Full Idea
Metaphysics is gradually and surely taking on the character of a logic. And finally seems destined to become more and more converted into mathematics.
Gist of Idea
Metaphysics is turning into logic, and logic is becoming mathematics

A Reaction
Remarkably prescient for 1898. I don't think Peirce knew of Frege (and certainly not when he wrote this). It shows that the revolution of Frege and Russell was in the air. It's there in Dedekind's writings. Peirce doesn't seem to be a logicist.
