the key maxims associated with the syllogisms in Barbara and Celarent, variously created, and related to Aristotle. "Whatever is affirmed (rejected) of a whole class or type might affirmed (rejected) of every part." The four emotions of first figure were held becoming directly validated by this dictum, which was presented with due to the fact motive when it comes to conventional reductions for the final three syllogistic figures into the first. See additionally Aristotle's dictum. -- A.C.
The fact is that the uniformity of nature stands to induction as the axioms of syllogism do to syllogism; they are not premises, but conditions of inference, which ordinary men use spontaneously, as was pointed out in Physical Realism, and afterwards in Venn's Empirical Logic. The axiom of contradiction is not a major premise of a judgment: the dictum de omni et nullo is not a major premise of a syllogism: the principle of uniformity is not a major premise of an induction.
