Quote by Denis Diderot
When superstition is allowed to perform the task of old age in dulling the human temperament, we can say goodbye to all excellence in poetry, in painting, and in music.
Summary
This quote suggests that when people rely on superstition to pacify or numb their minds as they age, it hampers their ability to appreciate and create creative and beautiful forms of expression like poetry, painting, and music. It implies that superstition can hinder the development of human intellect, passion, and creativity, and therefore, individuals should seek to transcend superstition in order to nurture excellence in the arts.
