Mr. Locke defines it, “That notice which the mind takes of its own operations.”

When we have a sensation, we have already seen, on various occasions, that the having the state of consciousness, and taking notice of it, are not two things, but one and the same thing. When we say that one sensation is more attended to than another, this, as we shall see [hereafter], is really tantamount to saying, that the one is more a sensation than the other.

In like manner, when we have an idea; the having the idea, the being conscious of the idea, knowing the idea, observing the idea, are only different names for the same thing. They mean the being conscious in a particular way. But the being conscious is to take notice of the consciousness. To be conscious, and not to take notice, is the same thing as to be 177 conscious, and not conscious. The notice is the consciousness, and the consciousness is the notice.

Thus far, therefore, it appears, with abundant evidence that Reflection is nothing but Consciousness; and Consciousness is the having the sensations and ideas. But what will be objected is, that we not only have Ideas; but we are capable of forming the idea of that particular state of mind which exists when we have an idea. It requires a close examination, to discover what is really meant by the language in which this objection is conveyed. The thing, however, to which it imperfectly points, can be made out; though, from the imperfection of the language which we must employ, it is not easy to explain it, with a certainty of being understood.

When it is said, that we can not only have a particular idea, but can form an idea of that state of mind, generally, which is called having an idea; this can mean nothing but the distinction between the particular and the general idea. It is affirmed, that we can not only have this idea, and that idea, but we can have the general idea of all ideas. This is true. But we know, by previous elucidations, what all this means. We can have the idea not only of this man, or that man, but we can have the idea of men in general. That is to say, we can group all individuals of a certain description into one class, to which class we give a name, equally applicable to every individual; which name, accordingly, being associated equally with individuals indefinite in number, calls up the ideas of individuals, indefinite in number, on every application of it.

This points out a double meaning of the word Idea; from which all the confusion of the language 178 about REFLECTION seems to have been derived. The same word, Idea, is both the particular, and the general name. It cannot be disputed, that so far as regards individual Ideas, the having an idea, and knowing it, the being in the state of consciousness, and knowing the state of consciousness, are one and the same thing. And, if the being in a state of consciousness, and knowing it, does not express all that is meant by reflecting upon it (where reflecting is not used in another sense, as equivalent with remembering), it will remain for those who believe there is anything more, to shew what it is.

That the general is derived from the particular, there will be no hesitation in allowing. The fact, therefore, so imperfectly stated, is, that, from individual states of consciousness, we rise, by generalization, as in other cases, to the general idea which embraces a class. General Ideas, on account of their complexity, are all apt to appear, to persons little accustomed to examine them closely, more or less mysterious. But general ideas, not of the steady objects of sense, but the fleeting states of consciousness, which we have so little under command, and for the naming of which we are so ill provided with terms, cannot fail to appear mysterious in a much greater degree. What we are now, therefore, contemplating is a case of generalization, which, how certainly soever, from the common laws of the human mind, we know that it is made, it is far from easy distinctly to conceive. And those of my readers, who have followed me easily in this deduction, may be satisfied they have made no slight progress in metaphysical science.

179 It is evident, when all this is clearly understood, that what has been mysteriously set forth, under the name of an Idea of REFLECTION, is simply the generalization of particular states of consciousness; which particular states of consciousness are our sensations and ideas.

There are various cases of this generalization, some more, some less, extensive.

In the same manner as we generalize the having of a single idea; and conceive, not the having of this idea, or that idea, but the having of any idea, and all ideas; we also generalize the having two associated ideas, and, from particulars, mount up to the general idea of the association, or train, of ideas.
