  We note three ways to amend the RTT. First, we might put constraints on which hypotheses are acceptable. For example, Gupta and Belnap 1993 introduce a theory, Tc, of truth based on consistent hypotheses: an hypothesis h is consistent iff the set {A : h(A) = t} is a complete consistent set of sentences.  The relative merits of T*, T# and Tc are discussed in Gupta &amp; Belnap 1993, Chapter 6.
