The sun really does have the appearance of being the size of a dinner
plate, even to someone who knows that it is a huge fusion process; it is
not reducible to one's "mistake," but that does not mean that it is a
"false" appearance. (Playing with the word "true," All appearances are
true appearances. It is a tautology but apparently a needed one to
affirm that an appearance of x is an appearance of x.)
