His distancing, in how much critic, puts an end to the quest of the univocity and to the hope of to tell the truth quite, making here free more than libertarian. This article suggests pulling three teachings of its thoughts combined in <span style="text-decoration:underline;">Farewell to reason</span>. They will concern three expressions of the ways of the freedom developed in its work: the otherness, the plurality and the peculiarity.</p> </r2r:ml>
