However, if one wishes to summarize all determinations of value, without regard to the difference in classes and objects, there is no other name for the totality arising from this than that of aesthetics, to which practical philosophy also belongs in the scientific sense. Even the ancients, in distinguishing logic, physics, and ethics, had found the three parts of philosophy; and the separation must remain, because otherwise the various methods of investigation would mix and become confused.
2. In so far as one assumes the investigation is already completed, the separation whereby the aforementioned three sciences take on the form of three separate systems of instruction is no longer necessary. For any arbitrary purpose, it is common to bring the most diverse means and tools together in one place; the various doctrines of philosophy, as soon as each has been completed in its own place, can also allow for this. However, the condition is self-evident that, if one wishes to subject any of these doctrines to a new examination, it must first be returned to its proper scientific place and examined there in the appropriate context.
3. Not only can different philosophical doctrines be brought into a connection that deviates from their systematic position, but there are motives for why this should happen. Practical philosophy itself explicitly indicates these motives, as in several places in the course of its investigations a practical need for philosophy as a whole makes itself known, which would not be satisfied by a merely systematic knowledge of it.
