A Moorean fact, in the words of the late David Lewis, is ‘one of those things that we know better than we know the premises of any philosophical argument to the contrary’. Lewis opens his seminal paper ‘Elusive Knowledge’ with the following declaration.

From time to time philosophers and scientists have made sensational, provocative claims that certain things do not exist or never happen that, in everyday life, we unquestioningly take for granted as existing or happening. These claims have included denying the existence of matter, space, time, the self, free will, and other sturdy and basic elements of our common-sense or naïve world-view. Around the middle of the twentieth century an argument was developed that can be used to challenge many such skeptical (...) claims based on linguistic considerations, which came to be known as the Paradigm Case Argument ...

Flew strongly defends a compatibilist thesis in the free will debate before going on to totally object to theistic libertarianism. His objections basically rely on his compatibilism embracing the notion of agent causation, which is not very common in compatibilist theses. Since he is a strong proponent of ordinary language philosophy, he also holds that linguistic analyses can certainly solve the free will problem as well as many other problems of philosophy. In doing so, he first uses the paradigm cases (...) based on our common sense experience and then assumes the verity of principle of alternative possibilities. This study attempts to show, on the one hand, that there are some serious difficulties in both his justification of compatibilism and his objections to theistic libertarianism, and on the other hand, that he cannot easily defend both at the same time.

The argument from illusion/hallucination have been proposed many times as supporting the strong conclusion that we are always perceiving directly sense-data. In Sense & Sensibilia, Austin argues that this argument is based on a “mass of seductive (mainly verbal) fallacies”. In this paper, I argue that Austin's argumentative moves to deconstruct the argument from illusion is better understood if they are seen as due to his implicit commitment to some disjunctivist conception of perception. His considerations should be taken as a (...) depth discussion about how to conceive perception. If we conceive the perceptual capacity disjunctively, even the weaker conclusion that we sometimes perceive sense-data does not hold. In response to Austin, Ayer claimed that the strong conclusion of the argument from illusion could be sustained by the method of the possibility of error. I argue that this method alone does not sustain that conclusion and the controversy turns back to the conflict between different conceptions of perception. The argument from illusion is philosophically interesting by putting in evidence the problem of how the perceptual capacity should be articulated and conceived. Although matters of fact are relevant to this question, they alone do not decide it. (shrink)
