 Besides definite answers ‘If \(p\), \(q\) will result’, we often get ones ‘If \(p\), \(q\) might result’ or ‘\(q\) would probably result’. Here the degree of probability is not a degree of belief in ‘Not-\(p\) or \(q\)’, but a degree of belief in \(q\) given \(p\), which it is evidently possible to have without a definite degree of belief in \(p\), \(p\) not being an intellectual problem. And our conduct is largely determined by these degrees of hypothetical belief. (1929b, [FM] 246)
