Quote by Arthur Cayley
As for everything else, so for a mathematical theory: beauty can be perceived but not explained.
Summary
This quote suggests that just like in any other subject, the concept of beauty in mathematics is subjective and cannot be fully rationalized or justified. While individuals can appreciate the aesthetics of a mathematical theory, the essence of its beauty remains intangible and cannot be completely understood through logical explanation. Essentially, beauty in mathematics is a mysterious and personal experience, evoked by the elegance and harmony found within the theory.
