But now why is it that Teleology usually forms no proper part of theoretical natural science, but is regarded as a propaedeutic or transition to Theology?
It is in the teaching of reading that we find the formation of propaedeutic bonds of dubious value (with letters, phonograms, diacritical marks, and the like) often carried to demonstrably wasteful extremes.
The former sort of learning is, of course, appropriate with many of these propaedeutic bonds.
Consider, for example, exercises like those shown below which are propaedeutic to long division, giving the pupil some basis in experience for his selection of the quotient figures.
In some cases the bonds are purely propaedeutic or are formed only for later reconstruction.
The typical crutch forms a habit which has actually to be broken, whereas the purely propaedeutic bond forms a habit which is left to rust out from disuse.
Some such propaedeutic bonds may be worth while apart from their value in preparing for other bonds.
With him, this propaedeutic discipline, this tool of truth, perfectly performs its task of construction.
In the sense of a method whereby all scientific knowledge is secured, logic is a propaedeutic to the sciences.
It seems true that the founder of logic, Aristotle, regarded logic not as a science, but rather as propaedeutic to science, and not as an end in itself, but rather technically and heuristically as an instrument.
Of those who favor such a philosophical propaedeutic some recommend the History of Philosophy, others an Introduction to Philosophy of the type described in the preceding pages.
