The true knowledge or science which exists nowhere but in the mind itself, has no other entity at all besides intelligibility; and therefore whatsoever is clearly intelligible, is absolutely true.

This quote by Ralph Cudworth explores the nature of knowledge and truth from a philosophical perspective. By stating, “The true knowledge or science which exists nowhere but in the mind itself, has no other entity at all besides intelligibility,” Cudworth emphasizes that genuine knowledge resides in the mind and intellect, rather than solely in external objects. The quote suggests that intellectual comprehension and clarity are central to understanding reality.

Cudworth further asserts a direct link between intelligibility and truth. “Therefore whatsoever is clearly intelligible, is absolutely true” implies that if something can be fully comprehended and understood by reason, it can be considered objectively true. This reflects a rationalist viewpoint, where clarity of thought and logical comprehension are the ultimate criteria for truth.

The quote originates from Ralph Cudworth, a 17th-century English philosopher and theologian, associated with the Cambridge Platonists. Cudworth’s work often focused on reason, morality, and the intellectual foundations of knowledge, emphasizing the mind’s capacity to grasp immaterial truths through rational reflection rather than sensory perception alone.

Ultimately, the quote touches on themes of knowledge, intelligibility, and truth. It suggests that true understanding is a mental and intellectual achievement, where the mind itself serves as the locus of knowledge, and clarity of comprehension guarantees the veracity of what is known, highlighting the profound relationship between reason and truth in human cognition.
