 It has been argued that Wittgenstein’s later thought, though perhaps not overtly fideistic, nevertheless lends itself to fideistic interpretation. According to this interpretation, religion is a self-contained and primarily expressive enterprise, governed by its own internal logic or “grammar.” This view – commonly called Wittgensteinian Fideism – is variously characterized as entailing one or more of the following distinct (but arguably inter-related) theses: (1) that religion is logically cut off from other aspects of life; (2) that religious discourse is essentially self-referential and does not allow us to talk about reality; (3) that religious beliefs can be understood only by religious believers; and (4) that religion cannot be  criticized.[7]
