comment Was the early calculus inconsistent?
I have mixed feelings about this entire thread. On the one hand, I am now aware of various papers written by katz et al. I have previously read a lot of Dunham, Grabiner, etc, and it is good to see a counterpoint to their position. However, I feel that the question was posed by katz merely as an excuse to give the above answer (with a personal citation). katz's previously closed post supports this. I find this frustrating, and it dampens my interest in katz's papers. If this is the case, I hope katz will take a different approach in the future. If not, I'll be glad to hear otherwise.

... Thus, the early practitioners found their techniques consistent, and modern commentators find their use of zero/non-zero quantities in proofs inconsistent.

comment Was the early calculus inconsistent?
The question is not clear, as the word "consistent" has multiple meanings. One must separately consider consistency of techniques and consistency of the arguments used to justify techniques. The practitioners of the early calculus viewed it as a set of legitimate methods for obtaining results that agreed with other methods and physical observation. They also treated certain quantities as both zero and non-zero in proofs, which is inconsistent with modern proof practice...
