Peirce, An Odd Remark

Tue Nov 15, 2005

Professor Royce remarks that my opinion that differentials may quite logically be considered as true infinitesimals, if we like, is shared by no “mathematicians outside of Italy.” As a logician, I am more comforted by corroboration in the clear mental atmosphere of Italy than I could be by any seconding from a tobacco-clouded and bemused land (if any such there be) where no philosophical eccentricity misses its champion, but where sane logic has not found favor.
