The Epistemic Value of Intuition in Philosophical Methodology
Quick fact
In a famous survey, a majority of philosophers reported being intuitionists, yet experimental studies have shown that people's intuitions about identical thought experiments can shift dramatically depending on culturally specific factors, such as whether a scenario is framed in terms of a 'moral' versus a 'conventional' rule.
Why this is interesting
Have you ever had a strong feeling that a philosophical thought experiment is right, without being able to explain why? Philosophers rely on such intuitions as evidence—but can they really ground knowledge?

Understanding The Epistemic Value of Intuition in Philosophical Methodology
Intuition, in philosophy, is not a vague hunch but a specific kind of mental state: a seeming or intellectual seeming that a proposition is true, often used in thought experiments like the Gettier cases or the Trolley Problem. For example, when you consider a Gettier case, you have a compelling intuition that the subject does not know, even though all the JTB conditions are met. This intuition is treated as a data point, a piece of evidence about the nature of knowledge. Philosophers use intuition to test theories: if a theory conflicts with a strong intuition, that is a mark against the theory. Intuitions are not based on empirical observation or explicit reasoning; they are spontaneous and non-inferential. They are often considered a priori, meaning they do not rely on sensory experience, and they are supposed to provide direct access to truths about modality, metaphysics, ethics, and other philosophical domains.
A deeper explanation
The epistemic value of intuition hinges on whether intuitions can confer justification. The leading view, rationalism, holds that some intuitions are reliable because they are products of a cognitive faculty that tracks truth, much like perception tracks the empirical world. Justification arises when a belief is based on a reliable intuition, in the absence of defeaters. However, this raises the calibration problem: we lack a clear external standard to check intuition's reliability, unlike perception which can be tested against the world. Moreover, intuitions vary across persons and cultures, as shown by experimental philosophy, creating disagreement and undercutting their evidential force. The collapse of the expertise defense—that philosophically trained intuitions are more reliable—challenges the idea that philosophical intuitions are privileged. Yet, without intuition, philosophical inquiry would grind to a halt: we would have no way to evaluate thought experiments, test hypotheses, or reason about abstract truths like morality or necessity. The epistemic value of intuition is thus both central and contested: it is a crucial source of philosophical evidence, but its justification must be secured through coherence, peer scrutiny, and calibration against other methods.
