Rawls, Turing & Searle, Singer

It's our last class of the semester in CoPhi, wrapping up with John Rawls, Alan Turing, John Searle (who's lately joined an ignoble list of alleged philosopher/harassers, but that's another topic), and Peter Singer.

Rawls' "stroke of genius" was his Original Position thought experiment, seeking fairness and justice (for Rawls justice is fairness) via the imaginative contrivance of a "veil of ignorance." The idea is to acknowledge and lessen the undue influence of special interest pleading in our politics, allowing only those inequalities of wealth, status, privilege, opportunity, and resources that benefit all. The least well-off must be better off, when the veil is lifted, than otherwise. [SoL video]

Alan Turing's Imitation Game, "proposing the practical test of whether or not we would attribute intelligence to a system whose performance is indistinguishible from that of a human agent," says if it walks and talks like a smart duck it practically is one. John Searle countered with the Chinese Room, which "purports to show that even effective computer simulations do not embody genuine intelligence, since rule-governed processes need not rely upon understanding by those who perform them."

But some philosophers remain convinced that  we might someday use computers to achieve virtual immortality. That didn't work out so well for Johnny Depp in Transcendence. "I can't feel anything," says the uploaded semblance of his former self. If that's the singularity I hope it's nowhere near, Ray Kurzweil. "Transcending biology" might strip us of our humanity and not replace it with anything better.

Peter Singer says we should always be prepared to sacrifice "one or two of the luxuries that we don't really need" to help strangers. When you put it that way it doesn't really sound like "a hard philosophy to live up to," much as we love our branded shoes and suits, our cars and college funds, and our carnivorous ways. "But that doesn't mean Singer is wrong about what we ought to do." We ought to do a great deal more good for those in need than we do, most of us. Maybe we ought to stop eating sentient animals. Certainly we ought to stop inflicting gratuitous pain on all who can feel it. We ought to be less selfish and more cooperative.


Singer "represents the very best tradition in philosophy," if you agree that "constantly challenging widely held assumptions" like Socrates is the very best tradition. Kwame Anthony Appiah basically agrees, but would modify Singer's principle to something like: “if you are the best person in the best position to prevent something really awful, and it won’t cost you much to do so, do it.” [Singer slides]

We could say more, but there's a little exam we're itching to get on with. Suffice for now to say what Professor James always says on the last day of every class, as he said the last time he said anything at all. In the words of his favorite pluralistic mystic, “there is no conclusion. What has concluded, that we might conclude in regard to it? There are no fortunes to be told, and there is no advice to be given. — Farewell!”

Actually there is one important bit of advice all philosophers will endorse:
Albert Einstein
Learn from yesterday, live for today, hope for tomorrow. The important thing is not to stop questioning. #Einstein

And then there's some good advice about how to prepare for an exam.

And since it's poet Ted Kooser's birthday I'll add one more thing. Like Anthony Trollope, who said “A small daily task, if it be really daily, will beat the labors of a spasmodic Hercules,” Kooser had a habit of "rising early every morning so he could write for an hour and a half before going to the office." He wrote seven books that way, and became poet laureate. So the advice (which James also gave, notwithstanding his parting reluctance to say so) is: form good daily work habits and stick to 'em. "How we spend our days is how we spend our lives." -Annie Dillard

Good luck!
