Another dead tree from the Randwick City Library. Second time around, and just as good. Here he is on zombie ideas (p106):
Ideas are the oldest software virus, the history of ideas being written by those fortunate enough to get born into enough physical and mental spare time to think beyond food and shelter and the protection of those they love, always blind to the resulting bias, the resultant imbalance of perspective. Ideas kill and maim as many children as any epidemic, they mutate and reappear as new strains, now immune to the propaganda that killed them off a generation ago, the science of actively combating a virulent idea being still rarely more sophisticated than crude attacks on the hardware, the meat. "Enlightened" people claim ideas should be free to spread and compete in our soft minds, always, you'll find if you really talk to them, with the exception of one or two ideas considered beyond the pale to people like them for no consistent reason beyond their mounting rage and fear as they spray you with the reinforcing dinner-party repartee of their peers, the soothing commentary and opinion published in broadsheets and parroted by the gazette brains of public broadcasters and the social and political satirist "comedians" who comfort them all in their othodoxy.
