And now, after having been with the tribe--the only human tribe--for over a year, he was being balked by this--priest! Which meant being balked at setting up Truth and Knowledge as the only true gods of humanity, being balked at getting the dam built before the spring rains, so that there would not be another summer drouth followed by a winter of famine such as they had just passed through. The dam was his first big project; without freedom from want, there would be little progress next winter. Almost savagely he turned on Thougor. "But why must you have this religious festival _now_?" "Because of the finding of the god Thor," came Thougor’s cold answer. "Why the offerings of blood? Can’t they wait? The dam _must_ be finished before the rains; but the loss of blood already has so weakened the workers that they can no longer work for a full day." "Which is more important, worldly or spiritual things?" Thougor replied. "But there maybe won’t be anyone around to indulge in spiritual things if there’s another drouth this year!" "Thor will see to it that there is not another drouth." "Yes, I know, but wouldn’t it be wiser to be on the safe side? Suppose somebody does something to displease Thor?" "Nobody will displease Thor! It is my duty to see to that! I tell them what to think, so that they won’t displease Thor." _A crafty devil you are_, Builder thought. _Manipulating this image of Thor you talk about, so that it will take the blood offerings of the people and even you and that half-baked discipline of yours, Morge. I must look at your god Thor one of these days--_ He suddenly felt very weary and sat down on the floor; looking up at Thougor, he said, "But that is not part of being civilized, to tell the people _what_ to think. You must _make_ them think without telling them what to think. And with the dam, next winter there will be freedom from want for the first time. The tribe will have a chance to think and be on the road to civilization." "The tribe has already found civilization in finding Thor. By worshipping Him as a group they have already ceased their bickering and quarreling. Does not that fit in with your definition of civilization, the one you gave my people when you first came to us? Since the coming of Thor we have begun to cooperate, have we not?" "No, hardly at all. I said civilization is cooperation among men in adapting to environment--which includes man." The two men stared at each other, and for awhile there was silence. "Nevertheless," Thougor finally said, "Thor and blood offerings continue!" Builder watched Thougor turn and stalk out of the tiny hovel that housed his plans and his work, himself and his dreams. What could he do? He could only appeal to the tribe’s reason; Thougor could appeal to their emotions which were far stronger. But unless emotion was controlled, used wisely, there could never be any reason.
