analytic-synthetic

"An axiomatic concept is the identification of a primary fact of
reality, which cannot be analyzed, i.e., reduced to other facts or
broken into component parts."

And yet Peikoff railed against the so-called analytic-synthetic dichotomy.

What's ironic is the Objectivist definition of "axiom" - in which you will find
the very idea of analysis itself, and even the word "analyzed." It is
just a short step for them to understand that putting the "broken"
component parts back together again involves nothing more than a
synthesis of those parts.
