The so-called _laws of the association of ideas_ were objects of great interest, especially during that outburst of empirical psychology which was contemporaneous with the decline of philosophy. In the first place, it is not _Ideas_ (properly so called) which are associated. Secondly, these modes of relation are not _laws_, just for the reason that there are so many laws about the same thing, as to suggest a caprice and a contingency opposed to the very nature of law. It is a matter of chance whether the link of association is something pictorial, or an intellectual category, such as likeness and contrast, reason and consequence. The train of images and representations suggested by association is the sport of vacant-minded ideation, where, though intelligence shows itself by a certain formal universality, the matter is entirely pictorial.—Image and idea, if we leave out of account the more precise definition of those forms given above, present also a distinction in content. The former is the more consciously-concrete idea, whereas the idea (representation), whatever be its content (from image, notion, or idea), has always the peculiarity, though belonging to intelligence, of being in respect of its content given and immediate. It is still true of this idea or representation, as of all intelligence, that it finds its material, as a matter of fact, to _be_ so and so; and the universality which the aforesaid material receives by ideation is still abstract. Mental representation is the mean in the syllogism of the elevation of intelligence, the link between the two significations of self-relatedness—viz. _being_ and _universality_, which in consciousness receive the title of object and subject. Intelligence complements what is merely found by the attribution of universality, and the internal and its own by the attribution of being, but a being of its own institution. (On the distinction of representations and thoughts, see Introd. to the Logic, § 20 note.) Abstraction, which occurs in the ideational activity by which general ideas are produced (and ideas _quâ_ ideas virtually have the form of generality), is frequently explained as the incidence of many similar images one upon another and is supposed to be thus made intelligible. If this super-imposing is to be no mere accident and without principle, a force of attraction in like images must be assumed, or something of the sort, which at the same time would have the negative power of rubbing off the dissimilar elements against each other. This force is really intelligence itself,—the self-identical ego which by its internalising recollection gives the images _ipso facto_ generality, and subsumes the single intuition under the already internalised image (§ 453).
