Beweis und Rechtfertigung (Objektivistische Studien Buch 2)

By David Kelley

Knowledge must be grounded in evidence in accordance with epistemological principles. This monograph distinguishes two kinds of principle: rules of evidence and rules of justification.

Rules of evidence, such the canons of inductive and deductive logic, specify what sort of evidence is relevant to what sort of conclusion. Rules of justification specify what a person's cognitive state must be if he is to be justified in accepting a conclusion. This distinction makes it possible to explain how our knowledge can be fully justified all the way down to its foundations in perception.
