Full Idea
It might be contended that, in describing what happens when a man believes 'p or q', the 'or' that we must use is not the same as the 'or' of logic.
Gist of Idea
Maybe the 'or' used to describe mental states is not the 'or' of logic

A Reaction
This seems to be the general verdict on Russell's enquiries in this chapter, but I love any attempt, however lacking in rigour etc., to connect formal logic to how we think, and thence to the world.
