Memories, Dreams, Reflections
Saul Steinberg in The New York Review of Books issue dated August 15, 2002, page 32:
“The idea of reflections came to me in reading an observation by Pascal, cited in a book by W. H. Auden, who wrote an unusual kind of autobiography by collecting all the quotations he had annotated in the course of his life, which is a good way of displaying oneself, as a reflection of these quotations. Among them this observation by Pascal, which could have been made only by a mathematician….”
Pascal’s observation is that humans, animals, and plants have bilateral symmetry, but in nature at large there is only symmetry about a horizontal axis… reflections in water, nature’s mirror.
This seems related to the puzzling question of why a mirror reverses left and right, but not up and down.
The Steinberg quote is from the book Reflections and Shadows, reviewed here.
