"It is a charte blanche, ready for receiving the inscriptions of sense; yet it behoves us carefully to observe, that it differs from a rasa tabula or a sheet of clean paper, in the following respect, that you may write on clean paper; that sugar is bitter, wormwood sweet, fire and frost in every degree pleasing and [sufferable?]; that compassion and gratitude are base; treachery, falshood, and envy noble; and that contempt is indifferent to us: Yet no human art or industry are able to make those impression on the mind."
