I will relate in my next Examination, what has hindered these savants from finding this basis. I must, before terminating this one, show to my readers how I believe one can distinguish the two kinds of skepticism of which I have just spoken. A simple question put to a skeptic philosopher will indicate whether he belongs to the school of Socrates or Pyrrho. He must before entering into any discussion reply clearly to this demand: Do you admit of any difference whatever between that which is and that which is not? If the skeptic belongs to the school of Socrates, he will necessarily admit a difference and he will explain it, which will make him recognized at once. If on the contrary, he belongs to that of Pyrrho, he will respond in one of three ways: either that he admits a difference, or that he admits none, or that he does not know whether one exists. If he admits it without explaining it, he is beaten; if he does not admit it, he falls into absurdity; if he pretends not to distinguish it, he becomes foolish and ridiculous.

He is beaten, if he admits a difference between that which is and that which is not; because that difference, admitted, proves the existence of being; the existence of being proves that of the skeptic who replies; and that existence proved, proves all the others, whether one considers them in him, or outside of him, which is the same thing for the moment.

He falls into absurdity, if he does not admit any difference between that which is and that which is not, for then one can prove to him that 1 is equal to 0, and that the part is as great as the whole.

He becomes foolish and ridiculous, if he dares to say that he does not know whether a difference really exists between that which is, and that which is not; for then one asks him what he did at the age of six months, at one year, two years, two weeks ago, yesterday? Whatever he replies, he will become the object of ridicule.

Behold the Pyrrhonian beaten, that is to say, the one who professes to doubt everything; since a single acknowledged difference bringing him irresistibly to a certainty, and since one certainty militates against all the others, there is no further doubt; and since, doubting no further, it is only a question then of knowing what he ought, or ought not to doubt: this is the true character of the skeptic of the Socratic School.

23. Abstain thou if ’tis evil; persevere if good.

But although one may bring the absolute skeptic to agree that a difference between good and evil can indeed exist, as he is forced to agree that one does exist between that which is and that which is not, just as I have demonstrated in my preceding Examination; would he not be right in saying, that to know in general, that good and evil can differ and consequently exist separately, does not prevent confounding them in particular; and that he can doubt that man may be able to make the distinction, until one may have proved to him that not alone their knowledge, but that some sort of knowledge is possible? Assuredly, this is pushing doubt very far. One could dispense with replying to this, since the skeptic already interrogated concerning the difference existing between what is and what is not has been forced to admit it and to acquire thus some sort of knowledge of being; but let us forget this, in order to examine why the savants of Germany have inadequately removed a difficulty which they have imposed upon themselves.

It is Kant, one of the ablest minds that Europe has produced since the extinction of learning, who, resolved to terminate with a single blow the struggle springing up unceasingly between dogmatism and skepticism, has been the first to form the bold project of creating a science which should determine, a priori, the possibility, the principles, and the limits of all knowledge.[500] This science, which he named Critical Philosophy, or method of judgment,[501] he has developed in several works of considerable length and very difficult of comprehension. I do not intend here to make an explanation of this science; for this labour, out of place in these Examinations, would carry me too far. My intention is only to show the point wherein it has given way, and how it has furnished new weapons for the skeptics, in not holding well to the promise that it had made of determining the principle of knowledge. Therefore, I will suppose the doctrine of Kant understood or partially so. Several works, circulated somewhat extensively in France, have unravelled it sufficiently to the savants.[502] I will only say what the authors of these works have been unable to say, and this will be the general result of the impression that the study of this doctrine has made upon me: it is that Kant, who pretends to found all his doctrine upon principles, a priori, abstraction being made of all the underlying notions of experience, and who, rising into an ideal sphere there to consider reason in an absolute way, independent of its effects so as to deduce from it a theory transcendental and purely intelligible, concerning the principle of knowledge, has done precisely the opposite from what he wished to do; for not finding what he sought, he has found what he has not sought, that is to say, the essence of matter. Let the disciples of this philosophy give attention to what I say. I have known several systems of philosophy and I have put considerable force into penetrating them; but I can affirm that there exists not a single one upon the face of the earth, wherein the primitive matter of which the Universe is composed may be characterized by traits as striking as in that of Kant. I believe it impossible either to understand it better or to depict it better. He uses neither figures, nor symbols; he tells what he sees with a candour which would have been appalling to Pythagoras and Plato; for what the Koenigsberg professor advances concerning both the existence and the non-existence of this matter,[503] and of its intuitive reality, and of its phenomenal illusion, and of its essential forms, time and space, and of the labour that the mind exercises upon this equivocal being, which, always being engendered, never, however, exists; all this, taught in the mysteries, was only clearly revealed to the initiate. Listen a moment to what has transpired in India: it is the fundamental axiom of the Vedantic school, the illustrious disciples of Vyasa and of Sankarâchârya, an axiom in accordance with the dogmas of the sacred books.

Matter exists [say these philosophers], but not of an existence such as is imagined by the vulgar; it exists but it has no essence independent of intellectual perceptions; for existence and perceptibility are, in this case, convertible terms. The sage knows that appearances and their exterior sensations are purely illusory and that they would vanish into nothingness, if the Divine energy which alone sustains them was for an instant suspended.[504]

I beg the disciples of Kant to give attention to this passage, and to remember what Plato has said of the same, that, sometimes matter exists and sometimes it does not exist[505]; as Justin the martyr, and Cyril of Alexandria have reproached him for it; and as Plutarch and Chalcidius have strongly remarked it,[506] in seeking to excuse this apparent contradiction.
