Three days after the presidential election, an astute law professor tweeted a picture of three paragraphs, very slightly condensed, from Richard Rorty’s “Achieving Our Country,” published in 1998. It was retweeted thousands of times, generating a run on the book — its ranking soared on Amazon and by day’s end it was no longer available. (Harvard University Press is reprinting the book for the first time since 2010, a spokeswoman for the publisher said.)

It’s worth rereading those tweeted paragraphs:

[M]embers of labor unions, and unorganized unskilled workers, will sooner or later realize that their government is not even trying to prevent wages from sinking or to prevent jobs from being exported. Around the same time, they will realize that suburban white-collar workers — themselves desperately afraid of being downsized — are not going to let themselves be taxed to provide social benefits for anyone else. At that point, something will crack. The nonsuburban electorate will decide that the system has failed and start looking around for a strongman to vote for — someone willing to assure them that, once he is elected, the smug bureaucrats, tricky lawyers, overpaid bond salesmen, and postmodernist professors will no longer be calling the shots. … One thing that is very likely to happen is that the gains made in the past 40 years by black and brown Americans, and by homosexuals, will be wiped out. Jocular contempt for women will come back into fashion. … All the resentment which badly educated Americans feel about having their manners dictated to them by college graduates will find an outlet.

Mr. Rorty, an American pragmatist philosopher, died in 2007. Were he still alive, he’d likely be deluged with phone calls from strangers, begging him to pick their stocks.

When “Achieving Our Country” came out, it received a mixed critical reception. Writing for this newspaper, the critic Christopher Lehmann-Haupt called the book “philosophically rigorous” but took umbrage at Mr. Rorty’s warnings about the country’s vulnerability to the charms of a strongman, calling this prophesy “a form of intellectual bullying.”

Donald J. Trump enthusiasts might dispute the word strongman. But the essence of Mr. Rorty’s argument holds up surprisingly well. Where others saw positive trends — say, a full-throated dawn chorus praising the nation’s diversity — Mr. Rorty saw dead canaries in a coal mine.
