This thinker imagined Alexander the Great’s soul to illustrate both a “complete individual concept” and the “doctrine of marks and traces.” This thinker used Julius Caesar crossing the Rubicon (-5[1])to illustrate a theory of truth where predicates are contained within concepts. This thinker (-5[1])argued that only necessary truths are grounded on Aristotle’s principle of non-contradiction, while contingent truths are grounded in what this thinker called the Principle of Sufficient Reason. (10[2])Before his death in 1716, this thinker argued that the only beings were “windowless” simple substances, which are only fully understood by the all-knowing (10[1])God described in his Théodicée (10[1])(“tay-oh-dee-SAY”). For (10[1])10 points, name this optimistic German philosopher who wrote (10[1])Monadology (10[2])and claimed that (10[1])we lived in the best of all (10[1])possible (10[1])worlds. (10[1])■END■
