My point is that if your cosmological paradigm is that any philosophy can have divine power without a discrete being associated with it, fitting in a cleric made around the assuption of a specific deity is trivial, since you can merely explain that it is not the discrete divinity that provides the power, but the belief in the philosophy.
Understood.
OTOH, fitting a cleric conceived with the idea that any belief can yield power independant of a divine entity to a campaign that assumes you require a discrete entity to grant divine power is non-trivial, since the disctrete entity you would have to fit might contradict the history of divinities in the game, may not fit a pre-defined division of portfolios, and will lack the background that grounds the religion in the campaign that other clerics will have.
Got it. I recognize the discrepancy that you are refering to:
In the first instance, there is limitless divine energy, while in the second, divinity is limited. In the case of an infinite amount of philosophies or causes, there can always be a new philosophy that can be born. In the case of a limited amount of gods, then there are only so many sources of divine power.
So the problem, from my perspective, is not the philosophy/diety split, but the amount of divine power, be it infinite or finite.
If I were to build a cosmology that is both limited and philosophical (maybe there are only a few ideas that can grant divine inspiration), the exact same problem would occur.
For example: If there is
only Bushido and the Tao, and these are the only two philosophies that can grant divine spells in all of existence, then a player who wants a character of a different philosophy is out of luck. They are stuck with whatever portfolios Bushido and the Tao provide.
I'm guessing this is what you have been trying to explain all along and I was just being obtuse. Please correct me if I am wrong.

Well, that is not my major point, but that is part of it. How would you suggest the PHB address this, if at all?
That's just it. I wouldn't have the PHB address this. Rule Zero is already blatant enough. It is the DM's job to change whatever they want and tell the players beforehand. Players, IMX, have multiple ideas for characters, and are not going to get upset if you explain the world (and the options available) to them previous to character creation.
If you say, "No orcs! No evil! No godless clerics!" before they make characters, then they won't make those (unless they are petty.) *grin*
