  Kremer 2010 challenges this claim by precisifying it as a formal claim against which particular revision theories (e.g. T* or T#, see Definition 3.11, above) and particular three-valued theories can be tested. As it turns out, on many three-valued theories, truth does in fact behave like a classical concept when there's no vicious reference: for example, the least fixed point of a natural variant of the supervaluation scheme always assigns T a classical interpretation in the absence of vicious reference. Granted, truth behaves like a classical concept when there’s no vicious reference on Gupta and Belnap's theory T*, but, so Kremer argues, does not on Gupta and Belnap's theory T#. This discussion is further taken up by Wintein 2014.
