 Expressive communication, I will argue, exhibits features that foreshadow significant aspects of linguistic communication. In its domain, we can identify legitimate natural precursors of meaningful linguistic communication. (For present purposes, by ‘legitimate natural precursors’, I mean behavioral interactions that at least: a. can be found in the natural world; b. go beyond Tomasello’s mere ‘communicative displays’; c. do not depend on crediting the relevant creatures with language-like propositional thought or post-Gricean communicative intentions, and; d. exhibit features that foreshadow important semantic and pragmatic features of linguistic communication so in that sense are proto-semantic and proto-pragmatic.)
