The two had been close since Malcolm's surgery. Harding had been on a sabbatical year in Austin, and had helped nurse Malcolm back to health, after his many operations. For a while it seemed as if a romance had blossomed, and that Malcolm, a confirmed bachelor, would settle down. But then Harding had gone back to Africa, and Malcolm had gone to Santa Fe. Whatever their former relationship had been, they were now just friends.

They discussed the questions that had come at the end of his lecture. From Malcolm's point of view, there had been only the predictable objections: that mass extinctions were important; that human beings owed their existence to the Cretaceous extinction, which had wiped out the dinosaurs and allowed the mammals to take over. As one questioner had pompously phrased it, "The Cretaceous allowed our own sentient awareness to arise on the planet."

Malcom's reply was immediate: "What makes you think human beings are sentient and aware? There's no evidence for it. Human beings never think for themselves they find it too uncomfortable. For the most part, members of our species simply repeat what they are told -and become upset if they are exposed to any different view. The characteristic human trait is not awareness but conformity, and the characteristic result is religious warfare. Other animals fight for territory or food; but, uniquely in the animal kingdom, human beings fight for their 'beliefs.' The reason is that beliefs guide behavior, which has evolutionary importance among human beings. But at a time when our behavior may, well lead us to extinction, I see no reason to assume we have any awareness at all. We are stubborn, self-destructive conformists. Any other view of our species is just a self-congratulatory delusion. Next question."

Now, walking across the courtyard, Sarah Harding laughed. "They didn't care for that."
