The dynamic and range of polemics among social scientists can testify to branches of science vivacity and progress. Especially when those polemics’ implications are not closed inside the academic world, but they influence social and political life. This situation refers to liberal-communitarian debate. In 1956 Peter Laslett in Philosophy, Politics and Society announced the death of political philosophy. This subdisciplines’ end, as well as the whole philosophy, was connected with the rudimental modern world’s split in the humanistic and scientific vision. The collapse and rot of the political philosophy (Leo Strauss) reached their culmination in the logical positivism and its derivatives’ supremacy time. This neopositivism had been looking for the clear criteria of the science and metaphysic’s demarcation and, at the same time, had tried to exclude metaphysic outside the legitimated reflection.
