ABSTRACT
The division of labour in scientific investigations has resulted in the assignment of these different points of view to different sciences. Psychology and history have followed natural science in the assimilation of the idea of the norm. As the idea of the norm is thus transferred to the explicative sciences, so conversely is the standpoint of pure observation gradually extended to problems that were at first assigned to certain normative disciplines. Thus logic and ethics finally prove to be the only true normative sciences. In their significance as regulative sciences, logic and ethics embrace the whole realm of human knowledge. The early recognition of the normative character of ethics has exercised an unfavourable influence on the development of its methods. Although ethics, as a normative science, is not only related to logic but in a certain sense may be said to stand above it, the logical method of investigating and presenting facts is ill adapted to ethical inquiry.
