The reference is made to the Post Analyt I II and it is impossible to understand the account of [Greek: epistaemae] without a perusal of the chapter, the additions to the definition referred to relate to the nature of the premisses from which [Greek: epistaemae] draws its conclusions they are to be “true, first principles incapable of any syllogistic proof, better known than the conclusion, prior to it, and causes of it.” (See the appendix to this Book.)

This is the test of correct logical division, that the membra dividentia shall be opposed, i.e. not included the one by the other.

The meaning of the [Greek: hepehi] appears to be this: the appeal is made in the first instance to popular language, just as it the case of [Greek: epistaemae], and will be in those of [Greek: phronaesis] and [Greek: sophia]. We commonly call Architecture an Art, and it is so and so, therefore the name Art and this so and so are somehow connected to prove that connection to be “coextensiveness,” we predicate one of the other and then simply convert the proposition, which is the proper test of any logical definition, or of any specific property.
