 If by truth and falsity you mean something not definable in terms of doubt and belief in any way, then you are talking of entities of whose existence you can know nothing, and which Ockham’s razor would clean shave off. Your problems would be greatly simplified, if, instead of saying that you want to know the “Truth”, you were simply to say that you want to attain a state of belief unassailable by doubt. (1905 [1998: 336])
