A Private Language Argument Against Unitarianism
Nature is semiotic. The intelligible, effable, and teleological characteristics of creation, and the alethic, aesthetic, and moral values it intrinsically possesses, are best explained by the existence of a non-unitarian God. The One, Eternal God “spoke” creation into existence such that it is suffuse with meaning. Thus, all things are pros hen analogically comparable insofar as they reflect, to varying degrees, ipsum esse subsistens. “For from the greatness and the beauty of created things their original author, by analogy, is seen” (Wisdom 13:5). Nature did not gain this meaning with the advent of other intelligent beings. The meaning was embedded in nature by its “author” from eternity. Yet, there are no private languages. So, from eternity, the analogical meaning communicated ad extra to each created thing must be grounded in a kind of non-private ad intra divine communication, which is impossible on the supposition that God is but one person.
