The problem of underdetermination

Abstract

We are examining the problem of underdetermination of theory by data starting from the thesis of empirical equivalence as the strongest form in which underdetermination is formulated. We will consider the consequences of this thesis on the basis of different attempts to resolve it, whereby untenability of realistic and some antirealist solutions of a problem is envisaged. The acceptance of pragmatic (non-realist) stance marks a departure from the final solution on behalf of a practical decision making in circumstances of de facto underdetermination.
