INDUCTION

[L:104] As conclusion "from many to all", induction is a manner of conclusion of judgment, the other being analogy, which is "from many determinations and properties in which things of the same kind agree, to the others so far as they belong to the same principle." Induction concludes "what appertains to many things of a genus, that appertains also to the remainder" (analogy concludes "from partial similarity of two things to total similarity"). Induction and analogy are not types of syllogisms, "but only logical presumptions or empirical conclusions", because they do not yield necessity. Induction does, however, yield "empirical certainty".
