Hamlet displays existential attitudes like distress over the absurdity of the world. He contemplates the meaning of existence in his "To be or not to be" soliloquy. Throughout the play, Hamlet strives to define what it means to be an authentic, responsible human being. He realizes existence precedes essence - that he can create his own identity through his choices and actions. Shakespeare engages with complex existential themes that have continued relevance for understanding the human condition.
