Is there an affirmative proposition corresponding to every denial?

The antecedent is the " subject " and the consequent is the " predicate " of a universal affirmative proposition.

A universal affirmative proposition ( " Every man is white " ) and the non-universal denial of that proposition in a way ( " Some man is not white " ) are called " contradictories ".
4.
A universal affirmative proposition, such as,'Every man is white'and a universal negative proposition having the same subject and predicate, such as,'No man is white,'are called " contrary ".

Whenever an affirmative proposition is apt to be verified for actually existing things, if two things, howsoever they are present according to arrangement and duration, cannot suffice for the verification of the proposition while another thing is lacking, then one must posit that other thing.

It is, of course, easy to say that it was contrary to the intention of the Legislature-a proposition which, by reason of its generality, it is difficult to bring to the test; but when one seeks to put as an affirmative proposition what the thing is which the Legislature has prohibited, there is, as it appears to me, an insuperable difficulty in the way of those who seek to insert by construction such a prohibition into the statute . }}

{{ quote | Until about the middle of the previous century induction was treated as a quite specific method of inference : inference of a universal affirmative proposition ( All swans are white ) from its instances ( a is a white swan, b is a white swan, etc . ) The method had also a probabilistic form, in which the conclusion stated a probabilistic connection between the properties in question . . . The Oxford English Dictionary defines induction, in the sense relevant here, as follows : " [ The ] process of inferring a general law or principle from the observation of particular instances . . ."

In response he devised his own " anti-razor : " " If three things are not enough to verify an affirmative proposition about things, a fourth must be added, and so on . " Although there have been a number of philosophers who have formulated similar anti-razors since Chatton's time, no one anti-razor has perpetuated in as much notability as Chatton's anti-razor, although this could be the case of the Late Renaissance Italian motto of unknown attribution " Se non ?vero, ?ben trovato " ( " Even if it is not true, it is well conceived " ) when referred to a particularly artful explanation.
