Thus the universal method of Scepticism was, as Sextus Empiricus puts it (Pyrrh. Hyp. I. c. 4, §§ 8-10; c. 6, § 12): “a power of in some way or other setting what is felt, and what is thought, in opposition, whether it be the sensuous to the sensuous, and what is thought to what is thought, or what is sensuous to what is thought, or what is thought to what is sensuous, i.e. showing that any one of these has as much force and weight as its opposite, and is hence equivalent as far as conviction and non-conviction are concerned. From this the suspension of judgment (ἐποχή) results, in conformity with which we select and posit nothing, and thereby complete freedom from all mental emotion is attained. The principle of Scepticism is thus found in the proposition that each reason is confronted by another, which holds equally good. We do not, however, necessarily accept affirmation and negation as opposite grounds, but merely those that conflict with one another.” That which is felt is really existence for sensuous certainty, which simply accepts it as truth; or it is that which is felt in the Epicurean form, which consciously asserts it to be true. What is thought is in the Stoic form a determinate Notion, a content in a simple form of thought; both these classes, immediate consciousness and thinking consciousness, comprehend everything which is in any way to be set in opposition. In as far as Scepticism limits itself to this, it is a moment in Philosophy itself, which last, having an attitude of negativity in relation to both, only recognizes them as true in their abrogation. But Scepticism thinks that it reaches further; it sets up a pretension of venturing against the speculative Idea and conquering it; Philosophy, however, since Scepticism itself is present in it as a moment, rather overcomes it (supra, p. 330). As far as what is sensuous and what is thought in their separation are concerned, it certainly may conquer, but the Idea is neither the one nor the other, and it does not touch on the rational at all. The perpetual misunderstanding which those who do not know the nature of the Idea are under concerning Scepticism, is that they think that the truth necessarily falls into the one form or the other, and is thus either a determinate Notion or a determinate Being. Against the Notion as Notion, i.e. against the absolute Notion, Scepticism does not in any way proceed; the absolute Notion is rather its weapon of defence, though Scepticism has no consciousness of this. We shall on the one hand see Scepticism use that weapon against the finite, and on the other, how it tries its skill upon the rational.

But though, according to this, Scepticism always expresses itself as if everything were in appearance only, the Sceptics go further than those who support the newer and purely formal idealism. For they deal with content, and demonstrate of all content that it is either experienced by the senses or thought, and consequently that it has something in opposition to it. Thus they show in the same thing the contradiction that exists, so that of everything that is presented the opposite also holds good. This is the objective element in Scepticism in its manifestation, and that through which it is not subjective idealism. Sextus (Pyrrh. Hyp. I. c. 13, §§ 32, 33) says: “Thus, for instance, the sensuous is set against the sensuous by our being reminded of the fact that the same tower when looked at near is square and when regarded in the distance looks round;” and hence the one assertion is as good as the other. This, indeed, is a very trivial example, but its interest lies in the thought that is present in it. “Or what is thought is set in opposition to what is thought. As to the fact that there is a providence,” which rewards the good and punishes the evil, “men appeal,” as against those who deny it, “to the system of the heavenly bodies; to this it is objected that the good often fare badly and the evil well, from which we demonstrate that there is no providence.” As to the “opposition of what is thought to the sensuous,” Sextus adduces the conclusion of Anaxagoras, who asserts of the snow, that although it appears to be white, regarded in relation to the reasons given by reflection it is black. For it is frozen water, but water has no colour and hence is black; consequently snow must be the same.

We must now consider further the method in which the Sceptics proceed, and it consists in this, that they have brought the universal principle that each definite assertion has to be set over against its ‘other,’ into certain forms, not propositions. Thus, in view of the nature of Scepticism, we cannot ask for any system of propositions, nor will this philosophy really be a system; just as little did it lie in the spirit of Scepticism to form a school, properly speaking, but only an external connection in the wider sense of the word. Sextus (Pyrrh. Hyp. I. c. 8, § 16, c. 3, § 7) hence says that Scepticism is no selection (αἵρεσις) of dogmas, it is not a preference for certain propositions, but only that which leads, or rather which directs us (ἀγωγή) to live rightly and think correctly; thus it is in this way rather a method or manner by which only universal modes of that opposition are shown. Now since what sort of thoughts reveal themselves is a matter of contingency, the manner and mode of grasping them is contingent likewise; for in one the contradiction appears thus and in another otherwise. These determinate modes of opposition, whereby the withholding of assent comes to pass, the Sceptics called tropes (τρόποι), which are turned upon everything that is thought and felt in order to show that this is not what it is implicitly, but only in relation to another—that it thus itself appears in another, and allows this other to appear in it, and consequently that, speaking generally, what is, only seems; and this, indeed, follows directly from the matter in itself, and not from another which is assumed as true. If, for example, men say that empiric science has no truth because truth exists only in reason, this is only assuming the opposite of empiricism; likewise the truth of reason proved in itself is not a refutation of empiric science, for this last stands alongside of the former with equal rights as, and within the same.

