When science, art, literature, and philosophy are simply the manifestation of personality they are on a level where glorious and dazzling achievements are possible, which can make a mans name live for thousands of years. – Denis Diderot
Although a man may wear fine clothing, if he lives peacefully and is good, self-possessed, has faith and is pure and if he does not hurt any living being, he is a holy man. – Denis Diderot
There is no moral precept that does not have something inconvenient about it. – 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. – Denis Diderot
Science is out of the reach of morals, for her eyes are fixed upon eternal truths. Art is out of the reach of morals, for her eyes are fixed upon things beautiful and immortal and ever-changing. To morals belong the lower and less intellectual spheres. – Oscar Wilde, The Critic as Artist, 1891
