An Examination of the Concept of “Self-Evidence” in Thomistic Natural Law Teaching

  • 43 Accesses

Abstract

As we noted in our opening chapter, there was considerable disagreement concerning the nature and the content of the class of self-evident, natural law principles. Some of the writers we discussed maintained that natural law consisted of only one such principle, while others argued that it contained several principles of this kind. Nor was the difference limited to the question of the number of principles —there was also a very marked variation in the principles themselves; in only a very few instances did any two writers agree on the precise principles belonging to the class in question. In attempting to reconcile this conflict in natural law teaching, we propose in this chapter to clarify and possibly solve the question as to the nature and number of self-evident principles contained in natural law. We intend to consider the possibility of being able to determine how many such precepts there are, and the manner in which they may be formulated.

It is interesting to note that in the De Veritate, written shortly after the Commentary on the Sentences, S. Thomas points out the inferiority of human to angelic nature in the matter of intuitive knowledge; even in first principles man cannot know truth nisi a sensu accipiendo.

  37. It is clear from these comments that the term “analytic” has a rather relative use. It would be incorrect to regard analytic propositions as comprising a certain finite class, what is analytic for one person or group of people may not be so for another. Furthermore while in the first instance we might not see a proposition as analytic, as we come to learn more about the terms involved so we see that it is analytic.

  45. From our understanding of this principle it would seem more accurate to describe it as “ontological” rather than “logical”. To describe it as “logical” could lead to the mistaken belief that it is analytic, but as we indicated earlier, this is not an adequate description, because it overlooks its intimate connexion with the nature of man.

Cronin, The Science of Ethics, I., Dublin, 1909, p. 609, takes a position similar to ours, for, when listing the natural inclinations possessed by man, he omits any mention of one concerned with man’s desire to know the truth about God.
