João Espada is the director and founder of the Institute for Political Studies at the Catholic University of Portugal, where he is professor of political studies. In this interview, hosted by Luis Figueroa, João Espada defines the western tradition and mentions the main attacks directed at free societies in the 21st Century. He invites students to challenge politically correct ideas and to defend the liberty and dignity of every citizen. He analyses how individual liberty and responsibility can be perceived as a burden because of the consequences over the choices one makes in life. At the end, he expounds how the lack of critical thinking can be a serious reduction of our intelectual horizons.
