Ancient Greek philosophy was divided into three sciences: physics, ethics, and logic. This division is perfectly suitable to the nature of the thing; and the only improvement that can be made in it is to add the principle on which it is based, so that we may both satisfy ourselves of its completeness, and also be able to determine correctly the necessary subdivisions. All rational knowledge is either material or formal: the former considers some object, the latter is concerned only with the form of the understanding and of the reason itself, and with the universal laws of thought in general without distinction of its objects. Formal philosophy is called logic. Material philosophy, however, has to do with determinate objects and the laws to which they are subject, is again twofold; for these laws are either laws of nature or of freedom. The science of the former is physics, that of the latter, ethics; they are also called natural philosophy and moral philosophy respectively.

The critique of practical reason. E-book. Formato Mobipocket Immanuel Kant   -  Pubme, 2015  - 

This work is called the Critique of Practical Reason, not of the pure practical reason, although its parallelism with the speculative critique would seem to require the latter term. The reason of this appears sufficiently from the treatise itself. Its business is to show that there is pure practical reason, and for this purpose it criticizes the entire practical faculty of reason. If it succeeds in this, it has no need to criticize the pure faculty itself in order to see whether reason in making such a claim does not presumptuously overstep itself (as is the case with the speculative reason). For if, as pure reason, it is actually practical, it proves its own reality and that of its concepts by fact, and all disputation against the possibility of its being real is futile.

The metaphysical elements of ethics. E-book. Formato Mobipocket Immanuel Kant   -  Pubme, 2015  - 

Ethics in ancient times signified moral philosophy (philosophia moralis) generally, which was also called the doctrine of duties. Subsequently it was found advisable to confine this name to a part of moral philosophy, namely, to the doctrine of duties which are not subject to external laws (for which in German the name Tugendlehre was found suitable). Thus the system of general deontology is divided into that of jurisprudence (jurisprudentia), which is capable of external laws, and of ethics, which is not thus capable, and we may let this division stand.
