This is an attempt to examine a belief prevalent in many works on the philosophy of the sophist that as a school of thought the sophists were relativists, or to be more precise, ethical relativists. The article is composed of two main parts. The first part offers a theoretical framework for the following analysis which starts from presenting and discussing a theory of ethical mutabilism formulated by the Polish philosopher Wladyslaw Tatarkiewicz. The second part contains a review of sophistic opinions on ethical values and attempts to show that they cannot be considered relativistic without further qualifications.
