 A number of arguments have been given for this principle, many of them parallel to the previously mentioned arguments for the axioms of probability. Some appeal to Dutch books (Teller 1973; Lewis 1999), others to the pursuit of cognitive values (Greaves and Wallace 2006), especially closeness to the truth (Leitgeb and Pettigrew 2010a,b), and still others to the idea that one should generally revise one’s beliefs as little as possible when accommodating new information (Williams 1980).
