Human knowledge is dark and uncertain; philosophy is dark, astrology is dark, and geometry is dark.

John Jewel’s quote reflects his perspective on the limitations and uncertainty of human knowledge. By stating that philosophy, astrology, and geometry are all "dark," he emphasizes the idea that human understanding of the world is inherently unclear and filled with mystery. The use of the word "dark" suggests that these areas of knowledge, despite being pursued for centuries, still harbor significant gaps and uncertainties, leaving much to be questioned and explored.

Jewel’s remark also suggests a critique of intellectual pursuits in general, implying that no field of human study offers absolute certainty or clarity. While philosophy grapples with questions of existence, morality, and knowledge, and astrology deals with the interpretation of celestial bodies, both are often seen as speculative and difficult to substantiate. Even geometry, a mathematical field grounded in logic and proof, is labeled "dark" here, possibly pointing to the limits of human comprehension in fully understanding abstract concepts or the complexities of the universe.

The quote highlights the humility that Jewel suggests should accompany our pursuit of knowledge. Even fields that seem grounded in reason or science are not immune to doubt or confusion. This reflects a more skeptical view of human intellectual achievement, urging caution in the belief that we can ever fully understand the mysteries of the world.

The origin of this quote comes from John Jewel’s work as a theologian and bishop in the 16th century. Jewel was known for his involvement in the Church of England and his emphasis on faith over human reasoning. His comments likely reflect the theological debates of his time, where religion and philosophy often clashed, and he questioned whether human intellectual endeavors could truly lead to enlightenment without the guidance of divine knowledge.
