  Anselm’s success in generating a whole host of divine attributes through the ontological argument does present him with a problem.  He must show that the attributes are consistent with each other – in other words, that it is possible for one and the same being to have all of them. For example, there seems at first glance to be a conflict between justice and omnipotence. If God is perfectly just, he cannot lie. But if God is omnipotent, how can there be something he cannot do? Anselm’s solution is to explain that omnipotence does not mean the ability to do everything; instead, it means the possession of unlimited power. Now the so-called “ability” or “power” to lie is not really a power at all; it is a kind of weakness. Being omnipotent, God has no weakness. So it turns out that omnipotence actually entails the inability to lie.
