Formal Logic is the “master faculty” of the dialectic stage, and as such it not only teaches the tools of logic, but demonstrates how to use them in teaching. Thus the class of all triangles is a genus relative to the species scalene triangleand a species relative to the genus polygon. Genus-differentia is a concept in meaning-making wherein the genus states the broader category and the differentia, the specifics for a particular species/concept/item. My son struggles getting a nominative in the predicate consistently. This is one benefit, but we should also note the benefit they provide in helping to develop arguments.

The genus "Homo" first appeared on Earth between 1.5 and 2 million years ago. A species is defined by giving its genus (genos) and its differentia (diaphora): the genus is the kind under which the species falls, and the differentia tells what characterizes the species within that genus. It is the first step in an induction which, if carried out, would produce a generalization. Formal Logic is the “master faculty” of the dialectic stage, and as such it not only teaches the tools of logic, but demonstrates how to use them in teaching. this is a kind of that).

Lesson 2 Intro Logic - Genus and Species. A genus (plural genera) is a taxonomic rank used in the biological classification of living and fossil organisms, as well as viruses, in biology.In the hierarchy of biological classification, genus comes above species and below family.In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. In the chapter on “Classification” he teaches on genus and species, where he reminds us that the genus of a term is more abstract than the term itself, and the species of a term is more concrete.

ABSTRACT: Tanabe Hajime (1885-1962), another pole of the so-called Kyoto-School of Philosophy of modern Japan, attempts to construct a dialectical, triadic logic of genus, species and individual as a creative synthesis between Eastern and Western philosophy. A genus consists of a large number of organisms, whereas species consists of a fewer number of organisms. A genus may have several species under it and a number of genera could be from a single family or subfamily. In the above chart, the top dividing principle is “whether or not the action is due to oneself.” Under involuntary actions, the dividing principle between chance and necessity is “whether or not the cause is fixed and determined”; under necessity, the dividing principle between compulsion and nature is “whether it is external or internal.” Aristotle’s dividing principles between habit and craving or between anger and appetite are less clear, though the dividing principle under craving is obvious. Terms can be both a geenus and a species - a genus of the terms below it and a species of the term above it. Flashcards. species that fell within an earlier disclosed genus might be anticipated, if the earlier claimed genus was small enough so that each and every member of the earlier claimed genus could be at once envisaged.
