A Study on Philosophical Intuition and Thought Experiment: Kripke's Critical encounter with Reductive Physicalism

In philosophy, many reflections and categories were the result of intuition and thought experiments. Intuition is defined as direct, immediate, and non-inferential knowledge accompanied by a sense of certainty. The thought experiment has always been a source of new insights by imagining possible situations to demarcate concepts and revise common philosophical theories. Metaphysicians usually have consensus on the informativity of intuition, but in the analytical tradition, there are severe challenges in dealing with this type of knowledge. On the other hand, some contemporary philosophers believe that the thought experiment induce the unjustified and unacceptable results in the mind of audience. In this article, by referring to some aspects of Kripke's thought, we show that his use of intuition and thought experiments in his critique of radical physicalism is defensible. By distinguishing between fixing the referent of the mental state and the physical phenomenon, Kripke has been committed to the theory of property dualism, which is a critical approach to physicalism in the realm of philosophy of mind.
