What is the main conflict in The Myth of Sisyphus and Other Essays by Albert Camus?

The Myth of Sisyphus is a collection of essays written over the course of about twenty years that revolve around the subjects of freedom from ideology and meaning and living life to the fullest degree. The title essay, which makes up the majority of the collection, investigates these concepts in an abstract, philosophical manner, while the rest of the essays are illustrations of the principles contained in the first.
