Abstract

The solution of this problem is extremely important to the process of the development of logic. Its solution is of great theoretical significance in upholding the methodology of dialectical materialism; criticizing the sophistry of metaphysics, skepticism, and relativism; developing formal logic and symbolic logic; forming the scientific system of dialectical logic in the strict sense; and conducting research to strengthen all the concrete sciences. It also has enormous significance for the criticism of "leftist" and right-wing opportunism and revisionism, and especially for criticizing the counterrevolutionary revisionist line of the "gang of four."
