Genus and Species Hierarchy. 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 unique … I used a similar chart in Calculus to show the arrangement between the types of elementary functions, in Physics for the various branches of physics, and in Doctrine for the “Liar, Lunatic, Lord” argument for the deity of Jesus. Created by. this is a kind of that). The names of sub-species and natural varieties are written beginning with the genus and species followed by the abbreviation ssp.

The Logic teacher not only presents this tool for use in other subjects, but also in teaching Logic itself. The narrower the genus, the more exact the definition will be. I used this tool in every course I taught, including Logic, Rhetoric, Calculus, Physics, and Doctrine. 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. For example, I used the tool of genus and species in my Logic class when I taught the difference between supported  and self-supporting statements. Required fields are marked *. For example Pelargonium x hortorum L.H. Genus and species are used in relation to modern humans, or Homo sapiens, as well. I used a similar chart in Calculus to show the arrangement between the types of elementary functions, in Physics for the various branches of physics, and in Doctrine for the “Liar, Lunatic, Lord” argument for the deity of Jesus. difference”. The broad definition says, “Species is what is arranged under the genus and is what the genus is predicated of with respect to what the thing is.” 8 Species can be considered a unified concept under a genus anywhere in the middle of the tree.
