Cartesian way of thinking?
Cartesians adopted an ontological dualism of two finite substances, mind (spirit or soul) and matter. The essence of mind is self-conscious thinking; the essence of matter is extension in three dimensions. God is a third, infinite substance, whose essence is necessary existence.
