Farther, individuality is sometimes used to express not so much the absolute difference or distinction between one individual and another, as a relation or comparison of that individual with itself, whereby we tacitly affirm that it is in some way or other the same with itself, or one idea. Now in one sense it is true of all existences whatever that they are literally the same with themselves; that is, they are what they are, and not something else. Each thing is itself, is that individual thing, and no other; and each combination of things is that combination, and no other. So also each individual conscious being is necessarily the same with himself; or in other words, that combination of ideas which represents any individual person is that combination of ideas, and not a different one. This literal and verbal is the only true and absolute identity which can be affirmed of any individual; which, it is plain, does not arise from a comparison of the different parts or successive impressions composing the general idea one with another, but each with itself or all of them taken together with the whole. I cannot help thinking that some idea of this kind is frequently at the bottom of the perplexity which is felt by most people who are not metaphysicians (not to mention those who are), when they are told that man is not always the same with himself, their notion of identity being that he must always be what he is. He is the same with himself, in as far as he is not another. When they say that the man is the same being in general, they do not really mean that he is the same at twenty that he is at sixty, but their general idea of him includes both these extremes, and therefore the same man, that is, the same collective idea, is both the one and the other. This however is but a rude logic. Not well understanding the process of distinguishing the same individual into different metaphysical sections, to compare, collate, and set one against the other (so awkwardly do we at first apply ourselves to the analytical art), to get rid of the difficulty the mind produces a double individual, part real and part imaginary, or repeats the same idea twice over; in which case it is a contradiction to suppose that the one does not correspond exactly with the other in all its parts. There is no other absolute identity in the case. All individuals (or all that we name such) are aggregates, and aggregates of dissimilar things. Here, then, the question is not how we distinguish one individual from another, or a number of things from a number of other things, which distinction is a matter of absolute truth, but how we come to confound a number of things together, and consider many things as the same, which cannot be strictly true. This idea must then merely relate to such a connexion between a number of things as determines the mind to consider them as one whole, each part having a much nearer and more lasting connexion with the rest than with any thing
