What does Albert Camus mean when one commits philosophical suicide? I was learning about him and the speaker spoke about this, however they didn't give a clear enough example of this.
For existential philosophy, failing to grapple with the paradoxes of death (in that it explicitly limits our ability to perceive the world in its totality) and the Real (that, because our perception is limited, we are unable to find universal knowledge about the world) constitutes a harm to our ability to live to our fullest (in that we live thinking that our lives are universal, when they can never truly be). It's somewhat paradoxical, that being unwilling to grapple with the problem of death constitutes suicide, but for Camus, philosophical suicide is the unwillingness to grapple with the very nature of life, and by this, never "truly live." Philosophical suicide in existential philosophy broadly is the Kierkegaardian leap of faith, Descartes' trust in God, and the analytic philosophers' assumption of universality.
