In our last critical thinking column we introduced the idea of intellectual standards and pointed out that all natural languages are repositories for such standards, which, when appropriately applied, serve as guides for assessing human reasoning. We argued that intellectual standards are necessary for cultivating the intellect and living a rational life, are presupposed in many concepts in modern natural languages, and are presupposed in every subject and discipline. In this column, the second in the series, we introduce and explicate some of the intellectual standards essential to reasoning well through the problems and issues implicit in everyday human life.
