 Cudworth’s True Intellectual System propounds an anti-determinist system of philosophy grounded in his conception of God as a fully perfect being, infinitely wise and good. The created world reflects the perfection, wisdom and goodness of its creator. It must, therefore be orderly, intelligible, and organised for the best. This anti-voluntarist understanding of God’s attributes is also the foundation of epistemology and ethics, since God’s wisdom and goodness are the guarantors of truth and of moral principles. By contrast, a philosophy founded on a voluntaristic conception of the deity would have no ground of certainty or of morality because it would depend on the arbitrary will of God who could, by arbitrary fiat, decree non-sense to be true and wrong to be right. It follows that misconceptions of God’s attributes, which emphasise his power and will, result by definition in false philosopical systems with sceptical and atheistic implications.
