Or one can say that he is fat
and he is greedy, because our truth rule for "and" tells us that "Fa and Ga" is
going to be true only when Albert is fat and Albert is greedy. (Check that for
yourself.) And the word "and" can be iterated, that is, applied over and over
again, to make longer and longer sentences without letup: "Fa and not Fb";
"Fa and not Ga and Fb and not Gb"; "Fa and Ga and not Fb and Gb and Fa
and not Fb"; and so on forever. (Of course the later sentences will be repeti-
tious, since Oafish has such a small lexicon, but even the most repetitious
sentences are still grammatical and have perfectly clear truth conditions.)
So, just from this trifling little truth definition we have already got infi-
nitely many grammatical sentences, and we have projection rules that tell us,
no matter how long a sentence is, the condition under which that sentence is
true. Armed with this, we could encounter any novel sentence of Oafish, even
