Mary Wollstonecraft Shelley said this quote

Oh, had I, weak and faint of speech, words to teach my fellow-creatures the beauty and capabilities of man's mind; could I, or could one more fortunate, breathe the magic word which would reveal to all the power, which we all possess, to turn evil to good, foul to fair; then vice and pain would desert the new-born world!It is not thus: the wise have taught, the good suffered for us; we are still the same; and still our own bitter experience and heart-breaking regrets teach us to sympathize too feelingly with a tale like this.
