Udayana's Nyaya Kusumanjali is a Nyaya-Vaisheshika work which seeks to logically prove the existence of God. In this excerpt from the Nyaya Kusumanjali, Udayana describes how the Prana Pratishtha ritual makes the presence of a Deva enter a statue:
The deities become conciliated in the ceremonies of consecration, and show it by coming to take up their residence, i.e. by the appropriation of the image and self-consciousness thereto; but by the touch of an impure person such appropriation and self-consciousness are rendered void. Even on the Mimansaka view which disputes the intelligence of the deities, we can say that it is the idea that the worship has been performed in a due manner, and that the image has been duly consecrated, - this idea also being necessarily accompanied by the absence of the touch of any impure person, - which constitutes the image's fitness as an object of worship, and the ceremony's importance lies in its contributing to produce the idea
I asked about the "impure person" part in my question here, but now I'm interested in the part in bold. My question is, is it true that the Purva Mimamsa school believed that the Devas had no intelligence, i.e. no capacity to think?
Now as I discuss in this answer, the Purva Mimamsa school believed a lot a strange things about the Devas: that they don't have bodies, that they do not consume offerings made in Yagnas, that they're not allowed to do Yagnas themselves, and that the only role they play in Yagnas is that offerings are made with reference to them as recipients. And in this excerpt from his commentary on the Purva Mimamsa Sutras, Shabaraswami says that it would not hurt the Purva Mimamsa position if someone said that the Devas are just words:
Says the Opponent - "In that case it is the word that becomes the Deity." Answer - This is an idea that it is not for us to refute; because such an idea, if expressed, does not militate against our view; on the contrary it lends all the more strength to the view [that different names of the same Deva should not be substituted for one another].
But are there any Purva Mimamsa works which say that the Devas have no intelligence?
