A theory of knowledge might presuppose a synthetic frame of reference (sfr), as a context.

Assuming this we proceed ab initio in such fashion as required, to elucidate what might be considered "knowledge", as opposed to merely persistent state.

The formation of perception or synthesis of apprehension might in turn depend on the fundamental a priori mechanics, of an embedded set of operators referred to as the categories (see "The Critique of Pure Reason", Immanuel Kant, 1781, SS6).
