I've always had the highest respect for John Rawls, but reading his Lectures on the History of Political Philosophy has shot his approval ratings sky-high for me. Forget about the minutiae of the Difference Principle, the maximin argument, and all that. Rawls's treatment of the Greats is sufficient to establish him as a world-class philosophical mind.
Here's an intriguing throwaway comment that Rawls makes while discussing Mill:
[Mill] also supposes that we have a permanent interest in knowing the truth. He doesn't entertain the dark thought that one finds in Russian novelists such as Dostoyevsky: witness Ivan's tale of the Grand Inquisitor . . ., that knowing the truth would be horrible, making us disconsolate and ready to support a dictatorial regime to preserve our comforting and necessary illusions. St. Augustine and Dostoyevsky are the two dark minds in Western thought, and the former has shaped it profoundly.
I've checked the index, and this is the only mention of Augustine in the entire book. I know very little about Augustine. Does anyone care to take a guess at what in Augustine Rawls is alluding to here? What's the connection between the Dostoyevsky point and Augustine?
