论笛卡尔《哲学原理》中关于上帝存在的证明
On the Proof of the Existence of God in Descartes’ Principia Philosophiae

笛卡尔在《哲学原理》中用了三条路径来证明上帝的存在，前两条都是以“我思故我在”为基础进行的证明，第三条是从上帝观念的完满性必然包含存在性进行的证明。不过，第三条路径的本体论证明理由并不充分，从上帝观念的完满性可以推出存在性，但同时也能推出不存在性。
Descartes used three roads in his Principia Philosophiae to prove the existence of God. The first two are based on “ego cogito ergo sum”, and the third is a proof that the completeness of the concept of God inevitably includes existence. However, the ontological justification of the third road is not sufficient. Existence can be inferred from the completeness of the concept of God, but non-existence can also be inferred.
