In Being and Nothingness, Sartre discusses the concept of nothingness and its role in his philosophical thinking. He argues against the idea that imagination involves the presence of mental images and instead proposes that imaginative activity requires a radical break with the world and a relationship to unreal objects . Sartre's ontology in Being and Nothingness is compared to the medieval understanding of transcendentals, and his universal predicate of 'the not' is seen as an atheistic transcendental signifying the non-being of God . Sartre also explores the concept of otherness and the being-for-itself's fundamental shaping by its relationship with others, using examples such as the waiter and named individuals like Pierre to represent the presence of Others in his philosophy .
