ABSTRACT
The Principle of Sufficient Reason has long been held as a fundamental axiom and can be stated as that every event that happens or being which exists must have some cause or reason sufficient to bring it about and thus explain its happening or existence. The Principle of Ultimate Intelligibility can be stated as no event or being merely happens or exists as a "brute fact", but always there is something which would fully explain it until we reach that which is self-explanatory. We need to distinguish between "absolute" and "relative" properties or between "absolute" and "relative" attributions of the same property. Some properties, and the terms for them, do not permit of a "more or less" but are or denote a "perfection" or norm to which there can be lesser and greater degrees of approximation and from which there can be lesser and greater degrees of divergence but of which there are no degrees.
