 Knowledge of essence is thus secured by a reliable connection with reality, which is due in part to the way we think about objects and form beliefs about them. Knowledge of essence, in turn, leads us to knowledge of necessity and possibility via a conceptual connection between essence and necessity. For Jago, “it is a conceptual truth that whatever is essentially \(F\) is necessarily \(F\)”; (2021: S1994) thereby, possessing the concepts of “essence” and “necessity”, together with the relevant essentialist knowledge jointly results in knowledge of necessity.
