On all the other points of the modern metaphysical system, such as the nature of abstraction, judgment and reasoning, the materiality of the soul, free-will, the association of ideas, &c. Mr. Locke either halts between two opinions, or else takes the common-place side of the question. The motion of the system, which bears his name and which by this very delay gained all that it wanted to become popular, was retrograde in him, not progressive. The extracts I am about to give from his work will I think establish this point. They will at the same time show him to be a man of strong practical sense, of much serious thought and inquiry, and considerable freedom of opinion, and a real lover of truth, though not so bold and systematic a reasoner, or so great a dealer in paradoxes as some others. Moderation, caution, a wish to examine every side of a question, and an unwillingness to decide till after the most mature and circumspect investigation, and then only according to the clearness of the evidence, seem to have been the characteristics of his mind, none of which denote the daring innovator, or maker of a system. What there is of system in his work is Hobbes’s, as I have already shown: the deviations from its common sense and general observation are his own. There is throughout his reasoning the same contempt for the schoolmen, and the same preference of native, rustic reason to learned authority: the same notion of the necessity for reforming the system of philosophy, and of the possibility of doing this by a more exact use of words: there is the same dissatisfaction with the prevailing system, but he at the same time entertained doubts of his own. What he wanted was confidence and decision. The prolixity and ambiguity of his style seem to have arisen from this source: for he is never weary of examining and re-examining the same objection, and he states his arguments with so many limitations and with such a variety of expression to prevent misapprehension, that it is often difficult to guess at his real meaning. There is it must be confessed a sort of heaviness about him, a want of clearness and connection, which in spite of all his pains, and the real plodding strength of his mind he was never able to overcome. To return to his account of complex ideas: the beginning of his observations on this subject is as follows: ‘We have hitherto considered those ideas, in the reception whereof the mind is only passive, which are those simple ones received from sensation and reflection before mentioned, whereof the mind cannot make one to itself, nor have any idea which does not consist wholly of them. But as the mind is wholly passive in the reception of all its simple ideas, so it exerts several acts of its own, whereby out of its simple ideas, as the materials and foundations of the rest, the other are framed. The acts of the mind wherein it exerts its power over its simple ideas, are chiefly these three.
