Abstract

Words are changing their meanings in natural language. Even if their extension remains the same, their intension does not, and a sentence often alters in meaning. Whenever such a phenomenon occurs, what is happening in us? Contextualism offers some effective explanation, but is unable to see why even the meaning of a predicate changes, why our “thought” expressed in a sentence undergoes substantial transformation, or why the world changes its "meanings" for us. I explore a theory of semantic determination to describe and explain ways our own selves and the world simultaneously change. This theory consists of such elements as perspective extension, epistemic restriction by our “mental walls,” and role-playing volition, all of which together constitute a multilayered standpoint.
