The teachings of Catholicism indicate a road a truth and a promise of happiness. Liberalism appears when modern man wants to assume autonomously his philosophical opinions, his political preferences and his economic decisions. Amid these two great alternatives, the author proposes a permanent resistance to the "explanations" that self-complacent Catholicism and liberalism can offer. He suggests trying the essence of Christianity, despite its simplification in traditional theology. But he also recommends opposing the complacency of democracy and of capitalism-socialism, so as to recover the belief in the goodness of the world and resisting their simplifications, such as "neo-liberalism" and permissiveness.
