4. We have, however, still to examine what is called the affective phase of the Soul. This has, no doubt, been touched upon above where we dealt with the passions in general as grouped about the initiative phase of the Soul and the desiring faculty in its effort to shape things to its choice: but more is required; we must begin by forming a clear idea of what is meant by this affective faculty of the Soul.
In general terms it means the centre about which we recognize the affections to be grouped; and by affections we mean those states upon which follow pleasure and pain.
Now among these affections we must distinguish. Some are pivoted upon judgements; thus, a Man judging his death to be at hand may feel fear; foreseeing some fortunate turn of events, he is happy: the opinion lies in one sphere; the affection is stirred in another. Sometimes the affections take the lead and automatically bring in the notion which thus becomes present to the appropriate faculty: but as we have explained, an act of opinion does not introduce any change into the Soul or Mind: what happens is that from the notion of some impending evil is produced the quite separate thing, fear, and this fear, in turn, becomes known in that part of the Mind which is said under such circumstances to harbour fear.
But what is the action of this fear upon the Mind?
The general answer is that it sets up trouble and confusion before an evil anticipated. It should, however, be quite clear that the Soul or Mind is the seat of all imaginative representation- both the higher representation known as opinion or judgement and the lower representation which is not so much a judgement as a vague notion unattended by discrimination, something resembling the action by which, as is believed, the "Nature" of common speech produces, unconsciously, the objects of the partial sphere. It is equally certain that in all that follows upon the mental act or state, the disturbance, confined to the body, belongs to the sense-order; trembling, pallor, inability to speak, have obviously nothing to do with the spiritual portion of the being. The Soul, in fact, would have to be described as corporeal if it were the seat of such symptoms: besides, in that case the trouble would not even reach the body since the only transmitting principle, oppressed by sensation, jarred out of itself, would be inhibited.
None the less, there is an affective phase of the Soul or Mind and this is not corporeal; it can be, only, some kind of Ideal-form.
Now Matter is the one field of the desiring faculty, as of the principles of nutrition growth and engendering, which are root and spring to desire and to every other affection known to this Ideal-form. No Ideal-form can be the victim of disturbance or be in any way affected: it remains in tranquillity; only the Matter associated with it can be affected by any state or experience induced by the movement which its mere presence suffices to set up. Thus the vegetal Principle induces vegetal life but it does not, itself, pass through the processes of vegetation; it gives growth but it does not grow; in no movement which it originates is it moved with the motion it induces; it is in perfect repose, or, at least, its movement, really its act, is utterly different from what it causes elsewhere.
The nature of an Ideal-form is to be, of itself, an activity; it operates by its mere presence: it is as if Melody itself plucked the strings. The affective phase of the Soul or Mind will be the operative cause of all affection; it originates the movement either under the stimulus of some sense-presentment or independently- and it is a question to be examined whether the judgement leading to the movement operates from above or not- but the affective phase itself remains unmoved like Melody dictating music. The causes originating the movement may be likened to the musician; what is moved is like the strings of his instrument, and once more, the Melodic Principle itself is not affected, but only the strings, though, however much the musician desired it, he could not pluck the strings except under dictation from the principle of Melody.
