Final answer:
Albert Camus presents his absurdist philosophy in The Guest by demonstrating the inherent meaninglessness of life and by challenging the existentialist belief in creating meaning through individual actions.
Step-by-step explanation:
In Albert Camus's short story The Guest, he presents his absurdist philosophy by highlighting the arbitrary nature of the world and the isolation of the individual within it. He rejects the existentialist notion of building meaning through individual actions, which could be seen as Camus's refusal to embrace the existentialist idea that 'existence precedes essence.' Instead, Camus suggests that life has no inherent meaning, embracing the concept of the absurd - that humans naturally seek meaning in a world that inherently lacks it.
This is depicted through the protagonist's experience with an Arab prisoner and the realization of the inevitability of his isolation and the absurdity of his situation, underscoring an indifferent universe.
