By interpretation, I assume you mean a Tarski-style model theory
in which the axioms are evaluated in terms of the real world.

I assume that your sample axiom that begins "harzburgite(x) = "
has an implicit universal quantifier. The use of numeric
functions and relations is common in first-order logic. (05)
