Abstract

This paper is based on the assumption that critical rationalism represents a middle position between absolutist and relativistic positions because it rejects all attempts of ultimate justification as well as basic relativistic claims. Even though the critical-rationalist problem-solving-approach based on the method of trial and error leads to an acknowledgment of the plurality of theories and moral standards, it must not be confused with relativism. The relativistic claims of the incommensurability of cultures and the equality of all views of the world and all moral systems can be challenged by two basic critical‐rationalist arguments:(1) Popper’s critique of ‚the myth of the framework’; (2) the criticalrationalist conception of different levels of rationality (Albert, Agassi and Jarvie). In ethics moral standards and norms can be interpreted from a critical‐rationalist perspective as undogmatic suggestions for the regulation of social behaviour and as attempts to answer different problems, resulting from social life. This allows for the comparison of different moral standards, norms, practices and institutions with reference to the underlying problem situation and the search for culturally overlapping moral standards.
