Peirce, 1893:

There are those who believe in their own existence, because its opposite is inconcievable; yet the most balsamic of all the sweets of sweet philosophy is the lesson that personal existence is an illusion and a practical joke. Those that have loved themselves and not their neighbors will find themselves April fools when the great April opens the truth that neither selves nor neighborselves were anything more than mere vicinities; while the love they would not entertain was the essence of every scent.
