Mary Shelley

"No man chooses evil because it is evil; he only mistakes it for happiness, the good he seeks."

"nothing contributes so much to tranquilize the mind as a steady purpose"

"The labours of men of genius, however erroneously directed, scarcely ever fail in ultimately turning to the solid advantage of mankind."

"Invention, it must be humbly admitted, does not consist in creating out of void but out of chaos."
