As nothing does not change with the passage of time, philosophical thoughts will change with the situation of the times. In this sense, this study tries to argue that the modern liberty or autonomy deviated from the mythology of the theocentric society before modern times is another mythology. First, we will examine that the reason that the liberty of the modern subject is impossible, in other words, the autonomy of the modern individual subject is a mythology. It will be carried out by de-constructing the concept of liberty of Lock’s individual subject as the threshold of modern liberty [liberalism] in political sense, and by de-constructing the concept of Kant’s autonomy that constitutes the autonomy of the individual subject as philosophical principle. By the way, as the autonomy is the autonomy of the individual subject, the mythology of the autonomy is the mythology of the individual subject. So The mythology of the autonomy of the individual subject will also be exposed, if the individual subject is disclosed as the de-construction. Second, we will examine how the liberty of subject can be actually realized by comparing and criticizing the concept of the subject of liberalism and communitarianism, which are today sharply conflicted both in theory and in practice. Finally, across this process, and at the end of this process, we will be guided by the deconstruction theory, whether the autonomy that will comes after the mythology of the modern subject is (im)possible and how it is (im)possible if it is (im)possible. After all, by exposing that the individual subject is de-construction, new narratives to come will be provided for the subject’s place, namely the place of the mythology of the autonomy.
