Forgive me for bubbling this one back up but I'm still looking for that word

Incidentally speaking of Buddhism, I wonder if anyone familiar with it might not agree that one of Zen's unspoken tenets is that mental health depends upon being able to entertain conflicting ideas

This is especially true in conventional religion, where faith is de facto the ability to believe something having no basis in fact

But getting back to the word I'm seeking, might a successful mind-cure might not also strongly depend on the foregoing ability
