 That is, a proposition \(p\) is ethically neutral if the truth or falsity of \(p\) is a matter of indifference to the subject, regardless of the wider context in which its truth or falsity obtains. Having characterised ethical neutrality in terms of preferences, Ramsey is ultimately able to construct a definition (in terms of preferences over gambles) for when the difference in utility between two worlds \(\omega_1\) and \(\omega_2\) is equal to that between \(\omega_3\) and  \(\omega_4\).[4]
