How is the question of God's existence posed today? Are the proofs provided by philosophy - such as those of Saint Thomas - conclusive? The answer depends on the role of reason. At stake is the existence of God as much as the existence of man, insofar as we adhere or not to the classical definition of man as a "living being endowed with reason" (zoon ekon logon). If you reject it, as the theoreticians of deconstruction do, you have to give up on a proof of God's existence based on a rational demonstration: it is then man who is dead, not God. If this is accepted, the question is whether the mere use of reason can demonstrate the existence of God. In this case, reason must humble itself and start from the existence of things perceived by the senses, since man is an incarnate spirit, a "living being endowed with reason". It is from this starting point that the question can and must be posed.
