This paintings introduces the topic of formal good judgment in terms of a method that's "like syllogistic logic". Its procedure, like outdated, conventional syllogistic, is a "term logic". The authors' model of good judgment ("term-function logic", TFL) stocks with Aristotle's syllogistic the perception that the logical types of statements which are all in favour of inferences as premises or conclusions may be construed because the results of connecting pairs of phrases via a logical copula (functor). This perception contrasts markedly with that which informs trendy ordinary formal common sense ("modern predicate logic", MPL). The publication is meant as a device for the creation of TFL to the start scholar of good judgment. it is also a bankruptcy introducing regular MPL. There are a number of workout sections and a precis of the most principles, legislation and ideas of TFL. For the philosophically orientated there are discussions of significant matters on the intersections of semantics, metaphysics, epistemology and good judgment.

Now ifthat STATE is a STATE of presence, the two statements that express it will be positive in valence. If it is a STATE of absence the two statements expressing it will be negative in valence. In effect when two statements are logically equivalent, both statements must be positive in valence or else both must be negative; thus no statement claiming presence can possibly be equivalent to a statement that claims absence. int another way: when two statements are equivalent they must be 'covalent' and not 'divalent'.
In accepting the first statement you accept the claim that the EXISTENCE OF A SCHOLAR WHO IS A GENTLEMAN AND A FARMER is a FACT. But if that STATE obtains so does the EXISTENCE OF A SCHOLAR WHO IS A FARMER AND A GENTLEMAN and so does THE EXISTENCE OF A GENTLEMAN WHO IS A FARMER. You cannot rationally accept the first claim and reject the other two. Thus, truth has consequences. Logic studies the consequences of truth claims. The study of how statements are truth related to one another is central to logic.
States of Affairs' We commonly speak of a statement as expressing a 'state of affairs'. Here one should distinguish between STATES that are expressed and the states that are signified. What a statement expresses is a proposition or STATE OF AFFAIRS, what it signifies, if anything, is a fact or state of affairs (lower case). False statements express STATES but they do not signify states. For example, THE EXISTENCE OF MERMAIDS is the STATE OF AFFAIRS expressed by 'there are mermaids'. But there is no such state of affairs as the existence of mermaids.
