And, besides the propaedeutic importance which thus belongs to it, another fact has to be taken into account in estimating the influence of Neoplatonism.
We must look for ethics to supply the corner-stone of metaphysics, and psychology is a necessary propaedeutic. The System der Philosophie (1899; 3rd ed., 1907) contained the results of Wundt's work up to that date, both in the domain of science and in the more strictly philosophic field.
Fichte's " Wissenschaftslehre," he said, is a completely untenable system, and a metaphysics of fruitless apices, in which he disclaimed any participation; his own Kritik he refused to regard as a propaedeutic to be construed by the Fichtian or any other standpoint, declaring that it is to be understood according to the letter; and he went so far as to assert that his own critical philosophy is so satisfactory to the reason, theoretical and practical, as to be incapable of improvement, and for all future ages indispensable for the highest ends of humanity.
Laurie's metaphysics is an attempt to supply a psychological propaedeutic to Hegelian metaphysics.
The man of the world who had cultivated it in his youth regarded it in riper years as a foolish pedantry, or at best as a propaedeutic exercise; while the serious student, necessarily preferring that form of disputation which recognized truth as the end of this, as of other intellectual processes, betook himself to one or other of the philosophies of the revival.
It is to be regarded as a propaedeutic, 12 which, although it is in contact with reality in and through the metaphysical import of the axioms, or again in the fact that the categories, though primarily taken as forms of predication, must also be regarded as kinds of being, is not directly concerned with object-reality, but with the determination for the thinking subject of what constitutes the knowledge correlative to being.
The science of the form of thought abstracted in this way from its matter or content was regarded as of value both as propaedeutic and as canon.
