ABSTRACT
The Greek classical conception included values and norms as proper objects of study and knowledge. The principal argument against the possibility of a normative science proceeds from the assumption that science can deal only with facts of existence, to the conclusion that judgments of what ought to be are so arbitrary that no science of norms is possible. This view of the nature of science is an exceedingly superficial one. Reflective thought, however, has not hesitated to challenge the absolutism of moral rules, since the Greek philosophers introduced the habit of free inquiry into human affairs. It has been observed that people's views as to what is right and wrong differ in different countries. Logic is concerned with a common world. Its processes may help us to locate such a world within the apparent chaos and discord of conflicting human ideals.
