- He argues that he cannot be the cause of his own existence, nor can his existence be adequately explained by his parents or any causes less perfect than God, because if he were causa sui he would lack no perfections of which he has an idea, and producing a thinking being from nothing is a greater effect than acquiring accidental perfections.
- His overarching aim is to learn to distinguish the true from the false to guide life with confidence; exposure to diverse customs reveals the relativity of practices and tempers premature judgment.
- The method maximally exercises reason and habituates the mind to clearer and more distinct conceptions, and because it is not tied to any particular subject, it can be applied across the sciences.
- The idea of God as an infinite, eternal, immutable, independent, all-knowing, all-powerful creator contains such great and excellent perfections, with maximal objective reality, that it cannot originate from his finite self; therefore God, an actually infinite substance, must exist as its cause.
- Neither the will itself nor the understanding, taken in themselves, are the source of error, since both are perfect in their kind; error arises only when the will, which ranges more widely than the understanding, assents to or chooses with respect to matters that are not clearly and distinctly understood.
- From the idea of a more perfect being present in the mind, Descartes infers the existence of God as the more perfect cause of that idea.
- The rational (reasonable) soul cannot be produced by matter’s powers; it must be expressly created by God and is more intimately united to the body than a pilot to a ship in order to have sensations and appetites and constitute a real human.
- One should reject any belief accepted merely by example and custom, because such beliefs produce errors that obscure natural intelligence and hinder the capacity to listen to reason.
- He chose to record rigorously tested results but not publish them in his lifetime, to avoid controversies, oppositions, and reputation that would steal time from his ‘grand design,’ while still benefiting the public and posterity.
- Traditional logic, ancient analysis, and modern algebra are inadequate as investigative methods; therefore Descartes seeks a new method that retains their advantages without their defects.
