QUOTE : Apparently at every stage of mental development, save the highest of all, the mind's growing point is tender and easily misdirected. However this may be, it is a fact that a few rather highly developed worlds, even with communal mentality, were disastrously perverted in a strange manner, which I find very difficult to understand. I can only suggest that in them, seemingly, the hunger for true community and true mental lucidity itself became obsessive and perverse, so that the behavior of these exalted perverts might deteriorate into something very like tribalism and religious fanaticism. The disease would soon lead to stifling of all elements which seemed recalcitrant to the generally accepted culture of the world-society. When such worlds mastered interstellar travel, they might conceive a fanatical desire to impose their own culture throughout the galaxy. Sometimes their zeal became so violent that they were driven to wage ruthless wars on all who resisted them.
