Though the terms deduction, induction and abduction are not widely known or used, they point to three ways of thinking. Triadic Philosophy sees them as means of arriving at truth and beauty.

A Transuasive Argument, or Induction, is an Argument which sets out from a hypothesis, resulting from a previous Abduction, and from virtual predictions, drawn by Deduction, of the results of possible experiments …
