Much of the way that people write and speak in English makes heavy use of the various different forms of the verb ‘to be’ – for example, count how many sentences use the words ‘is’, ‘am’, ‘are’, ‘were’ (etc). Some thinkers criticise this pattern, saying that it promotes a kind of mental laziness or imprecision: we say “the sky is blue”, but what can that ‘is’ mean there? Better (more precise) to say “the sky appears blue”.
Around 1965, David Bourland proposed a new dialect of English – E-prime, or E’ in mathematical notation, short for English-Prime – based around the mental discipline of deliberately avoiding all of the forms of ‘to be’. Instead of saying “I am a lawyer”, say “I answer legal questions, I write contracts, I represent people in court”; by saying precisely what you actually do you are obliged to examine exactly what “being a lawyer” means. Or consider the old ditty:
Roses are red,
Violets are blue.
Honey is sweet,
And so are you.
In E-prime, we might instead write:
Roses look red,
Violets look blue.
I like honey,
And I like you.
You can find further examples of E-prime in the books of the psychologist Albert Ellis or science-fiction author David Gerrold, each of whom wrote several books in an E-prime style.
This seems to me to be a viable explanation of “alignment languages” in D&D, not that they are actually separate languages, but that they are “mental disciplines” of talking or writing using certain forms and avoiding others. The idea of a dialect built upon such precision sounds like something that could mark out Lawful-Neutral types.
It also reminds me of the pop-psychology therapy idea of using an “active voice” and avoiding nominative forms. So instead of saying “you are an idiot”, saying “I feel frustrated when you do that”. They share a feeling of saying “me me me” all the time; I feel frustrated, the sky looks blue to me. All this self-centric talk would suit chaotic alignments too. Imagine Chaotic-Good as a kind of touchy-feely, new-age types instead of the rugged individualists for a change.
