Quote by Michel de Montaigne
Stubborn and ardent clinging to one's opinion is the best proof of stupidity.
Summary
This quote suggests that rigidly sticking to one's own opinions without considering alternative perspectives is indicative of a lack of intelligence. It argues that being stubborn and fervently holding onto one's beliefs without open-mindedness or willingness to adapt can hinder personal growth and understanding. It implies that intellectual growth is achieved through a willingness to consider diverse viewpoints and critically evaluate one's own beliefs. Therefore, this quote implies that being open to new ideas and being flexible in one's thinking is a better approach than stubbornly clinging to fixed opinions.
