The Strong Version of Underdetermination of Theories by Empirical Data
Comments on Wolenski's Analysis

The Polish researcher in the field of logic and philosophy, Jan Woleński, in one of his recent articles, „Metalogical Observations About the Underdetermination of Theories by Empirical Data," logically formalized two weak and strong versions of the underdetermination of theories by empirical data (or UT by abbreviation) and with these formalization has metalogically analyzed these two versions. Finally he has deducted that the weak version is defensible while the strong version is not. In this paper we will critically study Woleński's analysis of the strong version of UT.
