Here is today’s quiz question. Which master of exposition said this, and where?
After arguing for years, unconvincingly, that semantic value (properly understood) is not affected by substitution, I hit upon a brilliant, new, and completely successful, strategy: argue, instead, that semantic value is affected by substitution.
Here’s a hint: the quote occurs after in the context of a discussion of proper names.
(Upon reflection, that’s not much of a hint, is it?)
Post your guess as to who I’m quoting, in the comments form on this post. (You can post an informed answer too, if you like, but I suspect a guess would be even more fun.) The most interesting answer will receive a prize in the honest-to-goodness snail mail.
