The Story of My Mind; Or, How I Became a Rationalist

A philosophical memoir likely written in the early 20th century. The work recounts the author's journey from a devout upbringing as a Calvinist to his eventual embrace of Rationalism. Central to the narrative is Mangasarian's introspection on faith, reason, and his critique of dogmatic beliefs, aimed at encouraging his children—and potentially his readers—to seek their truths. The beginning of the book introduces Mangasarian’s personal context, dedicating the work to his children while sharing how his experiences, particularly his upbringing and early religious commitments, shaped his thoughts. He reflects on his childhood, the pressures of preparing for the ministry, and the awakening of his rational thinking prompted by encounters that challenged his beliefs. Mangasarian describes vivid moments that fueled his intellectual conflict, particularly a harrowing experience during a journey in Asia Minor where reliance on divine aid led to a moment of crisis, ultimately contributing to his shift towards rational thought over traditional Christian beliefs. The autobiographical elements set the tone for a deeper exploration of faith, skepticism, and the value of inquiry over inherited dogma.
