 For any two terms \(A\) and \(B\), \(A\) is a determinate of \(B\) if and only if \(A\) is a non-conjunctive specifier of \(B\), and \(A\) is logically related to all other non-conjunctive specifiers of \(B\) [where] any two terms are logically [i.e., conceptually] related if either entails the other or either entails the negation of the other. (1959: 148)
