"Without being too clinical, let’s say his brain was affected."

“How large was mankind’s sense of obligation? The caveman first had this feeling for his mate, then for his family. It grew until men fought and died for the abstract ideas of cities and nations, then for whole planets. Would the time ever come when men might realize that the obligation should be to the largest and most encompassing reality of all—mankind? And beyond that to life of all kinds.”

“A kiss is a contact, a union, an exchange. It is unknown to certain races and tribes, while others know it and consider it with disgust. They all suffer a loss. A kiss can be a cold formula, or a token of familial relationship or a prelude to the act of love. It can also be a revelation in an unspoken, secret language of feelings that have never been expressed in words.”

“The final product is a man-plant-animal symbiote that is admirably adapted for survival on this disaster world. No emotions to cause complications or desires that might interfere with pure survival. Complete ruthlessness—mankind has always been strong on this anyway, so it didn’t take much of a push.”

“Cold-blooded killing is just not my thing. I've killed in self-defence, I'll not deny that, but I still maintain an exaggerated respect for life in all forms. Now that we know that the only thing on the other side of the sky is more sky, the idea of an afterlife has finally been slid into the history books alongside the rest of the quaint and forgotten religions. With heaven and hell gone we are faced with the necessity of making a heaven or hell right here. What with societies and metatechnology and allied disciplines we have come a long way and life on the civilised worlds is better than it was during the black days of superstition. But with the improving of here and now comes the stark realisation that here and now is all we have. Each of us has only this one brief experience with the bright light of consciousness in that endless dark night of eternity and must make the most of it. Doing this means we must respect the existence of everyone else and the most criminal act imaginable is the terminating of one of these conscious existences.”
