those which start from the recognition of external facts, and therefore the control and right direction of these inner perceptions is a matter of the first moment.

The faculties most immediately concerned are the intuition and the imagination, but it is at first difficult to see how the intuition, which is entirely spontaneous, can be brought under the control of the will. Of course, the spontaneousness of the intuition cannot in any way be interfered with, for if it ceased to act spontaneously it would cease to be the intuition. Its province is, as it were, to capture ideas from the infinite and present them to the mind to be dealt with at its discretion. In our mental constitution the intuition is the point of origination and, therefore, for it to cease to act spontaneously would be for it to cease to act at all. But the experience of a long succession of observers shows that the intuition can be trained so as to acquire increased sensitiveness in some particular direction, and the choice of the general direction is determined by the will of the individual.

It will be found that the intuition works most readily in respect to those subjects which most habitually occupy our thought; and according to the physiological correspondences which we have been considering this might be accounted for on the physical plane by the formation of brain-channels specially adapted for the induction in the molecular system of vibrations
