Question
Hello Dr. Craig, my question is in regards to the Ontological Argument. If the proposition there is no maximally excellent being is a non-modal sentence, then wouldnt it follow that maximal greatness cant possibly be exemplified?

It would follow if it is true that There is no maximally excellent being. But it wouldnt follow if it is false.
A maximally great being must exist in a maximally excellent way in every possible world. So if there is no maximally excellent being, then obviously a maximally great being does not exist. If a maximally great beings existence is even possible, then it exists in every possible world, including this one. So if it does not exist, it is not possible that it exist.
I wonder if there is some confusion on your part about what a modal sentence is. A modal sentence includes some sort of modal operator like Necessarily, . . . or Possibly, . . . . But a non-modal sentence can still be necessarily true or necessarily false. For example, 2+2=4 is non-modal sentence, as is Gold has the atomic number 79, but both are necessarily true. So the non-modal sentence There is no maximally excellent being may still be necessarily false. Indeed, if a maximally great being is even possible, that non-modal sentence is necessarily false.
The problem of evil aside, theres no good reason to think that a maximally excellent being does not exist. Perhaps the more interesting question is whether its possible that a maximally excellent being does not exist. You might think so. But our modal intuitions on that question will be parasitic on whether we think its possible that a maximally great being exists. Proponents of the ontological argument think that it is possible and, accordingly, that the sentence Possibly, a maximally excellent being does not exist is false.
