Whereas introverted sensation is mainly confined to the perception of particular innervation phenomena by way of the unconscious, and does not go beyond them, intuition represses this side of the subjective factor and perceives the image which has really occasioned the innervation. Supposing, for instance, a man is overtaken by a psychogenic attack of giddiness. Sensation is arrested by the peculiar character of this innervation-disturbance, perceiving all its qualities, its intensity, its transient course, the nature of its origin and disappearance in their every detail, without raising the smallest inquiry concerning the nature of the thing which produced the disturbance, or advancing anything as to its content. Intuition, on the other hand, receives from the sensation only the impetus to immediate activity; it peers behind the scenes, quickly perceiving the inner image that gave rise to the specific phenomenon, the attack of vertigo, in the present case. It sees the image of a tottering man pierced through the heart by an arrow. This image fascinates the intuitive activity
; it is arrested by it, and seeks to explore every detail of it. It holds fast to the vision, observing with the liveliest interest how the picture changes, unfolds further, and finally fades. In this way introverted intuition perceives all the background processes of consciousness with almost the same distinctness as extraverted sensation senses outer objects.
For intuition, therefore, the unconscious images attain to the dignity of things or objects.
