I'll stick with books by Slavoj Žižek.

"The Italian philosopher Giorgio Agamben said in an interview that 'thought is the courage of hopelessness' ─ an insight that is especially pertinent for our historical moment, when even the most pessimistic diagnosis as a rule finishes with an uplifting hint at some version of the proverbial light at the end of the tunnel. The true courage is not to imagine an alternative, but to accept the consequences of the fact that there is no clearly discernible alternative: the dream of an alternative is a sign of theoretical cowardice; it functions as a fetish that prevents us thinking through to the end the deadlock of our predicament. In short, the true courage is to admit that the light at the end of the tunnel is most likely the headlights of another train approaching us from the opposite direction."
