Abstract

The main idea or the concept of coherence can be expressed in the following way: The more the statements belonging to a given theory approximate a perfect supportive structure, the more coherent the theory. The degree of perfection of a supportive structure depends on the degree to which the following criteria of coherence are fulfilled: (1) the greatest possible number of supported statements belonging to the theory in question; (2) the greatest possible length of chains of reasons belonging to it; (3) the greatest possible number of strongly supported statements belonging to the theory; (4) the greatest possible number of connections between various supportive chains belonging to the theory; (5) the greatest possible number of preference relations between various principles belonging to it; (6) the greatest possible number and complexity of reciprocal supportive relations between various statements belonging to the theory; (7) the greatest possible number of universal statements belonging to the theory; the greatest possible number of general concepts belonging to it; the highest possible degree of generality of concepts implemented within it; the greatest possible number of resemblances between concepts used within it; (8) the greatest possible number of conceptual cross‐connections between various theories; (9) the greatest possible number of cases covered by the theory; and (10) the greatest possible number of fields of life covered by the theory.
