The philosopher considers the common-sense hypothesis of the world existing, which I will indicate with the letter “A” because of concision, and the sceptical hypothesis denying the existence of the world, which I will indicate with the letter “B” from now on. Thus, Russell claims that although B is logically possible, “there is no reason whatever to suppose that it is true; and it is, in fact, a less simple hypothesis”. To explain Russell’s argument, the conclusion that it is rational to believe that the external world exists follows from the premises that simplicity is a reason for believing in A, whereas there is not a reason to believe in B, although this latter may still be a conceivable possibility. This standpoint was also endorsed by a number of other intellectuals, specifically, the similar “Occam’s Razor” (Baker, 2011: ?) hold that if one theory is simpler than another, then it is rational to believe in it. Furthermore, the philosopher Douven pointed out that A and B “are not equally good explanations” (Douven, 2017: ?) because A is simpler than B. In other words, Russell is reasoning by abduction, which means making an inference to the best explanation, according to which, A is a better explanation than B because it uniquely has the feature of simplicity. Moreover, Russell employs the case of the cat’s hunger to exemplify his theory: the simpler explanation for the cat to be hungry is that the cat physically exists rather than being only a set of
