“The language of categories is affectionately known as "abstract nonsense," so named by Norman Steenrod. This term is essentially accurate and not necessarily derogatory: categories refer to "nonsense" in the sense that they are all about the "structure," and not about the "meaning," of what they represent.”

“Nonsense remains nonsense even when we talk it about God.”

“That is the bitterness of art: you see a good effect, and some nonsense about sense continually intervenes.”

“There are two kind of men,' said Ka, in a didatic voice. 'The first kind does not fall in love until he's seen how the girls eats a sandwich, how she combs her hair, what sort of nonsense she cares about, why she's angry at her father, and what sort of stories people tell about her. The second type of man -- and I am in this category -- can fall in love with a woman only if he knows next to nothing about her.”

“We never choose which words to use, for as long as they mean what they mean to mean, we don’t care if they make sense or nonsense.”

“Many have referred to [Lewis] Carroll's rhymes as nonsense, but in my childhood world — Los Angeles in the '50s — they made perfect sense.”
