Do we have enemies inside us? can we be destroyed by ourselves? do we have to be on guard against parts of...?

ourselves? simple error can kill us? and we have a faculty unique among animals of clinging to our level of development? we think we have a right to stay the same, hold rigidly to our opinions in defiance of reality? which is like the right to be blind? the right of a sapling to stay a sapling? we alone among the animals suffer from closedmindedness? feeling we have a right to blindness? it is hard enough to get hold of reality without handicapping ourselves with unopenness to data? instead of ensuring our survival by closedness, we ensure our destruction? adaptation, response is the name of the living game? taking in is creativity aliveness fertility life? i guess a bigot is a hypermale: doesnt want to be screwed by anything, not even data? the bigot is a rigid virgin, sterile? 'we come closest to truth when we hear all opinions'? 'test everythng & hold on to what seems good' [bible] & keep testing it? the engineer keeps testing the train wheels? we're still 98% chimps, arent we??
