Why It Is Difficult To Defend the Plantinga-Type Ontological Argument

The Plantinga-type ontological argument may be tersely represented as follows: (1) If a maximally great being (MGB) is possible, then a MGB exists; (2) a MGB is possible; (3) therefore, a MGB exists. The key premise in this type of ontological argument is the possibility-premise, namely, that it is...

Description
Summary:The Plantinga-type ontological argument may be tersely represented as follows: (1) If a maximally great being (MGB) is possible, then a MGB exists; (2) a MGB is possible; (3) therefore, a MGB exists. The key premise in this type of ontological argument is the possibility-premise, namely, that it is possible that a MGB exists. But why affirm the possibility-premise? Proponents of the argument could claim that they have a strong modal intuition that the possibility-premise is true. Unfortunately, critics could likewise claim that they have a strong modal intuition that it is possible that a MGB does not exist or that it is possible that a semi-maximally great being exists, with these premises implying that a MGB does not exist. In this paper, I argue that, in light of this objection to the possibility-premise, the Plantinga-type ontological argument is difficult to defend. I then, however, offer a suggestion as to how one may argue for the existence of a MGB without defending the possibility-premise.
