"It's no good having one without the other"

In September of 1968, in what he jokingly termed “E. Gorey’s Great Simple Theory About Art,” Gorey wrote these Yodaesque words:

“This is the theory ... that anything that is art ... is presumably about some certain thing, but is really always about something else, and it’s no good having one without the other, because if you just have the something it is boring and if you just have the something else it’s irritating.”
