"Certainly, as everyone has pointed out, the manner, if not the substance, of James's thinking was specifically and uniquely American. The American lust for movement and acquisition fills the sails of his style and thought, and gives them a buoyant and almost aerial motility. Huneker calls it “a philosophy for philistines,” and indeed there is something that smacks of salesmanship in it: James talks of God as of an article to be sold to a materialistically-minded consumer by every device of optimistic advertising; and he counsels us to believe as if he were recommending long-term investments, with high dividends, in which there was nothing to lose, and all the (other) world to win. It was young America's defense-reaction against European metaphysics and European Science...When some pragmatists speak of a belief having been true once because they were useful (though now disproved), they utter nonsense learnedly; it was a useful error, not a truth. Pragmatism is correct only if it is a platitude."
