Remarks like the last may have thrown off readers like Winter. These remarks do not mean that signs have no effect on the mind, nor do they mean that every langnage game is an island without connections to the rest of langnage. If this were so, one could never learn a language. Rather, passages like this are attempts to locate Wittgenstein's purpose: He is attempting to work out a theory of meaning from a logical point of view, one that does not depend upon any particular empirical stimulus to account for its function. He is not denying reality to psychological effects; he is denying they have any necessary role in meaning.

DEFINE: Clarifies Wittgenstein's logical theory of meaning: it works without dependence on empirical/psychological stimulus, though without denying such effects exist.
