ABSTRACT
There is a doctrine which deals with the meaning of the word "moral" or "good", and with the manner in which these meanings are consciously apprehended; and this doctrine is wholly different from that which deals with the particular content of the good. In the narrower sense of the term Ethics is a theoretical science, and as such is a doctrine of human actions; and of course it is in this sense alone that it can be the basis of rules. For Ethics remain "Ethics"—that is a structure of particular concepts and propositions, valid in the field of the "it ought to be" and indifferent to the existence or non-existence of freedom. Ethical principles may be divided into two classes: into prohibitions and commandments or into propositions having the form "it ought not to be" or "it ought to be".
