 Ani believes that salmon are fish; not knowing that whales are mammals, she also believes that whales are fish. Sanjay, like Ani, believes that salmon are fish, but he denies that whales are fish. Do Ani and Sanjay share exactly the same belief about salmon—namely, that they are fish—or is the content of their belief somehow subtly different in virtue of their different attitude toward whales? With certain caveats, the atomist will say the former, the holist the latter. In general, the atomist holds that the content of one’s beliefs does not depend in any general way on one’s related beliefs (though it may depend on the contents of a few specially related beliefs such as definitions) and thus, consequently, that people who sincerely and comprehendingly accept the same sentence normally have exactly the same belief. Holism is the contrary view that the content of every belief depends to a large degree on a broad range of one’s related beliefs, and consequently that two people will rarely believe exactly the same thing.
