The Forgotten Temple *honor text box blah* Limited: Target your discarded Nonhuman Personality and discard a card in one of your provinces: Refill the province face-up with the Personality
Rulebook The Dead: Special rules cover Personality cards in the discard pile. A Personality who is destroyed in play enters the discard pile in the dead state; the card is turned 90° in the pile, or otherwise set apart from other discarded cards there, and remains that way while there.
Am I correct to say that The Forgotten Temple makes no distinction between dead and discarded personalities in your discard pile and therefore allows you to place a dead Nonhuman back into a province to be replayed?

No, you are not.
Discarded (emphasis mine): "The state of a card in the discard pile that is not dead, regardless of how it got in the discard pile."
