Abstract

Traditional philosophy relies heavily on the use of rational intuition to establish theses and conclusions. This essay takes up the matter of intuition and argues for a stunning conclusion: appeal to rational intuition is epistemically justified only if a form of foundationalism is true. This type of foundationalism is the thesis that there is at least one proposition whose justification depends on nothing other than itself. The article also argues that unless we can establish that some intuitions are justified, philosophy as an enterprise that provides non-empirical knowledge is impossible. Not to put too fine a point on it then: philosophy is possible only if foundationalism is true. Whether this should be construed as the strongest possible defense of foundationalism, or the greatest objection to the pretensions of philosophy is left to the reader.
