an indispensable link in every instinctive action. With this, therefore, the conception of a mental mechanism, dead and predestined from without, has disappeared, and has become transformed into the spiritual life inseparable from logic, so that we have reached the sole remaining requirement for the conception of an actual instinct, which proves to be a conscious willing of the means towards an unconsciously willed purpose. This conception explains clearly and without violence all the problems which instinct presents to us; or more truly, all that was problematical about instinct disappears when its true nature has been thus declared. If this work were confined to the consideration of instinct alone, the conception of an unconscious activity of mind might excite opposition, inasmuch as it is one with which our educated public is not yet familiar; but in a work like the present, every chapter of which adduces fresh facts in support of the existence of such an activity and of its remarkable consequences, the novelty of the theory should be taken no farther into consideration.
