Triad

Have you ever wondered why humans pay so much attention to the number three?
Why are triads like beginning–development–completion, past–present–future, birth–life–death, perception–reflection–action, observation–learning–application, tonic–third–fifth, or a DNA codon so harmoniously balanced?
Three often create stable systems, either by balancing them or by establishing confident dominance.
One point is a fact.
Two points create tension.
Three points form a system capable of holding its shape.

I think a triad can confidently be called the minimal framework of meaning.
