On the Essence of Thought Experiments

A Neo-Aristotelian and Phenomenological Approach

Abstract

Thought experiments feature prominently in both scientific and philosophical methods. In this paper, I investigate two questions surrounding knowledge in the thought experiment process. First, on what implicit knowledge do thought experiments rely? Second, what provides epistemic justification for beliefs acquired through the process? I draw upon neo-Aristotelian metaphysics and Husserlian phenomenology to argue that essence is the object of implicit knowledge that anchors the imagined possibilities involved in thought experiments to the actual world, and that this essentialist knowledge enables the possibility of prima facie justification being conferred by the phenomenological givenness of thought experiment scenarios.
