That everyone has some privileged access to some information is trivially true. The doctrine of privileged access is that I am the authority on all of my own experiences. Possibly this thesis was attacked by Wittgenstein (the thesis on the non‐existence of private languages). The thesis was refuted by Freud (I know your dreams better than you), Duhem (I know your methods of scientific discovery better than you), Malinowski (I know your customs and habits better than you), and perception theorists (I can make you see things which are not there and describe your perceptions better than you can). The significance of this rejected thesis is that it is the basis of sensationalism and thus of all inductivist and some conventionalist philosophy.
