Pietà
Pietà is a collection of essays by the Hungarian-Swedish biologist, George Klein, first published in Sweden in 1989. It includes nine essays by Klein, several touching broadly on the theme of whether life is worth living. The introduction opens with a quote from Albert Camus in The Myth of Sisyphus (1942): "There is but one truly philosophical problem, and that is suicide. Judging whether life is or is not worth living amounts to answering the fundamental question of philosophy."
