A Reaction

This spells out clearly the strongly pragmatist vein in Quine's thinking.


The 9 ideas from 'Carnap and Logical Truth'

If logical truths essentially depend on logical constants, we had better define the latter [Hacking on Quine]
In order to select the logic justified by experience, we would need to use a lot of logic [Boghossian on Quine]
Frege moved Kant's question about a priori synthetic to 'how is logical certainty possible?' [Quine]
Elementary logic requires truth-functions, quantifiers (and variables), identity, and also sets of variables [Quine]
Set theory was struggling with higher infinities, when new paradoxes made it baffling [Quine]
If set theory is not actually a branch of logic, then Frege's derivation of arithmetic would not be from logic [Quine]
Logical consequence is marked by being preserved under all nonlogical substitutions [Quine, by Sider]
Examination of convention in the a priori begins to blur the distinction with empirical knowledge [Quine]
Commitment to universals is as arbitrary or pragmatic as the adoption of a new system of bookkeeping [Quine]
