When is a reason not a reason?
There are two ways we use the word ‘reason’ of interest to us here (I will be ignoring ‘reason’ used to mean ‘rational’). The first (A-type) is used to explain something with respect to factual events or the past; i.e. the reason the sky is blue is because molecules in the air scatter blue light more than they do red, or the reason I broke my leg was because I fell off my bike. The second type of reason (B-type) also explains something but is future-oriented; i.e. the reason she bought a bigger car is because she wants a large family. Importantly, while only conscious agents can have B-type reasons, anything can have an A-type reason.
The central problem I want to address in this article is whether all B-type reasons ultimately cash out as A-type reasons.
