The young traveler in Naguib Mahfouz's "Palace of Desire" appears to be on a significant and protracted journey. He has embarked on a metaphorical train, represented by Auguste Comte's philosophical ideas, where each station reflects different ideologies. Initially, he stops at the theology station, which promotes a blind faith devoid of inquiry or critical thinking, reinforcing the idea of acceptance without investigation.

As he continues his journey, he transitions to the realm of metaphysics, which encourages skepticism and questions established beliefs, instead advocating for a deeper exploration of existence. Ultimately, he approaches realism, beckoned by the call to open his eyes and embrace reality. This journey highlights the conflict between belief systems and the pursuit of truth, illustrating a struggle between faith, questioning, and the acceptance of reality.
