And you that sought for magic in your youth but desire it not in your age, know that there is a blindness of spirit which comes from age, more black than the blindness of eye, making a darkness about you across which nothing may be seen, or felt, or known, or in any way apprehended (Lord Dunsany, The King of Elfland’s Daughter)
