Not that the incredulous person doesn't believe in anything. It's just that he doesn't believe in everything.
Umberto EcoTo play the trumpet, you must train your lips for a long time. When I was twelve or thirteen I was a good player, but I lost the skill and now I play very badly. I do it every day even so. The reason is that I want to return to my childhood. For me, the trumpet is evidence of the sort of young man I was.
Umberto EcoIf two things don't fit, but you believe both of them, thinking that somewhere, hidden, there must be a third thing that connects them, that's credulity.
Umberto EcoYou always want someone to hate in order to feel justified in your own misery. Hatred is the true primordial passion. It is love that's abnormal. That is why Christ was killed: he spoke against nature. You don't love someone for your whole life - that impossible hope is the source of adultery, matricide, betrayal of friends ... But you can hate someone for your whole life - provided he's always there to keep your hatred alive. Hatred warms the heart.
