I argue that Moore's propositions, for example, 'I went to the pictures last Tuesday but I don't believe that I did' cannot be rationally believed. Their assertors either cannot be rationally believed or cannot be believed to be rational. This analysis is extended to Moorean propositions such as God knows that I am an atheist and I believe that this proposition is false. I then defend the following definition of assertion: anyone asserts that p iff that person expresses a belief that p with the intention of causing relevant epistemic change in the cognition of an actual or potential audience

John Turri gives an example that he thinks refutes what he takes to be “G. E. Moore's view” that omissive assertions such as “It is raining but I do not believe that it is raining” are “inherently ‘absurd'”. This is that of Ellie, an eliminativist who makes such assertions. Turri thinks that these are perfectly reasonable and not even absurd. Nor does she seem irrational if the sincerity of her assertion requires her to believe its content. A commissive counterpart of Ellie is Di, a dialetheist who asserts or believes that The Russell set includes itself but I believe that it is not the case that the Russell set includes itself. Since any adequate explanation of Moore's paradox must handle commissive assertions and beliefs as well as omissive ones, it must deal with Di as well as engage Ellie. I give such an explanation. I argue that neither Ellie's assertion nor her belief is irrational yet both are absurd. Likewise neither Di's assertion nor her belief is irrational yet in contrast neither is absurd. I conclude that not all Moore-paradoxical assertions or beliefs are irrational and that the syntax of Moore's examples is not sufficient for the absurdity found in them

Starting with my (1988) and largely continued by David Ruben’s instructive (2013a), a lively debate has occurred over how one is to analyze the concepts of true succession and membership of a tradition in order to identify the source of the intractability typically found in disputes in which two groups each claim that it, but not its rival, is in the tradition of some earlier group. This debate was initially between myself (2013a, 2013b) and Ruben (2013b, 2013c) but later involved Samuel Lebens (2013a, 2013b), Jonathan Payton (2013a, 2013b), Martin Beckstein (2014a, 2014b) and Ruben (2013d, 2014a, 2014b). The time seems ripe to summarize the main lines of the debate to try to draw some lessons from it as we go along and then indicate possible further lines of inquiry.
