Contextual Appraisal theorem (Barseghyan-2015) Reason1

Barseghyan presents the following description of the deduction of the contextual appraisal theorem:

By the second law, in actual theory assessment a contender theory is assessed by the method employed at the time ... In addition, it follows from the first law for theories that a theory is assessed only if it attempts to enter into the mosaic; once in the mosaic, the theory no longer needs any further appraisal. In this sense, the accepted theory and the contender theory are never on equal footing, for it is up to the contender theory to show that it deserves to become accepted. In order to replace the accepted theory in the mosaic, the contender theory must be declared superior by the current method; to be “as good as” the accepted theory is not sufficient.

This reason for Contextual Appraisal theorem (Barseghyan-2015) was formulated by Hakob Barseghyan in 2015.1
