Suppose you doubt that rationally persuasive arguments can have just premises that are obviously false. But now consider:(X) Grass is red. Some arguments have merely obviously false premises.'Grass is red' is the only premise and is obviously false, so (X) should convince you that there are arguments with merely obviously false premises. On the face of it, there is nothing irrational about being so convinced by (X). But then (X) is a rationally persuasive argument with merely obviously false premises.A cheap (...) trick you say? Not so, say I — a trick yes, but, I shall argue, far from cheap. In ' 'P, Therefore, P' Without Circularity,' Roy Sorensen uses numerous examples like these to suggest, among other things ..
