 A set of acts, \(α_j\), is, as of \(t_i\), scrupulously securable by S if and only if there is a time, \(t_j\), that either immediately follows \(t_i\) or is identical to \(t_i\), a set of acts, \(α_i\), (where \(α_i\) may, or may not, be identical to \(α_j\)), and a set of background attitudes, B, such that the following are all true: (1) S would perform \(α_j\) if S were to have at \(t_i\) both B and the intention to perform \(α_i\); (2) S has at \(t_i\) the capacity to continue, or to come, to have at \(t_j\) both B and the intention to perform \(α_i\); and (3) S would continue, or come, to have at \(t_j\) B (and, where \(α_i\) is not identical to \(α_j\), the intention to perform \(α_i\) as well) if S both were at \(t_i\) aware of all the relevant reason-constituting facts and were at \(t_j\) to respond to these facts/reasons in all and only the ways that they prescribe, thereby coming to have at \(t_j\) all those attitudes that, given those facts, she has decisive reason to have and only those attitudes that she has, given those facts, sufficient reason to have.
