Jean-Paul Sartre, a French philosopher who explored the ideas of our essence vs. our existence. He saw human beings as physical and emotional characters. Meaning - not only can we eat, sleep, and breathe as a functional person but we can feel. We are able to admire a beautiful day and feel the sunshine and live! Sartre believed that yes - we are brought in to this world as just a small baby who eats and sleeps to survive. But as we grow and we make choices, these choices are what lead us to truly embrace our essence.
