Wittgenstein is usually taken to have held that the use of a term is not mentally constrained. That is utterly wrong. A use of language unconstrained by meaning is attributed by him to "meaning-blind" or "aspect-blind" creatures, not to us. We observe meaning when an aspect dawns on us; meaning is the impression {Eindruck) of a term as fitting something; hence, unhke pain, it cannot stand alone. That is a mentalistic theory of meaning: use is determined by images {Vorstellungen) that play semantic roles in virtue of their aesthetic properties. Although a term may be arbitrarily interpreted, aesthetic reasons determine which interpretation be seen as right for it.
