Step-by-step explanation:
According to Jean-Paul Sartre, consciousness is described as the awareness of being and the experience of the present moment. He believes that there is no self that exists through time, but only the eternal present where we are aware of our surroundings and experiences. Sartre categorized real things into two types: being-for-itself, which is conscious and free, and being-in-itself, which is non-conscious. Consciousness allows us to be aware of internal stimuli such as emotions and thoughts, as well as external stimuli like sights and sounds.
