Abstract

The categorical logic fallacies are called formal fallacies because they are all violations of proper syllogistic form. This chapter deals with one of the common fallacies in Western philosophy, the illicit major and minor terms. The fallacies of illicit major term and illicit minor term have to do with distribution in syllogisms. The illicit process of the major term is much the same, except we would illicitly process the major term as opposed to the minor. So if we are only talking about some of something, then we cannot go on to conclude something about all of that something. We cannot distribute anything in the conclusion that was not distributed in the premises. But we may not have to distribute in the conclusion whatever was distributed in the premises.
