School Embodiments
Paradigm early modern rationalism — systematic metaphysics from divine perfection and sufficient reason.
"Every individual substance contains within its complete concept everything that can ever be predicated of it." (Discourse §8)
Complete-concept theory anticipates monadological idealism.
"Each substance is a mirror of the entire universe." (Discourse §9)
Major Leibnizian theodicy — best of all possible worlds.
"God always chooses the best; this is the best of all possible worlds." (Discourse §3)
Realist about substances and divine framework.
"Substances are real and their complete concepts express their entire reality." (Discourse §8)
Major source for modern analytic philosophy of substance, modality, identity.
"What is necessary cannot be otherwise; what is contingent is what could have been otherwise but is by divine choice." (Discourse §13)
Engages Aristotelian-Thomistic substantial-forms tradition.
"What the scholastics called substantial forms I have restored under modified form." (Discourse §10)
Complete-concept theory implies eternalism about individual lives.
"Caesar's crossing of the Rubicon was eternally settled in his complete concept." (Discourse §13)
