i. The ninth trope is the more or less frequent occurrence of things,

which likewise alters one’s judgment upon the things. What happens seldom is more highly esteemed than what comes to pass frequently; and custom brings about the fact that one judges in this way and the other in that way. Custom is thus made a circumstance which also permits us to say that things appear so and so to us, but not universally and generally that they are so.[204] When men say of any particular things that “this is so,” circumstances may be instanced in which the opposite predicate is applicable to them also. If, for example, we remain at the abstraction of the man, does it really signify whether or not we have a prince?—No. States?—No. A republic?—No, and so on, for they are here and not there.

k. The tenth trope mainly concerns ethics and is related to manners, customs and laws. What is moral and legal is likewise not such; for what is here considered to be right is elsewhere held to be wrong. The attitude of Scepticism in this regard is to show that the opposite of what is maintained as valid law holds equally good. As regards the ordinary understanding respecting the validity of this and that maxim, _e.g._ that the son has to pay the debts of his father, the ultimate and indeed only ground lies in its being said that this is true in its immediacy, for it holds good as law or custom. As against this the Sceptics likewise prove the opposite, saying for instance, that the son has, indeed, to undertake the debts of the father by the law of Rhodes; but in Rome he does not require to do so, if he has renounced his claim on the paternal goods.[205] As in the existence of what is determined, which is held to be true because it is, the opposite is shown to exist; so in the case of laws, if their ground is that they are in force, their opposite can be demonstrated. The natural man has no consciousness of the presence of opposites; he lives quite unconsciously in his own particular way, in conformity with the morality of his town, without ever having reflected on the fact that he practises this morality. If he then comes into a foreign land, he is much surprised, for through encountering the opposite he for the first time experiences the fact that he has these customs, and he immediately arrives at uncertainty as to whether his point of view or the opposite is wrong. For the opposite of what held good to him holds equally good, and he does not possess any further ground for his practice; so that since the one holds good equally with the other, neither holds good.

We now see in these modes that, properly speaking, they are not logical modes at all, nor have they to do with the Notion, for they proceed directly against empiricism. Something is by immediate certainty given out as being true, the opposite of this last is from some other point of view demonstrated to be equally true, and thus its other-being is set forth as valid. The different modes in which the non-validity of the first and the validity of the other-being relate to one another, are ranged under the above heads. If we now classify these ten tropes in conformity with the plan indicated above by Sextus (p. 347), we find in the first four tropes the dissimilarity of the object to depend on the judging subject, because that which judges is either the animal or the man or one of his senses or particular dispositions in him. Or the dissimilarity depends on the object, and here we come to the seventh and tenth tropes, since first the amount makes a thing into something quite different, and then the code of morals in different places makes itself the only absolute, excluding and prohibiting any other. The fifth, sixth, eighth and ninth tropes finally deal with a union of both sides, or these all together contain the relationship; this is a demonstration that the object does not present itself in itself, but in relation to something else.

From content and form we see in these modes their early origin; for the content, which has only to deal with Being, shows its change only, takes up only the variability of its manifestation, without showing its contradiction in itself, _i.e._ in its Notion. But in form they show an unpractised thought, which does not yet bring the whole of these examples under their universal points of view, as is done by Sextus, or which places the universal, relativity, alongside of its particular modes. On account of their dulness we are not accustomed to lay great stress on such methods, nor esteem them of any value; but, in fact, as against the dogmatism of the common human understanding they are quite valid. This last says directly, “This is so because it is so,” taking experience as authority. Now through these modes this understanding will be shown that its belief has contingencies and differences within it, which at one time present a thing in this way and at another time in that way; and thereby it will be made aware that it itself, or another subject, with equal immediacy and on the same ground (on none at all), says: “It is not so, for it really is the opposite,” Thus the signification of these tropes has still its value. Should faith or right be founded on a feeling, this feeling is in me, and then others may say: “It is not in me.” If one person’s tastes are to be accepted as authoritative, it is not difficult to demonstrate that another person’s tastes are utterly opposite, but Being is thereby degraded into seeming, for in every assurance such as that, the opposite holds equally good.

2. THE LATER TROPES.

The five other sceptical tropes have an entirely different character, and it is at once evident that they indicate quite another point of view and degree of culture as regards philosophic thought; for they pertain more to thinking reflection, and contain the dialectic which the determinate Notion has within it. Sextus Empiricus[206] sets them forth as follows:—

a. The first trope is the diversitude in opinions (ἀπὸ τῆς διαφωνίας), and that not among animals and men, but expressly among philosophers; of this matter we have just spoken above (pp. 349, 350). Sextus, and an Epicurean quoted by Cicero (Vol. I. p. 16), adduce the manifold nature of dogmas, and from this the conclusion is drawn that the one has just as much support as the other. Philosophers and others still make copious use of this sceptical trope, which is consequently in great favour: on account of the diversitude in philosophies, they say, Philosophy has no value, and truth is unattainable because men have thought about it in ways so contradictory. This diversitude in philosophic opinion is said to be an invincible weapon against Philosophy; but the category of difference is very barren, and we have said in the introduction (Vol. I. pp. 17-19) how it is to be understood. The Idea of Philosophy is to all philosophers one and the same, even if they themselves are not aware of it; but those who speak so much of this diversity know as little about it. The true difference is not a substantial one, but a difference in the different stages of development; and if the difference implies a one-sided view, as it does with the Stoics, Epicureans, and Sceptics, in their totality undoubtedly we first reach truth.

b. A very important trope is that of failing into an infinite progression (ἡ εἰς ἄπειρον ἔκπτωσις); by it the Sceptics show that the reason which is brought forward for an assertion itself again requires a reason, and this again another, and so on into infinitude; from this suspension of judgment thus likewise follows, for there is nothing which can furnish a solid foundation. Consequently no permanent ground can be pointed out, for each continues to press further and further back, and yet finally a cessation must be made. In more recent times many have plumed themselves on this trope, and, in fact, it is as regards the understanding and the so-called syllogism (_supra_, pp. 222, 223), a trope of great force. For if deduction from reasons is made the power of knowledge, we must, on the other hand, remember that by so doing we have premises which are quite ungrounded.
