Leibniz"s principles: psr, principle of contradiction (pc, a proposition "p" cannot be true and not true at the same time, principle of the best (pb, god can only choose the best, principle of the identity of indiscernibles (pii) For every true proposition, the notion of the predicate is contained in the notion of the subject. Represents leibniz"s understanding of truth and his understanding of the nature of individual substances. Identity: 2 ways to understand identity, numerical identity: the relation that a thing bears only to itself, qualitative identity: if two individuals share some property i. e. same eye colour, liking tomatoes. Numerical identity entails total qualitative identity - if 2 individuals share all the same properties, then they are numerically identical. Properties fall into 2 types: essential properties: properties that a thing must possess as long as it exists, accidental properties: properties that a thing can gain or lose over time i. e. wearing a jacket.
