The quote "Who taught you all this, doctor?" by Albert Camus raises questions about knowledge, authority, and the origins of wisdom. It suggests an inquiry into the sources of a person's expertise, particularly in a medical context, where trust in a doctor's knowledge is paramount. This line evokes curiosity about how experience and learning shape one's understanding of life and suffering. The speaker's fascination highlights the complexity of human knowledge, often acquired through both formal education and personal experience.

Moreover, the quote signifies the importance of mentorship and the transfer of knowledge. It reflects on the relationships between teachers and students, indicating that no one is born with all the answers. Instead, wisdom is cultivated through interactions, challenges, and the sharing of experiences. Camus's words encourage a deeper consideration of how we learn and who we turn to for guidance, emphasizing the interconnectedness of human experience and the paths we take to gain insight into our lives and the world around us.
