Thus, for the third time, but now on a higher plane, that of intelligence and rationality, is traced the process of development or realisation by which reason becomes reasoned knowledge and rational will, a free or autonomous intelligence. And, as before, the starting-point, alike in theoretical and practical mind, is feeling—or immediate knowledge and immediate sense of Ought. The basis of thought is an immediate perception—a sensuous affection or given something, and the basis of the idea of a general satisfaction is the natural claim to determine the outward existence conformably to individual feeling. In intelligent perception or intuition the important factor is attention, which raises it above mere passive acceptance and awareness of a given fact. Attention thus involves on one hand the externality of its object, and on the other affirms its dependence on the act of the subject: it sets the objects before and out of itself, in space and time, but yet in so doing it shows itself master of the objects. If perception presuppose attention, in short, they cease to be wholly outward: we make them ours, and the space and time they fill are projected by us. So attended to, they are appropriated, inwardised and recollected: they take their place in a mental place and mental time: they receive a general or de-individualised character in the memory-image. These are retained as mental property, but retained actually only in so far they are revivable and revived. Such revival is the work of imagination working by the so-called laws of association. But the possession of its ideas thus inwardised and recollected by the mind is largely a matter of chance. The mind is not really fully master of them until it has been able to give them a certain objectivity, by replacing the mental image by a vocal, i.e. a sensible sign. By means of words, intelligence turns its ideas or representations into quasi-realities: it creates a sort of superior sense-world, the world of language, where ideas live a potential, which is also an actual, life. Words are sensibles, but they are sensibles which completely lose themselves in their meaning. As sensibles, they render possible that verbal memory which is the handmaid of thought: but which also as merely mechanical can leave thought altogether out of account. It is through words that thought is made possible: for it alone permits the movement through ideas without being distracted through a multitude of associations. In them thought has an instrument completely at its own level, but still only a machine, and in memory the working of that machine. We think in names, not in general images, but in terms which only serve as vehicles for mental synthesis and analysis.
