In the perusal of philosophical works I have been greatly benefited by a resolve, which, in the antithetic form and with the allowed quaintness of an adage or maxim, I have been accustomed to word thus: until you understand a writer’s ignorance, presume yourself ignorant of his understanding. This golden rule of mine does, I own, resemble those of Pythagoras in its obscurity rather than in its depth. If however the reader will permit me to be my own Hierocles, I trust, that he will find its meaning fully explained by the following instances. I have now before me a treatise of a religious fanatic, full of dreams and supernatural experiences. I see clearly the writer’s grounds, and their hollowness. I have a complete insight into the causes, which through the medium of his body has acted on his mind; and by application of received and ascertained laws I can satisfactorily explain to my own reason all the strange incidents, which the writer records of himself. And this I can do without suspecting him of any intentional falsehood. As when in broad daylight a man tracks the steps of a traveller, who had lost his way in a fog or by a treacherous moonshine, even so, and with the same tranquil sense of certainty, can I follow the traces of this bewildered visionary. I understand his ignorance.
On the other hand, I have been reperusing with the best energies of my mind the TIMAEUS of Plato. Whatever I comprehend, impresses me with a reverential sense of the author’s genius; but there is a considerable portion of the work, to which I can attach no consistent meaning. In other treatises of the same philosopher, intended for the average comprehensions of men, I have been delighted with the masterly good sense, with the perspicuity of the language, and the aptness of the inductions. I recollect likewise, that numerous passages in this author, which I thoroughly comprehend, were formerly no less unintelligible to me, than the passages now in question. It would, I am aware, be quite fashionable to dismiss them at once as Platonic jargon. But this I cannot do with satisfaction to my own mind, because I have sought in vain for causes adequate to the solution of the assumed inconsistency. I have no insight into the possibility of a man so eminently wise, using words with such half-meanings to himself, as must perforce pass into no meaning to his readers. When in addition to the motives thus suggested by my own reason, I bring into distinct remembrance the number and the series of great men, who, after long and zealous study of these works had joined in honouring the name of Plato with epithets, that almost transcend humanity, I feel, that a contemptuous verdict on my part might argue want of modesty, but would hardly be received by the judicious, as evidence of superior penetration. Therefore, utterly baffled in all my attempts to understand the ignorance of Plato, I conclude myself ignorant of his understanding.
In lieu of the various requests which the anxiety of authorship addresses to the unknown reader, I advance but this one; that he will either pass over the following chapter altogether, or read the whole connectedly. The fairest part of the most beautiful body will appear deformed and monstrous, if dissevered from its place in the organic whole. Nay, on delicate subjects, where a seemingly trifling difference of more or less may constitute a difference in kind, even a faithful display of the main and supporting ideas, if yet they are separated from the forms by which they are at once clothed and modified, may perchance present a skeleton indeed; but a skeleton to alarm and deter. Though I might find numerous precedents, I shall not desire the reader to strip his mind of all prejudices, nor to keep all prior systems out of view during his examination of the present. For in truth, such requests appear to me not much unlike the advice given to hypochondriacal patients in Dr. Buchan’s domestic medicine; videlicet, to preserve themselves uniformly tranquil and in good spirits. Till I had discovered the art of destroying the memory a parte post, without injury to its future operations, and without detriment to the judgment, I should suppress the request as premature; and therefore, however much I may wish to be read with an unprejudiced mind, I do not presume to state it as a necessary condition.
The extent of my daring is to suggest one criterion, by which it may be rationally conjectured beforehand, whether or no a reader would lose his time, and perhaps his temper, in the perusal of this, or any other treatise constructed on similar principles. But it would be cruelly misinterpreted, as implying the least disrespect either for the moral or intellectual qualities of the individuals thereby precluded. The criterion is this: if a man receives as fundamental facts, and therefore of course indemonstrable and incapable of further analysis, the general notions of matter, spirit, soul, body, action, passiveness, time, space, cause and effect, consciousness, perception, memory and habit; if he feels his mind completely at rest concerning all these, and is satisfied, if only he can analyse all other notions into some one or more of these supposed elements with plausible subordination and apt arrangement: to such a mind I would as courteously as possible convey the hint, that for him the chapter was not written.
Vir bonus es, doctus, prudens; ast haud tibi spiro.
For these terms do in truth include all the difficulties, which the human mind can propose for solution. Taking them therefore in mass, and unexamined, it required only a decent apprenticeship in logic, to draw forth their contents in all forms and colours, as the professors of legerdemain at our village fairs pull out ribbon after ribbon from their mouths. And not more difficult is it to reduce them back again to their different genera. But though this analysis is highly useful in rendering our knowledge more distinct, it does not really add to it. It does not increase, though it gives us a greater mastery over, the wealth which we before possessed. For forensic purposes, for all the established professions of society, this is sufficient. But for philosophy in its highest sense as the science of ultimate truths, and therefore scientia scientiarum, this mere analysis of terms is preparative only, though as a preparative discipline indispensable.
Still less dare a favourable perusal be anticipated from the proselytes of that compendious philosophy, which talking of mind but thinking of brick and mortar, or other images equally abstracted from body, contrives a theory of spirit by nicknaming matter, and in a few hours can qualify its dullest disciples to explain the omne scibile by reducing all things to impressions, ideas, and sensations.
But it is time to tell the truth; though it requires some courage to avow it in an age and country, in which disquisitions on all subjects, not privileged to adopt technical terms or scientific symbols, must be addressed to the Public. I say then, that it is neither possible nor necessary for all men, nor for many, to be philosophers. There is a philosophic (and inasmuch as it is actualized by an effort of freedom, an artificial) consciousness, which lies beneath or (as it were) behind the spontaneous consciousness natural to all reflecting beings. As the elder Romans distinguished their northern provinces into Cis-Alpine and Trans-Alpine, so may we divide all the objects of human knowledge into those on this side, and those on the other side of the spontaneous consciousness; citra et trans conscientiam communem. The latter is exclusively the domain of pure philosophy, which is therefore properly entitled transcendental, in order to discriminate it at once, both from mere reflection and representation on the one hand, and on the other from those flights of lawless speculation which, abandoned by all distinct consciousness, because transgressing the bounds and purposes of our intellectual faculties, are justly condemned, as transcendent . The first range of hills, that encircles the scanty vale of human life, is the horizon for the majority of its inhabitants. On its ridges the common sun is born and departs. From them the stars rise, and touching them they vanish. By the many, even this range, the natural limit and bulwark of the vale, is but imperfectly known. Its higher ascents are too often hidden by mists and clouds from uncultivated swamps, which few have courage or curiosity to penetrate. To the multitude below these vapours appear, now as the dark haunts of terrific agents, on which none may intrude with impunity; and now all aglow, with colours not their own, they are gazed at as the splendid palaces of happiness and power. But in all ages there have been a few, who measuring and sounding the rivers of the vale at the feet of their furthest inaccessible falls have learned, that the sources must be far higher and far inward; a few, who even in the level streams have detected elements, which neither the vale itself nor the surrounding mountains contained or could supply . How and whence to these thoughts, these strong probabilities, the ascertaining vision, the intuitive knowledge may finally supervene, can be learnt only by the fact. I might oppose to the question the words with which Plotinus supposes Nature to answer a similar difficulty. “Should any one interrogate her, how she works, if graciously she vouchsafe to listen and speak, she will reply, it
