analysis conducts us. We are all, as we at present stand, either sceptics or idealists, every man of us. Shall the analysis, then, be given up? Not if it can be substantiated by any good plea: for _truth_ must be accepted, be the consequences what they may. Can the analysis, then, be made good either by observation or by reasoning,--the only competent authorities, now that belief has been declared _hors de combat_? Stewart says that Reid made it good by means of direct observation; but the claim is too ridiculous to be listened to for a single instant. We have also shown that reasoning is incompetent to make out and support the analysis; and therefore our conclusion is, that it falls to the ground as a thing altogether impracticable as well as false, and that the attempt to re-establish it ought never, on any account, to be renewed. * * * * * We have dwelt so long on the exposition of the psychological or analytic solution of the problem of perception, that we have but little space to spare for the discussion of the metaphysical doctrine. We shall unfold it as briefly as we can. The principle of the metaphysical doctrine is precisely the opposite of the principle of the psychological doctrine. The one attempts all analysis; the other forbears from all analysis of the given fact--the perception of matter. And why does metaphysic make no attempt to dissect this fact? Simply because the thing cannot be done. The fact yields not to the solvent of thought: it yields not to the solvent of observation: it yields not to the solvent of belief, for man has no belief in the existence of matter from which perception (present and remembered) has been withdrawn. An impotence of the mind does indeed apparently resolve the supposed synthesis: but essential thinking exposes the imposition, restores the divided elements to their pristine integrity, and extinguishes the theory which would explain the _datum_ by means of the concurrence of a subjective or mental, and an objective or material factor. The convicted weakness of psychology is thus the root which gives strength to metaphysic. The failure of psychology affords to metaphysic a foundation of adamant. And perhaps no better or more comprehensive description of the object of metaphysical or speculative philosophy could be given than this,--that it is a science which exists, and has at all times existed, chiefly for the purpose of exposing the vanity and confounding the pretensions of what is called the "science of the human mind." The turning-round of thought from psychology to metaphysic is the true interpretation of the Platonic conversion of the soul from ignorance to knowledge--from mere opinion to certainty and satisfaction: in other words, from a discipline in which the thinking is only _apparent_, to a discipline in which the thinking is _real_. Ordinary observation does not reveal to us the real, but only the apparent revolutions of the celestial orbs.
