In this article, I argue, contrary to a noticeable trend in Whitehead scholarship, that in Whitehead's system propositions and their truth-values are objective in the sense that their own identities are independent of any particular subjects feeling or knowing them. This stance reinforces a core value of Whitehead's philosophy: his realism. As part of this argument, I examine Whitehead's analysis of an actual entity's determination and provide a more precise definition of what it means for a proposition to be true (...) or false.
