The Evolution of Welfare Economics

Imagine yourself as an assistant professor and getting this letter from America's most well-known economist.

I should not be surprised if someone who imposes more conditions on a Bergson function than he did, or than I would care to do in most applications, should be able to come up with an impossibility theorem [...]. At my hasty first reading I did not find anything appealing in your neutrality axiom. Arrow, for his voting problem, after all nominates axioms that people have thought appealing until he showed them what their implications were in the context of assuming other appealing axioms.
Samuelson to Parks, 1973
