 Some people object to the distinction between belief and acceptance. Horwich (1991), O’Leary-Hawthorne (1997), and Burgess and Rosen (1997) present arguments for the claim that there is no real difference between acceptance and belief because, roughly, (a) to believe something is just to be disposed to behave in certain ways, and (b) those who believe that 2 + 2 = 4 and those who allegedly only accept that 2 + 2 = 4 are presumably disposed to behave in exactly the same ways.
