“It was in the attempt to ascertain the interrelationships between species that experiments n genetics were first made. The words "evolution" and "origin of species" are now so intimately associated with the name of Darwin that we are apt to forger that the idea of common descent had been prominent in the mnds of naturalists before he wrote, and that, for more than half a century, zealous investigators had been devoting themselves to the experimental study of that possibility. Prominent among this group of experimenters may be mentioned Koelreauter, John Hunter, Herbert Knight, Gartner, Jordan. Naudin, Godron, Lecoq, Wichura--men whose names are familiar to every reader of Animals and Plants unders Domestication.”

“We have to accept that any action we take might promote an equal and opposite reaction that we do not want. We have to realize that even the most noble actions or most obviously correct course can have its dark side that we cannot control or reason our way out of. The fighter of the "just war" must understand that her actions will result in the deaths of other humans; many of whom may be innocent. The pacifist who refuses all war must realize that his inaction might likewise result in the deaths of the innocent. There are no actions without contradiction—and yet we must act, for not to act is also a contradictory action with both positive and negative effects.”
