Quote of the day : the ethical “success” of probability

I am reading Ian Hacking’s The Taming of Chance, which I picked up from The Seminary Coop upon arriving here. They just had it on the shelf! The book, as he puts it, is a way to understand why probability has been “an incredible success story” in the realms of metaphysics, epistemology, logic, and ethics. By success he means probabilistic ideas have radically changed these areas. On the last point:

Ethics is in part the study of what to do. Probability cannot dictate values, but it now lies at the basis of all reasonable choice made by officials. No public decision, no risk analysis, no environmental impact, no military strategy can be conducted without decision theory couched in terms of probabilities. By covering opinion with a veneer of objectivity, we replace judgement by computation.
