Discussion is sexual! It creates.
Zoologist Matt Ridley, in his TED presentation, uses the analogy of ideas having sex. Biologically, when genomes from a diverse set of people mix through sexual relations, our species evolves and remains strong and viable. Similarly, the ideas of two (or more) people may merge and then spawn a new idea, a progression from the original ideas, an evolution. And similar to how the health of our species depends on a good intermixing of sexual partners with unrelated genomes, so do the strength of our ideas and the vigour of our cultures depend on the courtship between parent ideas of great variety.
