The Secret Teachings of All Ages

Introduction

Philosophy is the science of estimating values. The superiority of any state or substance over another is determined by philosophy. By assigning a position of primary importance to what remains when all that is secondary has been removed, philosophy thus becomes the true index of priority or emphasis in the realm of speculative thought. The mission of philosophy a priori is to establish the relation of manifested things to their invisible ultimate cause or nature.

"Philosophy," writes Sir William Hamilton, "has been defined [as]: The science of things divine and human, and of the causes in which they are contained [Cicero]; The science of effects by their causes [Hobbes]; The science of sufficient reasons [Leibnitz]; The science of things possible, inasmuch as they are possible [Wolf]; The science of things evidently deduced from first principles [Descartes]; The science of truths, sensible and abstract [de Condillac]; The application of reason to its legitimate objects [Tennemann]; The science of the relations of all knowledge to the necessary ends of human reason [Kant];The science of the original form of the ego or mental self [Krug]; The science of sciences [Fichte]; The science of the absolute [von Schelling]; The science of the absolute indifference of the ideal and real [von Schelling]—or, The identity of identity and non-identity [Hegel]."
