As for the dinosaur - But Noah's conscience was easy; it was not named in his cargo list and he and the boys were not aware that there was such a creature. He said he could not blame himself for not knowing about the dinosaur, because it was an American animal and America had not then been discovered.
Does the human being reason? No; he thinks, muses, reflects, but does not reason...that is, in the two things which are the peculiar domain of the heart, not the mind, politics and religion. He doesn't want to know the other side. He wants arguments and statistics for his own side, and nothing more.