Now since the sceptical doctrine consists in the art of demonstrating contradictions through these tropes, we only require to elucidate these modes. The Sceptics themselves, like Sextus, for example (Pyrrh. Hyp. I. c. 14, 15) distinguish in these forms the earlier and the later: ten of them belong to the elder Sceptics, that is to say to Pyrrho, and five were afterwards added by the later Sceptics, and Diogenes Laertius indeed tells us (IX. 88) that this was first done by Agrippa. From a specification of these it will be shown that the earlier are directed against the ordinary consciousness generally and belong to a thought of little culture, to a consciousness which has sensuous existence immediately before it. For they proceed against what we call common belief in the immediate truth of things, and refute it in a manner which is immediate likewise, not through the Notion but through the existence which is opposed to it. In their enumeration, too, there is this same absence of the Notion. But the five others appear to be better, have more interest, and are manifestly of later origin; they proceed against reflection, i.e. against a consciousness which relates itself to the developed understanding, and thus specially against thought-forms, scientific categories, the thought of the sensuous, and the determination of the same through Notions. Now though the most part of these may appear to us to be quite trivial, we must still be indulgent towards them, for they are historically, and consequently really, directed against the form “it is.” But without doubt it is a very abstract consciousness that makes this abstract form “it is” its object and combats it. However trivial then and commonplace these tropes may always appear to be, even more trivial and commonplace is the reality of the so-called external objects, that is, immediate knowledge, as when, for instance, I say “This is yellow.” Men ought not to talk about philosophy, if in this innocent way they assert the reality of such determinations. But this Scepticism was really far from holding things of immediate certainty to be true; thus it actually stands in contrast to modern Scepticism, in which it is believed that what is in our immediate consciousness, or indeed, all that is sensuous, is a truth (supra, pp. 331, 332). As distinguished from this, the older Scepticism, the modes of which we would now consider further, is directed against the reality of things.

[1. The Earlier Tropes.]

In the earlier tropes we see the lack of abstraction appearing as the incapacity to grasp their diversitude under more simple general points of view, although they all, in fact, partly under a simple conception and partly in their difference, do in fact converge into some necessary simple determinations. From all alike, in relation to immediate knowledge, is the insecurity demonstrated of that of which we say “it is.” Sextus Empiricus (Pyrrh. Hyp. I. c. 14, § 38) even remarks, that “all the tropes may be summed up in three: the one is the judging subject; the other that respecting which the judgment is made; the third that which contains both sides”—the relation of subject and object. If thought is developed further, it embraces things in these more general determinations.

a. “The first trope is the diversitude in animal organization, according to which different living beings experience different conceptions and sensations respecting the same object. This the Sceptics conclude from the different nature of their origin, because some are brought into being through copulation and others without copulation” (from a generatio æquivoca): “but of the first some are hatched from eggs, and others come immediately living into the world, &c. Thus it is a matter of no doubt that this difference of origin produces opposite constitutions, temperaments, &c. The variety in the parts of the body, and particularly in those which are given to the animal for purposes of distinguishing and feeling, thus produces in them the greatest differences in conceptions. For instance, the jaundiced patient sees as yellow what to others appears white,” and as green, what to the latter seems blue. “Similarly the eyes of animals are differently constructed in different species, and have different colours, being pale, grey or red; consequently what is perceived thereby must be different.”[197]

This difference in the subject undoubtedly establishes a difference in perception, and this last a difference between the conception and the nature of the object of perception. But if we say “That is,” we mean something fixed, maintaining itself under all conditions; whereas in opposition to this the Sceptics show that everything is variable. But if they thereby destroy similarity and identity for the senses, and consequently this universality, another steps in, for universality or existence rests simply in the fact of men knowing that, in the hackneyed example of the jaundiced man, things appear so to him, i.e. the necessary law is known whereby a change of sensation arises for him. But certainly it is implied in this that the first sensuous universality is not true universality, because it is one immediate and unknown; and in it as sensuous existence, its non-universality is rightly demonstrated within itself through another universality. As against the statement “This is blue because I see it as such,” which clearly makes sight the ground of its being asserted to be blue, it is quite fair to point to another who has immediate perception of the object and for whom it is not blue.

