Summary
This quote implies that insanity, or madness, can sometimes be the result of an exceptionally sharp and perceptive mind that is overwhelmed or burdened with excessive mental tasks. It suggests that when a highly intelligent or rational mind is subjected to extreme pressure, stress, or an overwhelming amount of information, it may seem irrational or insane to others because of the difficulties in coping with the intense mental strain. In this context, insanity is portrayed as a response to an overloaded and overworked mind, rather than a sign of inherent irrationality.
