Having elucidated the main features of the nature of the practical sphere, we are now prepared to examine the specific nature of the ethical deed. The first question that arises is whether it is possible to consider the nature of the ethical deed without first considering the nature of the ethical norm — that is, the nature of the good to which the deed as an ethical deed is related. This problem is beset with grave difficulties; indeed, there is room for doubt as to the phenomeno-logical isolation that separates the deed in its dynamic character from the good as representing the aspect of content. This difficult question can be answered only at the end of our inquiry, though even then some doubts will remain concerning this methodological and material isolation.
