Note 320 — Chapter XX · (continued 3)

This is the questionable part of Hobbes’s theory of syllogism. According to the common and obvious understanding, the mind, in the major premise, Animal est Corpus, does not reflect on the subject of the minor, Homo, as occupying space, but on the subject of the major, Animal, which includes indeed the former, but is mentally substituted for it. It may sometimes happen, that where this predicate of the minor term is manifestly a collective word that comprehends the subject, the latter is not as it were absorbed in it, and may be contemplated by the mind distinctly in the major; as if we say, John is a man: a man feels; we may perhaps have no image in the mind of any man but John. But this is not the case where the predicated quality appertains to many things visibly different from the subject; as in Hobbes’s instance Animal est Corpus, we may surely consider other animals as being extended and occupying space besides men. It does not seem that otherwise there could be any ascending scale from particulars to generals, as far as the reasoning faculties, independent of words, are concerned. And if we begin with the major premise of the syllogism, this will be still more apparent.
