 the eventualities it seeks with those it flies from; and tendency, no less than movement, needs an organised medium to make it possible, while aspiration and fear involve an ideal world. Yet a principle of choice is not deducible from mere ideas, and no interest is involved in the formal relations of things. All survey needs an arbitrary starting-point; all valuation rests on an irrational bias. The absolute flux cannot be physically arrested; but what arrests it ideally is the fixing of some point in it from which it can be measured and illumined. Otherwise it could show no form and maintain no preference; it would be impossible to approach or recede from a represented state, and to suffer or to exert will in view of events. The irrational fate that lodges the transcendental self in this or that body, inspires it with definite passions, and subjects it to particular buffets from the outer world—this is the prime condition of all observation and inference, of all failure or success.

Those sensations in which a transition is contained need only analysis to yield two ideal and related terms—two points in space or two characters in feeling. Hot and cold, here and there, good and bad, now and then, are dyads that spring into being when the flux accentuates some term and so makes possible a discrimination of parts and directions in its own movement. An initial attitude sustains incipient interests. What we first discover in ourselves,
