The Logic of Reasons
Shyam Nair, John F. Horty · Oxford University Press eBooks · 2018
We discuss the need for and prospects of a logic describing the relation among reasons and the outcomes they support. After noting some shortcomings of the dominant weighing conception of this support relation, we very briefly outline the basic idea behind two attempts at providing such a logic. We then describe a few topics that are ripe for further research: the logical relations among reasons themselves, the source and formal structure of priority relations among reasons, whether the strengths of multiple reasons can combine, and a problem concerning the strength of undercutting defeaters.
