On Communication and Definitions

In the comments of the post called, "Philosophy of Religion" and "Theology": What's the Difference?, r.j.marvin and I have been having an interesting conversation on communication. A concern was expressed: when individuals engage in dialogue, can they rationally discuss topics where the definitions of major points of contention are unclear? For example, assume that an atheist, a Calvinist, and a Muslim were engaged in a dialogue about God. The atheist remarks that the idea of God is internally contradictory, due to the nature of omnipotence and omni-benevolence. The Calvinist remarks that God has mysteries that cannot be explained, such as the nature of the trinity, but is not internally contradictory. The Muslim remarks that the idea of God is not internally contradictory and, while mysterious, has no apparent contradictions. It seems like all three of these discussants have different definitions of God. Can they, thus, rationally discuss the topic?

First, I will argue why they can. Second, I will defend against reasons why they allegedly could not by addressing the initial quandary.

If it were true that individuals can maintain distinct definitions of words without the possibility of harmonization, definitions would be meaningless and devoid of substance, because they would not have any references. Imagine if I defined "Quarorglewoggle" as "Gltheltic-giborglewoggle". If you asked me to define "Gltheltic-jiborglejiggle", I would continue using nonsense words with no real-world references, and would eventually come back to "Quarorglewoggle". We would thus not be able to have any legitimate knowledge of what is being communicated. In other words, if the skeptical concern is legitimate, we would not have legitimate understanding of the references of others' words. Since we do have legitimate understanding of the references of others' words (given that you are reading this), it is not the case that the skeptical concern is true (and, thus, the skeptical concern is false), at least about some words.

"Some words", however, is very different from "all words" (there's a puzzle for you). Could there exist a word that, through the method I outlined above, can be circularly defined in nonsensical terms? Yes-- consider "quarorglewoggle". Here's my question: we have the word "quarorglewoggle". Is there actually a reference of the word? In other words, we can imagine "quarorglewoggle" (the word); can the speaker imagine quarorglewoggle (the reference of the word)? If not, they are either deceiving their fellow discussant (but we're assuming that they're acting in good faith, so this isn't an issue), or there is actually something that the word refers to. There exist many properties that, as we have already established, are not nonsensical (in that they can be meaningfully defined). Each of these properties either do or do not relate to the definition of the word. For example, if I defined the "best flavor of icecream" as "that particular taste of ice cream that is most pleasing to the taster", the property of being "Cherry-Vanilla" does not relate to the definition of the word-- merely the instantiation (the carrying-out) of the definition.

Back to our initial quandary. If a Calvinist claims that the definition of God, via the Trinity, is mysterious but not contradictory, we should tell him/her that they are mistaken. The Trinity is no more a part of the definition of God than Cherry-Vanilla is part of the definition of the best flavor of ice-cream; it's part of the instantiation. The Muslim's claim is coherent. The Atheist's claim, that the definition of God entails a contradiction (omni-benevolence and omnipotence) sets us up for a great topic that could be discussed, but makes the same mistake as a Calvinist. The Greek gods were certainly not omnibenevolent, nor were they omnipotent, and yet they are still referred to as gods. The Atheist concern is with a specific instantiation of the definition of God, not with the definition of God itself.

In conclusion, we must be careful when we distinguish between definitions and instantiations of definitions. There are no true contradictions in reality (assertion on my part, feel free to challenge it), and thus no definition will be contradictory. Instantiations of definitions, however, may be. The definition of "contradiction" is not contradictory, but all instantiations of "contradictions" are, necessarily, contradictory.
