Truth-Claim. The claim that a proposition is sufficiently supported by evidence that warrants its acceptance as true. Though it need not be in propositional form, it should be able to be expressed in one. For a truth-claim to be meaningful certain conditions are required, for instance, that the proposition can be given a self-consistent formulation that permits the formulation of a self-consistent alternative. The logical subject of the proposition must be one that permits reference to it (not, for instance, an artificial term such as Bamwunk), and the predicate must be one that can be significantly assigned to the subject. The predicate "is pregnant" could be applied to a woman or a mare but not to a stallion or a man or a table. Nevertheless, when, precisely, the conditions are satisfied is in some cases very disputable. The concept is important in the philosophical analysis of Christian and other religious thought.
