 For Heytesbury, paradoxes are obligational games with self-referential  sentences.[40]  However, his criticism of alternative solutions is part of the fourteenth-century developments relating paradoxes to general logico-semantical  issues.[41]  He views his approach as relatively defensible and probable, but admits that he cannot solve all objections and considers a completely satisfactory solution to paradoxes impossible (unfortunately without a justification). Without too much self-confidence, he closes his treatise by saying that young students should move past the topic and do something useful. ([RSS] 1494: fol. 4vb and 7rb [1979: 21 and 58])
