"But in this we are much kinder to our sense than to our intellect; for in order to assist the former we use glasses and spectacles of all kinds adapted to our deficiency of sight, whereas in the latter we are so far from accepting the assistance of mental glasses or spectacles, that we often strain our mind's eye, even to blindness, and at the same time affirm that our sight is nothing less than perfect"
— Fielding, Sarah (1710-1768) and Jane Collier (bap. 1715, d. 1755)
