Arno Ros

Ros studied Ibero-Romance languages, sociology, literature and philosophy in Hamburg, Madrid (Spain) and Coimbra (Portugal).

In his lectures he takes particular care to examine complicated problems by clearly distinguishing between their logical-methodological and historical components.

The term 'concept' is understood by Ros along lines suggested by Ludwig Wittgenstein's later work, that is, as a linguistic classificatory ability or habit.

The epistemological starting point is that we as subjects can only acquire knowledge about parts of the world by classifying objects (entities), that is, by making use of our classificatory abilities.

The problem lies in the fact that our classificatory abilities may be learned, dependent on culture, or biologically conditioned, whereby the possibility of objective justification can be called into question.