b. The second trope, the diversitude of mankind in reference to feelings and conditions, amounts very much to the same thing as in the first case. In respect to difference in constitution of body, the Sceptics discover many idiosyncrasies. As regards the proposition “Shade is cool,” for instance, they say that someone felt cold in the sunlight, but warm in shadow; as against the statement “Hemlock is poisonous,” they instance an old woman in Attica who could swallow a large dose of hemlock without harm—thus the predicate poisonous is not objective, because it suits the one and not the other. Because such great bodily differences are present amongst men, and the body is the image of the soul, men must have a diversity of mind likewise and give the most contradictory judgments, so that no one can know whom to believe. To judge by the greater number would be foolish, for all men cannot be inquired of.[198] This trope again relates to the immediate; if, therefore, what has to be done is merely to believe some statement inasmuch as it is made by others, undoubtedly nothing but contradiction takes place. But a belief like this, that is ready to believe anything, is, as a matter of fact, incapable of understanding what is said; it is an immediate acceptance of an immediate proposition. For it did not demand the reason; but the reason is, in the first place, the mediation and the meaning of the words of the immediate proposition. Diversitude in men is really something which now likewise appears in other forms. It is said that men differ in regard to taste, religion, &c.; that religion must be left for each to decide for himself; that each, from a standpoint of his own, must settle how things are to be regarded as far as religion is concerned. The consequence of this is that in regard to religion there is nothing objective or true, everything ends in subjectivity, and the result is indifference to all truth. For then there is no longer a church; each man has a church and a liturgy of his own, each has his own religion. The Sceptics more particularly—as those who in all times spare themselves the trouble of philosophizing, on some sort of pretext, and who try to justify this evasion—persistently preach the diversity of philosophies; Sextus Empiricus does this very expressly, and it may even be brought forward here, although it will appear more definitely as the first of the later tropes. If the principle of the Stoics, as it is in its immediacy, holds good, the opposite principle, that of the Epicureans, has just as much truth, and holds equally good. In this way, when it is said that some particular philosophy asserts and maintains certain propositions, the greatest diversity is undoubtedly to be found. For here we have the talk which we censured earlier (Vol. I. p. 16): “Since the greatest men of all times have thought so differently and have not been able to come to an agreement, it would be presumptuous on our part to believe we had found what they could not attain to,” and with those who speak thus, the timid shrinking from knowledge makes out the inertness of their reason to be a virtue. Now if the diversity cannot be denied, because it is a fact that the philosophies of Thales, Plato, and Aristotle were different, and that this was not merely apparently the case, but that they contradicted one another, this way of wishing in such statements of them to gain a knowledge of the philosophies, shows a want of understanding as regards Philosophy; for such propositions are not Philosophy, nor do they give expression to it. Philosophy is quite the reverse of this immediacy of a proposition, because in that the very knowledge that is essential is not taken into account; hence such men see everything in a philosophy excepting Philosophy itself, and this is overlooked. However different the philosophic systems may be, they are not as different as white and sweet, green and rough; for they agree in the fact that they are philosophies, and this is what is overlooked. But as regards the difference in philosophies, we must likewise remark upon this immediate validity accorded to them, and upon the form, that the essence of Philosophy is expressed in an immediate manner. As regards this ‘is’ the trope undoubtedly does its work, for all tropes proceed against the ‘is,’ but the truth is all the time not this dry ‘is,’ but genuine process. The relative difference in philosophies is, in their mutual attitude towards one another (see the fifth trope), always to be comprehended as a connection, and therefore not as an ‘is.’

c. The third trope turns on the difference in the constitution of the organs of sense as related to one another; e.g. in a picture something appears raised to the eye but not to the touch, to which it is smooth, &c.[199] This is, properly speaking, a subordinate trope, for in fact a determination such as this coming through some sense, does not constitute the truth of the thing, what it is in itself. The consciousness is required that the unthinking description which ascribes existence to blue, square, &c., one after the other, does not exhaust and express the Being of the thing; they are only predicates which do not express the thing as subject. It is always important to keep in mind that the different senses grasp the same thing in contradictory ways, for by this the nullity of sensuous certainty is revealed.
