This principle will justify the substitution of 'not-wise' for 'foolish'; but it will also legitimate the above cases (concerning 'human life' and 'Socrates') as immediate inferences, with innumerable others that might be based upon the doctrine of relative terms: for example, _The hunter missed his aim_: therefore, _The prey escaped_.

And from this principle it will further follow that all apparent syllogisms, having one premise a verbal proposition, are immediate inferences (_cf._ chap.ix.Sec.

4).
Closely connected with such cases as the above are those mentioned by Archbishop Thomson as "Immediate Inferences by added Determinants" (_Laws of Thought_, Sec.

87).

He takes the case: '_A negro is a fellow-creature_: therefore, _A negro in suffering is a fellow-creature in suffering_.' This rests upon the principle that to increase the connotations of two terms by the same attribute or determinant does not affect the relationship of their denotations, since it must equally diminish (if at all) the denotations of both classes, by excluding the same individuals, if any want the given attribute.
