It should be noted here that the idea of two parts does not always mean only two parts. Two parts happens to be the minimum of parts, obviously, and two parts will always have a relationship if they are parts of a whole. Thus the simplest machine always has three parts. It is the relationships that are common to all parts. Relationships are common to everything, so a language of relationships must speak to everything.
Relationships are usually verbs, gerunds, based on action rather than identity.
Relationships are the core of mathematics, the foundation of science, and essentially the whole of art, music and love. Interestingly, this principle is not new. Indeed, it can be found as far back as 600 B.C. when Lao Tzu spoke of it in Chap. 42 of the Tao Te Ching. In modern terms, Information theory is similar but, again, one of those particular theories.
