In short, I think the problem with Lakoff’s ideas are two fold: 1) the science is probably wrong, so it has little utilitarian value aside from enriching Lakoff 2) the false perception that the science is correct and can be used to persuade people basically leaves liberals totally vulnerable to being laughed at (a lot of the stuff that Lakoff acolytes say about the Right is giggle-inducing! Pinker is describing a real phenomenon, as I’ve chuckled myself). If I was a particularly partisan non-liberal I would probably let it rest, as it is good for the Right for the Left to hold to Lakoff closely, just as it is good for the Left for Christian fundamentalists to continue speaking like raving Bible-thumpers outside of their own circles. But in the end politics is epiphenomenal, the truth shall outlive us all, and only one culture has spawned science in the history of our species. That demands our reverence (at least mine) far more than who will win in 2006, or 2026.
