Human suffering is a complex phenomenon that can manifest physically or psychologically. As the negative valence of affective phenomena, with the positive being pleasure or happiness, human suffering could easily be interpreted as something to avoid. Sartre explored existential aspects of human suffering in Being and Nothingness. Examining each occurrence of the word suffering in that work provides a basis for understanding the roles Sartre assigned to it within the human experience and consequently provides a more nuanced appreciation of this (...) complex phenomenon. An electronic copy of Being and Nothingness was searched for all occurrences of the word suffering (N = 50), tabularized using the Key Word In Context (KWIC) approach at the sentence level, resulting in 40 sentences for thematic analysis. That analysis resulted in 5 themes, showing the complexity of suffering in Sartre’s major philosophical work and suggesting that suffering is quintessentially human, unavoidable, and potentially liberating.
