Mary had also taught that the human brain was the most admirable survival device yet produced by evolution. But now her own big brain was urging her to take the polyethylene garment bag from around a red evening dress in her closet, and to wrap it around her head, thus depriving her cells of oxygen.
Before that, her wonderful brain had entrusted a thief at the airport with a suitcase containing all her toilet articles and clothes which would have been suitable for the hotel.
Her colossal thinking machine could be so petty, too. It would not let her go downstairs in her combat fatigues on the grounds that everybody, even though there was practically nobody in the hotel, would find her comical in such a costume. Her brain told her: ‘They’ll laugh at you behind your back, and think you’re crazy and pitiful, and your life is over anyway. You’ve lost your husband and your teaching job, and you don’t have any children or anything else to live for, so just put yourself out of your misery with the garment bag. What could be easier? What could be more painless? What could make more sense?’
Just about every adult human being back then had a brain weighing about three kilogrammes! There was no end to the evil schemes that a thought machine that oversized couldn’t imagine and execute.
So I raise this question, although there is nobody around to answer it: Can it be doubted that three-kilogramme brains were once nearly fatal defects in the evolution of the human race?
