I have no objection to the pooh-pooh-ing of fairies, provided it be critical pooh-pooh-ing; but I wish I had the leisure to place before those gentlemen a work to be entitled The History of Pooh-pooh-ing. I think it would do them good; and make room in their minds for an essay /1

With Speculative Rhetoric, Logic, in the sense of Normative Semeotic, is brought to a close. But now we have to examine whether there be a doctrine of signs corresponding to Hegel's objective logic; that is to say, whether there be a life in Signs, so that--the requisite vehicle being present-- /1

In order to cover every possibility, this should be founded on a general doctrine of methods of attaining purposes, in general; and this, in turn, should spring from a still more general doctrine of the nature of teleological action, in general.

Nowadays methods alone can arrest attention strongly; and these are coming in such flocks that the next step will surely be to find a method of discovering methods. This can only come from a theory of the method of discovery.

“So long as an opinion is strongly rooted in the feelings, it gains rather than loses in stability by having a preponderating weight of argument against it.” — John Stuart Mill, The Subjection of Women

(But do not let me be understood as saying that a Form possesses, itself, Identity in the strict sense; that is, what the logicians, translating arithmo, call ‘numerical identity.’)” [N.B. In the text, ‘arithmo’ is written in Greek letters.]

“The enslavement of language in prattle is joined by the enslavement of things in folly almost as its inevitable consequence.” — Walter Benjamin, “On Language as Such and on the Language of Man”

“But why do that, when the thought itself is present to us?” Such, substantially, has been the interrogative objection raised by more than one or two superior intelligences, among whom I single out an eminent and glorious General.

Come on, my reader, and let us construct a diagram to illustrate the general course of thought; I mean a System of diagrammatization by means of which any course of thought can be represented with exactitude.

All these ideas may be said to have virtually existed in the form of the Boolian algebra originally given by Boole. But in 1870 I greatly enlarged and I may say revolutionized the subject by the virtual introduction of an entire new kind of abstractions.

It is the relation that M has to M and to B and that B has to B but that B does not have to M. It is the connecting link between the general ideas of logical dependence and the idea of the sequence of quantity.

I have only noticed a few of the most interesting of these abstractions. But I have not mentioned the most interesting of all the dyadic relations, that of inclusion, the great importance of which, now generally recognized, was first pointed out and demonstrated by me in 1870.

As an example of a triadic relation between relations take the relation between the 1st, 2nd and 3rd relations between M and B. That is the relation between first the relation of M only to B only, of B only to M only, and of otherness of M to B and of B to M. /1

I furthermore show that they invariably leave the doors open, theoretically and practically, to bad reasoning. In fact, there are no rules at all, for the most part, which follow as necessary corollaries from the theories. From the ordinary theories of hypotheses, on the other hand,rules do flow; /1

I show that the arguments which their authors identify with inductions have in some cases no force at all, but lead to manifest absurdity, and that in no cases are they nearly as strong as the true inductive argument.

Those four relations are dyadic relations. That is,considered as abstractions their existence consists in something being true of two primary substances.Thus to say that M is in the relation of otherness to B is to say that M is other than B which is a fact about the two primary substances M and B.
