Abstract
One can assign three different aims to the desire for knowledge : utility, pleasure, truth-for-truth's-sake. Whereas the first two aims have a concretely determinable content and therefore look evident, the third one has been looked upon as strange and problematic : it is not immediately clear what kind of value is defended in this case. Popper is one of the recent defenders of the traditional ideal of truth-for-truth's-sake. He wants to defend the ideal against three positions : a primitive taboo-ridden fear for knowledge and truth, relativism, instrumentalism. Analysing Popper's ethic of cognition we do not agree with the instrumentalist's critique of it. However, precisely in advocating a non-instrumentalist value, Popper's position is not unique, but paradoxically resembles the „primitive” position. Popper's belief that there is an objective or absolute truth is, in his opinion, implied by the belief that the search for knowledge makes sense. We try to show that this thesis of absolute truth is based on a conceptual mistake. In opposition to Popper's view, we sketch a form of relativism avoiding this confusion, without doing away with any concrete possibility of discussion or search for truth. At the same time, we try to understand Popper's aversion to relativism as well as the appeal of his position, in that it is a strange mixture of a heroic cognitive ethic and a desire for imaginary control over the uncontrolable. We argue that the form of relativism we advocate easily and perhaps better fulfilb the „heroic” readiness to forsake security in cognitive matters
