There is a crisis in philosophical rationality today—in which modern logic is implicated—that can be traced to the abandonment of a common background of principles. The situation has no parallel within the pre-modern tradition, which not only admits of such principles, but also refers them back to a set of assumptions grounded in a clearly religious frame of mind. Modern conceptions of rationality claim complete independence from religious sources, as from tradition more generally, and typically end up disposing of first (...) principles altogether. The result is a fragmentation of reason, which can be seen to be dramatically exemplified in the realm of modern logic, populated by countless different systems and incompatible conceptions of what it is to be a logic. Many of the conceptual choices that became implicit in the philosophical discussions eventually leading to the rejection of the religious picture, and ultimately to the aforementioned crisis, were themselves originally linked to religious premises, so that all along, a kind of religious subconscious has subsisted throughout those disputations; however, the lack of any proper recognition of this background obstructs the possibility of making a reasonable assessment of the nature and causes of the crisis. Alasdair MacIntyre, whose thought inspires the argument developed here, reached similar conclusions regarding practical rationality and the effects of abandoning the teleological framework of Aristotelian philosophy. MacIntyre’s arguments can be adapted, as he suggests, to deal with reason more generally, and his insistence upon the tradition-laden character of rational enquiry can help point toward the grounding of human reason in religion.

Alethic pluralism, on one version of the view , is the idea that truth is to be identified with different properties in different domains of discourse. 1 Whilst we operate with a univocal concept of truth, and a uniform truth predicate, the thought is that the truth property changes from one domain to the next. So the truth property for talk about the nature and state of the material world may be different from the truth property for moral discourse .Tappolet (...) challenged alethic pluralism by asking how it can account for the truth of mixed compounds, such as a mixed conjunction like ‘this cat is wet and funny’, where each of the conjuncts are from different domains of discourse, and thus assessable in terms of different truth properties. She argues that the alethic pluralist is left in a dilemma: either admit of a ‘generic’ truth property, which can be possessed by propositions from all domains, thus rendering the plural ways of being true obsolete, or deny the truth of mixed conjunctions.In Edwards 2008, I argued that there is route out of Tappolet's dilemma. Briefly, I suggested that we acknowledge that the truth of a mixed conjunction is dependent on the truth of its conjuncts, and we should explain the truth of the conjunction by saying that it is true just in case each of its conjuncts is true. This, I argued, gives us an account of the truth of the conjunction without needing to appeal to a troublesome ‘generic’ truth property.Aaron Cotnoir criticizes my solution to Tappolet's problem. Cotnoir argues that my solution to the problem admits of an unacceptable ‘proliferation’ of truth properties, and smuggles in a generic truth property. I …. (shrink)
