The Ontological Argument for the Existence of God

[Reflex]

But aren't you assuming there is a sensible way to interpret ‘maximally great being’ which will have the persuasive force you think it will?  More likely, there isn't.

I am assuming that a sensible person must have some understanding of the history of terms use before daring to critique them.

In this forum? Are you kidding? A 'sensible person' here is about as rare as hairs on a frog.
