Kenneth Arrow's pathbreaking ?impossibility theorem" was a watershed in the history of welfare economics, voting theory, and collective choice, demonstrating that there is no voting rule that satisfies the four desirable axioms of decisiveness, consensus, nondictatorship, and independence. In this book, Amartya Sen and Eric Maskin explore the implications of Arrow's theorem. Sen considers its ongoing utility, exploring the theorem's value and limitations in relation to recent research on social reasoning, while Maskin discusses how to design a voting rule that gets us closer to the ideal?given

These are the sheets of a presentation on June 8 2018, at the conference of Dutch and Flemish political science. These sheets give an overview, and see "Voting Theory for Democracy" (VTFD) for precision. Arrow's theorem is that four axioms would be reasonable and morally required each by themselves, but together they result into a contradiction. The deduction stands but the interpretation can be rejected. Arrow confuses voting and deciding. The axiom of "pairwise decision making" can be rejected - and Arrow's label "independence of irrelevant alternatives" is distractive. A method that many would find interesting is Borda Fixed Point. ; This is an update of the sheets of my presentation on March 16 2001 for the Social Choice group in Tilburg, The Politicologenetmaal 2018 has this link: https://politicologenetmaal.eu See Voting Theory for Democracy at https://zenodo.org/record/291985

This book develops John Dewey's broad conception of social conflict as a natural process of discovery and preference adjustment, resolving Kenneth Arrow's famous theorem of the impossibility of ordering diverse preferences through voting. It addresses the nature and resolution of today's urgent problems and political polarization.
