We may regard the question of validity as settled for one class of judgments, namely, analytic judgments. They formed the real subject matter of the second part of our inquiry. Since an analytic judgment asserts of an object only what is contained in the definition of the object, it therefore correlates with the object a sign that by agreement is fixed as a sign for that object. It provides a unique correlation in conformity with the definition of uniqueness, and is thus absolutely true. The proposition "Analytic judgments are absolutely valid" is itself an analytic judgment. Such judgments have nothing whatever to do with knowledge of reality, and may therefore be completely separated from it. Their realm is that of thinking, not of being.
