Calvin had thoughts about Le Fou
John Calvin on Psalm 14:1
They [ed: fools] may not plainly deny the existence of a God, but they imagine him to be shut up in heaven, and divested of his righteousness and power; and this is just to fashion an idol in the room of God. As if the time would never come when they will have to appear before him in judgment, they endeavor, in all the transactions and concerns of their life, to remove him to the greatest distance, and to efface from their minds all apprehension of his majesty. And when God is dragged from his throne, and divested of his character as judge, impiety has come to its utmost height; and, therefore, we must conclude that David has most certainly spoken according to truth, in declaring that those who give themselves liberty to commit all manner of wickedness, in the flattering hope of escaping with impunity, deny in their heart that there is a God.
