Existential questions are fundamental inquiries about life, existence, and the nature of being. They often explore themes such as the purpose of life, the nature of reality, and the concept of free will. These questions can lead to deep philosophical discussions and are central to the field of philosophy. Common examples of existential questions include "What is the meaning of life?" and "Do we have free will?" These inquiries can arise in various contexts, including literature, psychology, and religion, prompting individuals to reflect on their beliefs and values.
