Epistemological Implications of Rejection of Private Language

One of the most important and novel philosophical issues proposed by Wittgenstein in his late stage of thought and in his influential book Philosophical Investigations is the issue of private language. This issue is so important that one can say the epistemology of second half of twentieth century is entirely under its influence. Wittgenstein believes that the only way to get rid of epistemological and semantic skepticism is the rejection of private language. Furthermore, the problem of other minds, which has been an insoluble problem due to acceptance of the theory of private language, becomes fundamentally dissolved by rejecting the private language. While other solutions to the problem of other minds such as the argument from analogy and behaviorism suffer from many problems.
