In his preamble to the 1277 condemnations, Tempier accuses the philosophers of maintaining philosophical stances irreconcilable with Catholic dogmas while at the same time upholding their Catholic faith. Modern historians called this the "double truth" theory, the idea of the existence of two simultaneous yet contradictory truths: a factual or "hard" truth that is reached through science and philosophy, and a "religious" truth that is reached through religion. This idea differed from that of Averroes: he taught that there is only one truth, but reached in two different ways, not two truths. He did however believe that Scripture sometimes uses metaphorical language, but that those without the philosophical training to appreciate the true meaning of the passages in question were obliged to believe the literal meaning.
