The extreme nicety with which gauging implements are fitted seems at first thought to be unnecessary, but it must be remembered that a cylindrical joint in ordinary machine fitting involves a precision almost beyond the sense of feeling, and that any sensible variation in turning gauges is enough to spoil a fit.
Besides its influence on the formation and direction of political eloquence, the doctrine professed by Protagoras had a far-reaching effect on the subsequent development of thought. Just as Cynicism was evolved from the theory of Hippias, so also did the teaching which denied Nature and concentrated all study on subjective phenomena, with a tendency towards individualistic isolation, lead on to the system of Aristippus. The founder of the Cyrenaic school is called a Sophist by Aristotle, nor can the justice of the appellation be doubted. He was, it is true, a friend and companion of Socrates, but intellectually he is more nearly related to Protagoras. Aristippus rejected physical studies, reduced all knowledge to the consciousness of our own sensations, and made immediate gratification the end of life. Protagoras would have objected to the last principle, but it was only an extension of his own views, for all history proves that Hedonism is constantly associated with sensationalism. The theory that knowledge is built up out of feelings has an elective affinity for the theory that action is, or ought to be, determined in the last resort by the most prominent feelings, which are pleasure and pain. Both theories have since been strengthened by the introduction of a new and more ideal element into each. We have come to see that knowledge is constituted not by sensations alone, but by sensations grouped according to certain laws which seem to be inseparable from the existence of any consciousness whatever. And, similarly,100 we have learned to take into account, not merely the momentary enjoyments of an individual, but his whole lifes happiness as well, and not his happiness only, but also that of the whole community to which he belongs. Nevertheless, in both cases it is rightly held that the element of feeling preponderates, and the doctrines of such thinkers as J. S. Mill are legitimately traceable through Epicurus and Aristippus to Protagoras as their first originator.The whole meaning and value of such excessively abstract propositions must lie in their application to the problems which they are employed to solve. Aristotle made at once too much and too little of his. Too muchfor he employed them to refute doctrines not really involving any logical inconsistencythe theory of Heracleitus, that everything is in motion; the theory of Anaxagoras, that everything was originally confused together; the theory of Protagoras, that man is the measure of all things. Too littlefor he admitted a sphere of possibilities where logical definition did not apply, and where subjects simultaneously possessed the capacity of taking on one or other of two contradictory attributes.

It was a few days later before Hetty thought of her promise to Balmayne. It was a fine bright afternoon with a strong sunshine, so that even the deserted house in Lytton Avenue looked almost cheerful. With a feeling that she might have been taken for a burglar or a house-breaker, Hetty let herself in.Owing to the slight importance which Aristotle attaches to judgments as compared with concepts, he does not go very deeply into the question, how do we obtain our premises? He says, in remarkably emphatic language, that all knowledge is acquired either by demonstration or by induction; or rather, we may add, in the last resort by the latter only, since demon388stration rests on generals which are discovered inductively; but his generals mean definitions and abstract predicates or subjects, rather than synthetic propositions. If, however, his attention had been called to the distinction, we cannot suppose that he would, on his own principles, have adopted conclusions essentially different from those of the modern experiential school. Mr. Wallace does, indeed, claim him as a supporter of the theory that no inference can be made from particulars to particulars without the aid of a general proposition, and as having refuted, by anticipation, Mills assertion to the contrary. We quote the analysis which is supposed to prove this in Mr. Wallaces own words:I THINK that there is no better occasion to deal with the question whether there was a franc-tireur-guerilla in Belgium than after the chapter on the destruction of Vis.Will you have enough gas?
