 Gregory chooses as the object of scientific knowledge the alternative offered by Adam Wodeham. Chatton’s notion of “thing” in scientific knowledge was the state of affairs signified by both the negative and the affirmative proposition. For example, “Socrates is sitting” and “Socrates is not sitting” signify for Chatton the same thing, not Socrates, not sitting, and not the propositions, but somehow the whole Socrates’s-being-seated. Although Chatton had his reasons for his theory, Wodeham modified it in a useful way, differentiating between positive and negative states of affairs. Thus for Wodeham, each proposition has its own total significate that is only complexly signifiable (complexe significabile), so that Socrates’s-being-seated and Socrates’s-not-being-seated are two different things, the objects of scientific knowledge.
