This is a serious challenge to the Modern conception of humans as rational beings who can bring about change in desired directions through the exercise of reason. Thus, reason does not enable us to see the world as it truly is and change it as we wish in a way that leads to progress. The concept of language games is crucial for many postmodern thinkers.
If we think through language and the use of language is thought itself, then what is perceived is indistinguishable from language use. The two cannot be separated because language governs interpretation, perception, and thought. To return to Wittgenstein's phrase, different people play and live in different "language games," meaning their languages cause them to see the world differently and conceptualize things differently from those in other language games. So, what does this mean for someone interested in politics?
In conclusion, this implies that whenever we attempt to understand the world, it is through language and interpretation because we cannot directly perceive reality outside of our language. This begins to suggest the possibility that one's own culture, society, or polity does not have universally "true" answers to the key questions of human existence. Our culture develops answers within its language game that make sense at a particular time for that culture. Everything is an interpretation of uncertain texts within different language games.
Certainly, this is a powerful argument. Many people disagree that language itself shapes our views of reality, and this argument must be taken seriously. Nevertheless, the idea of "language games," although just a small part of this book, is a thought-provoking concept that is well worth considering.
