'But we are not cruel, if we can avoid it, and do not kill without need. If there was some way we could live in peace and well-fed contentment, we would throw away our spears and never kill again. But no one has ever shown us how to do this, if such a way exists.' A gleam came into his eyes such as Sylviana had not seen for many months: when he first looked out from the smaller cave, and beheld the power and majesty of the Mantis. 'Go ahead,' he told them, almost defiantly. 'Ask me any question. Thank you Kataya, and David Rawlings. You have made me feel strong and unashamed.' At this there was another brief space in which the company felt reluctant to speak. But it did not last. Their desire to know, and to touch new life, was stronger than their natural timidity. 'Yes, I have a question,' said a woman. 'You say that your people have no spoken language.' (Sylviana had told the doctor, who in turn had passed it on to the others). 'And yet you have a name. How is that?' 'My people all have names, but no sounds to go with them. My name is a sign made with the hands, or a figure drawn in the dirt, so that I can be identified to others at need, such as during a hunt. The Machine called me Kalus, to my mind as well as my ears, just as it gave names to all the elements of my world. I have always wondered how this was done.' Brushing over this last information, which none understood and which they could always come back to, they asked several more questions about the hill-people, until one of the younger men produced a greaseboard and marker, and approached him. 'Your sign, the one that identifies you. Could you draw it?' Kalus took the board, and after being shown how to use it, drew a straight line, horizontal, then a long curving tooth like a saber at the end of it, pointing downward. 'This represents the upper jaw of the hill-cat, one of the greatest hunters of our world. My first father made it for me, hoping that I would be as fierce and cunning. All our names our similar. When he was killed by a bear. . .I drew it in anger on the ground, then with my foot blurred away the sharp point, to show that I was no great predator, but only a man. Like this.' He smeared the lower half of the tusk, leaving only a squarish root. 'That has been my mark ever since.' 'The MANtooth,' said Sylviana suddenly, and much to her own consternation. But half embarrassed, half proud in spite of herself, she pushed on. 'The Machine called you the Mantooth.' 'Yes,' he said simply. 'And that is what I am.' 'This machine---' began another. 'No, no, we'll come back to that later,' said Rawlings. 'Your ‘first father', Kalus. What did you mean by that?'
