No one has dwelled into the issue of suicide more deeply that Albert Camus. Albert Camus believed that the fundamental question was, "Is there any reason not to commit suicide?" Here are some quotes about Camus that would come to some use.
"There is but one truly serious philosophical problem, and that is suicide. Judging whether life is or is not worth living amounts to answering the fundamental question of philosophy. All the rest -- whether or not the world has three dimensions, whether the mind has nine or twelve categories -- comes afterward. These are games; one must first answer."
-- Albert Camus from An Absurd Reasoning
Albert Camus once said, "The only way to deal with an unfree world is to become so absolutely free that your very existence is an act of rebellion."
To quote Brooke Noel Moore and Kenneth Bruder:
"Camus regarded suicide as unacceptable. Suicide, he thought, is a kind of weakminded acquiescence to an unjust destiny. Camus believed, perhaps paradoxically, that by struggling against the Sisyphean fate to the end, by rebelling against the absurdity and tragedy of life, it is possible to give life meaning and value. His position indeed is that only through this struggle with an absurd world can the individual achieve fulfillment, solidarity with others, and 'a brief love of this earth.'"
