Life Anselm was born in in Aosta, a border town of the kingdom of Burgundy. In his adolescence, he decided that there was no better life than the monastic one.
These are mostly toy examples. But they serve to highlight the deficiencies which more complex examples also share.
God is a being which has every perfection. This is true as a matter of definition. Existence is a perfection. I conceive of a being than which no greater can be conceived.
If a being than which no greater can be conceived does not exist, then I can conceive of a being greater than a being than which no greater can be conceived—namely, a being than which no greater can be conceived that exists. I cannot conceive of a being greater than a being than which no greater can be conceived.
Hence, a being than which no greater can be conceived exists. It is possible that that God exists. God is not a contingent being, i.
Hence, it is necessary that God exists. See MalcolmHartshorneand Plantinga for closely related arguments. Hence, the existent perfect being is existent. Hence, God is existent, i. The last step is justified by the observation that, as a matter of definition, if there is exactly one existent perfect being, then that being is God.
See Rescher for a live version of this argument. Whenever a bunch of things exist, their mereological sum also exists.
Therefore the sum of all things exists. Therefore God—the sum of all things—exists. Say that a God-property is a property that is possessed by God in all and only those worlds in which God exists. Not all properties are God properties. Any property entailed by a collection of God-properties is itself a God-property.
The God-properties include necessary existence, necessary omnipotence, necessary omniscience, and necessary perfect goodness.
Hence, there is a necessarily existent, necessarily omnipotent, necessarily omniscient, and necessarily perfectly good being namely, God.
Of course, this taxonomy is not exclusive: Moreover, an argument can be ambiguous between a range of readings, each of which belongs to different categories.
This latter fact may help to explain part of the curious fascination of ontological arguments. Finally, the taxonomy can be further specialised: Characterisation of Ontological Arguments It is not easy to give a good characterisation of ontological arguments.
Consider, for example, the claim that I conceive of a being than which no greater can be conceived. However, it is unclear how that traditional characterisation should be improved upon. This procedure would make good sense if one thought that there is a natural kind—ontological arguments—which our practice carves out, but for which is hard to specify defining conditions.
Moreover, this procedure can be adapted as a pro tem stop gap:Video: St. Anselm's Ontological Argument for God's Existence This lesson will explore the ontological argument for God. In doing so, it will highlight the .

Anselm replies and at a glance it appears as though Anselm ignores Gaunilo’s argument however, upon close inspection Anselm does respond to the criticisms of Gaunilo. Anselm’s main argument in the Proslogion is thought to be the Proslogion II titled That God Truly Exists.

The ontological argument of Anselm of Canterbury has long since captivated the minds of many philosophers and apologists. Not long after Anselm published his Proslogion, his devotional apologetic was criticized by Gaunilo, yet Anselm’s argument was taken up by many of the West’s most prominent thinkers, such as Descartes and Leibniz, both .
