“... I want to live and be happy. I believe that we cannot be one or the other by pushing the absurd to all its consequences. I am like everyone. To feel liberated, I sometimes wish death on my loved ones, I covet the wives forbidden to me by the laws of family and friendship. To be logical, I should then kill or possess. But I judge that these vague ideas are unimportant. I everyone tried to put them to reality, we could neither live nor be happy.”
—Albert Camus (1913–1960)
“Life is not a series of gig lamps symmetrically arranged; life is a luminous halo, a semi-transparent envelope surrounding us from the beginning of consciousness to the end.”
—Virginia Woolf (1882–1941)
