On May 17, 2017, Jonathan Fanton introduced a discussion on visual perception, entitled “How Do We See?” Ken Nakayama moderated the discussion between Charles Gilbert and Dale Purves.
The discussion served as the 2054th Stated Meeting of the American Academy of Arts and Sciences.
Good evening. I am Jonathan Fanton, President of the American Academy. It is my pleasure to welcome you and to call to order the 2054th Stated Meeting of the American Academy of Arts and Sciences.
Our topic this evening is “How do we see?” As you can imagine, questions about how vision works have been ever-present throughout the life of the Academy. In fact, an issue of the Academy’s Memoirs from 1809 contains a communication from Peres Fobes, a Massachusetts clergyman elected to the Academy in 1780, entitled “A Curious Phenomenon of Vision.” His letter describes the case of a 46-year-old man named Pierce who had “a kind of ulcer collected in his head,” which confined him to his home with weak eyesight and extreme sensitivity to light.
One night the ulcer broke, and Mr. Pierce awoke free of pain, feeling well and composed. He arose and went to look out a window, and, as Reverend Fobes described,
“to his great surprise [Pierce] saw, at a place called Reed’s ware-house, near the ferry, at the distance of near two miles, a cart and yoke of oxen. He could plainly discern the color of the oxen, the rounds in the cart, the stones on the beach, and even the courses and joints in the shingles on the ware-house. This extraordinary degree of acute, telescopic vision continued for about one hour; after which his sight returned to its usual state.”
The letter goes on to vouch for Mr. Pierce’s character and judgment.
