The general theory of objective knowledge flows through the preceding writings on systemics and related subjects.
The general categorical method for objective knowledge is called categorical deduction (described in more detail in my book titled The Dimensional Philosopher's Toolkit).
Essentially, it consists of four categories: A, B, C, and D, which are each polar opposites which cross along the diagonal.
The formula to reach a deduction takes a binary format, in spite of the four categories used, rendering the system exponentially efficient.
1. [A-B : C-D], 2. [A-D : C-B].
(the hyphens designate combinations, often by taking the quality of one term and the noun of another term. For example, 'Buddhism' and 'Monk' would equal 'Buddhist Monk'.
In this precise format, and using polar opposites opposed diagonally, it yields statements of truth coherently, a kind of ultimate in the pursuit of knowledge.
