39. The same paralogism appears under a slightly altered form when it is stated (in the first letter to Stillingfleet) that the idea of substance as the ‘general indetermined idea of something is by the abstraction of the mind derived from the simple ideas of sensation and reflection.’ Now ‘abstraction’ with Locke means the ‘separation of an idea from all other ideas that accompany it in its real existence.’ (Book II. chap. xii. sec. 1.) It is clear then that it is impossible to abstract an idea which is not there, in real existence, to be abstracted. Accordingly, if the ‘general idea of something’ is derived by abstraction from simple ideas of sensation and reflection, it must be originally given with these ideas, or it would not afterwards be separated from them. Conversely they must carry this idea with them, and cannot be simple ideas at all, but compound ones, each made up of ‘the general idea of something or being,’ and of an accident which this something supports. How then does the general idea of substance or ‘something,’ as derived, differ from the idea of ‘something,’ as given in the original ideas of sensation and reflection from which the supposed process of abstraction starts? What can be said of the one that cannot be said of the other? If the derived general idea is of something related to qualities, what, according to Locke, are the original ideas but those of qualities related to something? It is true that the general idea is of something, of which nothing further is known, related to qualities in general, not to any particular qualities. But the ‘simple idea’ in like manner can only be of an indeterminate quality, for in order to any determination of it, the idea must be put together with another idea, and so cease to be simple; and the ‘something,’ to which it is referred, must for the same reason be a purely indeterminate something. If, in order to avoid concluding that Locke thus unwittingly identified the abstract general idea of substance with any simple idea, we say that the simple idea, because not abstract, is not indeterminate but of a real quality, defined by manifold relations, we fall upon the new difficulty that, if so, not only does the simple idea become manifoldly complex, but just such an ‘idea of a particular sort of substance’ as, according to Locke, is derived from the derived idea of substance in general. As an idea of a quality, it is also necessarily an idea of a correlative ‘something;’ and if it is an idea of a quality in its reality, i.e. as determined by various relations, it must be an idea of a variously qualified something, i.e. of a particular substance. Then not merely the middle of the twofold process by which we are supposed to get at ‘complex ideas of substances’—i.e. the abstract something; but its end—i.e. the particular something—turns out to be the same as its beginning.

Doctrine of abstraction inconsistent with doctrine of complex ideas.

40. The fact is, that in making the general idea of substance precede particular ideas of sorts of substances (as he certainly however confusedly does, in the 23rd chapter of the Second Book, [1] as well as by implication in his doctrine of modes. Book II. chap. xii. sec. 4), Locke stumbled upon a truth which he was not aware of, and which will not fit into his ordinary doctrine of general ideas: the truth that knowledge is a process from the more abstract to the more concrete, not the reverse, as is commonly supposed, and as Locke’s definition of abstraction implies. Throughout his prolix discussion of ‘substance’ and ‘essence’ we find two opposite notions perpetually cross each other: one that knowledge begins with the simple idea, the other that it begins with the real thing as particularized by manifold relations. According to the former notion, simple ideas being given, void of relation, as the real, the mind of its own act proceeds to bring them into relation and compound them: according to the latter, a thing of various properties (i.e. relations [2]) being given as the real, the mind proceeds to separate these from each other. According to the one notion the intellectual process, as one of complication, ends just where, according to the other notion, as one of abstraction, it began.

[1] See above, paragraph 35.

[2] Cf. Book II. chap, xxiii. sec. 37. Most of the simple ideas that make up our complex ideas of substances are only powers … e.g. the greater part of the ideas which make up our complex idea of gold … are nothing else but so many relations to other substances.’

The confusion covered by use of ‘particulars’.

41. The chief verbal equivocation, under which Locke disguises the confusion of these two notions, is to be found in the use of the word ‘particular,’ which is sometimes used for the mere individual having no community with anything else, sometimes for the thing qualified by relation to a multitude of other things. The simple idea or sensation; the ‘something’ which the simple idea is supposed to ‘report,’ and which Locke at his pleasure identifies with it; the complex idea; and the thing as the collection of the properties which the simple idea ‘reports,’ all are merged by Locke under the one term ‘particulars.’ As the only consistency in his use of the term seems to lie in its opposition to ‘generals,’ we naturally turn to the passage where this opposition is spoken of most at large.

Locke’s account of abstract general ideas.

42. ‘General and universal belong not to the real existence of things, but are the inventions and creatures of the understanding, made by it for its own use, and concern only signs, whether words or ideas. Words are general when used for signs of general ideas, and so are applicable indifferently to many particular things; and ideas are general, when they are set up as the representatives of many particular things; but universality belongs not to things themselves, which are all of them particular in their existence, even those words and ideas which in their signification are general. When therefore we quit particulars, the generals that rest are only creatures of our own making, their general nature being nothing but the capacity they are put into by the understanding, of signifying or representing many particulars. For the signification they have is nothing but a relation that by the mind of man is added to them. … The sorting of things under names is the workmanship of the understanding, taking occasion from the similitude it observes among them to make abstract general ideas, and set them up in the mind, with names annexed to them, as patterns or forms (for in that sense the word form has a very proper signification), to which as particular things are found to agree, so they come to be of that species, have that denomination, or are put into that classis. For when we say this is a man, that a horse; this justice, that cruelty, what do we else but rank things under different specific names, as agreeing to those abstract ideas, of which we have made those names the signs? And what are the essences of those species, set out and marked by names, but those abstract ideas in the mind; which are, as it were, the bonds between particular things that exist, and the names they are to be ranked under?’ (Book III. chap. iii. secs. 11 and 13.)
