How to easily defeat any argument for God

[Belacqua]

That’s no easy task, i don’t think anything we can say could full capture the meaning of Good. Our recognition of it is less a matter of hearing or saying, but seeing.

Like a 3 month old who sees something good about the person who helps another, rather than the one who hinders another persons, absent of any language to articulate it.

Perhaps our best attempts to articulate it are expressed in art

Yes, I agree that as limited humans there is no statement or definition we could give to describe the fullness of the Good. In fact I think this is one of the reasons people say God -- as a kind of placeholder for this unsayable thing.

And I have sympathy for the apophatic theologians, who warn that a sentence like "God is the Good" is misleading and therefore dangerous. Because it implies that we know what the Good is, and therefore can give a limited definition to an infinite thing. Or ascribe an attribute to God, who doesn't have attributes. 

And I agree that art -- or other things in the world which strike us with their beauty or other types of appeal -- are the best handles we have to approach understanding. This is why Dante is saved by Beatrice, and not a book of theology.

I’m weary of happiness as an aim, because happiness is fleeting. If you were happy all the time, there’s probably something wrong with you.

I’d replace happiness with meaning. Because meaning transcends both happiness and unhappiness, both suffering and the lack of it. The Good is what satisfies the human longing for meaning. While not perfect, I’d prefer it to your suggestion.

The people I most admire are not necessarily happy, and the period in which I’ve admired them the most are in times of tragedy and suffering in their lives, when they’re not necessarily happy, but times in which they seem to exist with some sort profound sense of meaning, that transcends both their suffering and sadness.

Granted, happiness is problematic. (But it served to get the ball rolling here.) Clearly we'd want to distinguish between happiness and pleasure. There are other words which might be better -- maybe fulfillment, or the actualization of our full humanness. Something like that. 

But look at it this way: to me, having meaning may well point to some further goal. I want meaning (as in, the inscribed messages of the world) so that I can understand the world, and I want to understand the world so... something -- a further goal. Or, for a different sense of meaning (more like purpose) I want meaning so that I feel my life is well-lived, with a good purpose. And I want my life to be well-lived so that.... something. 

So we could remove the word happiness, and replace it with something more philosophical like "that goal in life beyond which there is no further goal." "That thing which, if attained, is a complete fulfillment of one's life." It sounds happy to me, though not in a dance-dance Coca-Cola commercial sense of happiness. And I'd say that this is what theologians call God.
