5. Theory of Logic / A. Overview of Logic / 4. Pure Logic
14452 All the propositions of logic are completely general [Russell]

     From: Bertrand Russell (Introduction to Mathematical Philosophy [1919], XV)
5. Theory of Logic / A. Overview of Logic / 8. Logic of Mathematics
14462 In modern times, logic has become mathematical, and mathematics has become logical [Russell]
     Full Idea: Logic has become more mathematical, and mathematics has become more logical. The consequence is that it has now become wholly impossible to draw a line between the two; in fact, the two are one.
     From: Bertrand Russell (Introduction to Mathematical Philosophy [1919], XVIII)
     A reaction: This appears to be true even if you reject logicism about mathematics. Logicism is sometimes rejected because it always ends up with a sneaky ontological commitment, but maybe mathematics shares exactly the same commitment.
