Inflation, Communication, and Noise

In 1948, Claude Shannon published “A Mathematical Theory of Communication” in the Bell System Technical Journal, a paper that established information theory as a formal discipline. Shannon’s central contribution was to show that information can be measured, that communication channels have finite capacity, and that—when noise is introduced into a channel—the receiver’s ability to reconstruct the original message degrades in precise, calculable ways.

McMahan On Killing in War

Jeff McMahan wrote a genuinely revolutionary book, Killing in War (OUP, 2009), which uncovered a flaw in standard just-war theory. The standard view sharply separates the morality of going to war—jus ad bellum—from the morality of warfare—jus in bello. Whether or not a war is just does not affect the morality of how war is to be conducted.
