So it was the belief in Maker that founded healing magic ? Medicine ? Construction ? Printing Press ? Writing ? Transportation ? Forging ? I think not my dear.
If you want to look at it that way; Well the first true schools of magic were employed by the Imperium after its conquest of the old elven empire, the circles as we know them came to be after Andraste toppled the Imperium and led the way to the Chantry, so Healing magic as it exists now?
Exists solely because of the belief in the Maker.
Construction? Well let's look back shall we?
Prior to the Second Blight; and even after it building was a crude and unrefined process, sure harp the Imperium all you wish, but the point remains that the buildings constructed back then didn't have the modern practices, belief and material of modern builders, the Imperium had centuries in which to improve this practices prior to the arrival of Andraste, and while some of their buildings have weathered, most have not, while on the other hand?
You have non dwarven structures constructed after the first and second blight, that still stand are in decent repair.
So is their a direct correlation? I suppose you could argue it.
The printing press well that is something of a matter of debate no? I mean the Dwarves invented that before the arrival of Andraste, so its hardly relevant to the argument, i mean if it doesn't exist at least until the cult of the maker, then how could the followers of the beliefs of said faith actually do anything about it?
Writing or at least some takes on written language is also a gift from the dwarves.
Transportation? Well this goes back to the issue of buildings to be honest, vessels have certainly improved in the last thousand years, and given how involved the Chantry is/was in commerce i wouldn't be surprised if they actually were behind a few innovations.
Smithing, curious you would mention that when the Chantry were the first organization to mass produce enchanting and rune crafting, by the dwarves own admission only a handful of smith houses actually bother with the art.
