"Medieval crusaders believed that God and heaven provided their lives with meaning. Modern liberals believe that individual free choices provide life with meaning. They are all equally delusional."

This essay seems to be mostly posited to critique the belief in individual narrative- i.e. the idea that we are free individuals who have the will to choose rationally, as the idea of liberalism is based in.

While I'm down for that argument, the above passage is of particular confusion for me. If no external, nor internal force provides meaning to life, what is there? If the passage was to claim there is no meaning at all, why not just say that clearly?
