Ever since studying French in college some 45 or more years ago I have loved the works of Albert Camus and, in particular, his 1942 novel L’Etranger (The Stranger/The Outsider).
There is a philosophical tension in Camus’ philosophy of life. On the one hand, life is absurd, irrational, futile, and manifestly unjust, but on the other hand we are rational beings—at least in potentiality—and therefore not absurd. Additionally, it is possible for us to be happy even in a world of tragedy, irrationality, manifest injustice, and suffering.
