Every branch of human knowledge, if traced up to its source and final principles, vanishes into mystery.

The quote by Arthur Machen reflects on the inherent mystery underlying all human knowledge. Machen suggests that no matter how much we study or analyze a particular field, when we trace it to its source or fundamental principles, we encounter uncertainty and the unknown. This observation highlights the limits of human understanding and the enduring presence of the unexplained in even the most rigorous disciplines.

Machen emphasizes that knowledge, while seemingly concrete and structured, ultimately rests on assumptions and foundations that are not fully comprehensible. The quote invites reflection on the philosophical and metaphysical dimensions of inquiry, suggesting that the pursuit of truth inevitably confronts questions that resist complete resolution. This acknowledgment of mystery adds depth and humility to the pursuit of understanding.

The origin of this statement comes from Machen’s work as a writer and mystic in the late 19th and early 20th centuries, known for his explorations of the supernatural, the unknown, and the limits of perception. His writings often blend literary imagination with philosophical inquiry, challenging readers to consider the hidden or ineffable aspects of reality that lie beyond empirical observation.

In essence, the quote underscores that while humans strive for knowledge, the ultimate sources and principles of reality remain elusive. Machen encourages a recognition of the mysterious nature of existence, reminding us that the pursuit of understanding is as much about grappling with the unknown as it is about acquiring facts or explanations.
