Notes on <On the Fourfold Root of the Principle of Sufficient Reason> - Chapter 8
Chapter 8. General observations and results
§ 46. The Systematic Order.
The systematic order in which the different classes of reasons ought to follow one another is the following. First of all should come The Principle of Sufficient Reason of Being; and in this again first its application to Time, as being the simple schema containing only what is essential in all the other forms of the Principle of Sufficient Reason. The Reason of Being in Space having next been stated, the Law of Causality would then follow; after which would come the Law of Motives, and last of all the Principle of Sufficient Reason of Knowing; for the other classes of reasons refer to immediate [178]representations, whereas this last class refers to representations derived from other representations.
