Comment on ‘Ditch ‘ceteris paribus’!’

You say: “Rigorous deductions from precise axioms is mathematics, not economics, not science.”

“It is my conviction that pure mathematical construction enables us to discover the concepts and the laws connecting them which give us the key to the understanding of the phenomena of Nature. Experience can of course guide us in our choice of serviceable mathematical concepts; it cannot possibly be the source from which they are derived; experience of course remains the sole criterion of the serviceability of a mathematical construction for physics, but the truly creative principle resides in mathematics.” (Einstein, 1934, p. 167)

It is pretty obvious that you do not understand the relationship between science and mathematics and in particular of economics, science, and mathematics.*

The answer to your question ‘Do we have to keep saying it over and over?’ is therefore No.
