Many schools of thought as to "where we are today". I'd go with Wittgenstein's formulation: that logic "underpins" mathematics in the same way a painted foundation underpins a painted castle (RFM). From my standpoint, Russell is enduring because of his wrestling with the "real world" issues of the day, such as whether to fight Hitler or to retreat into the isolationism of post-WW1. He took ethical positions. I don't think most hyper-specialists practicing today have anything close to his courage and wouldn't call them "philosophers" for the most part (I don't accept self-labeling as veridical, only time will tell). British philosophy in general was more creditable back then, when there were still the remnants of a 113 year-old empire. American analytic schools have no such gravitas, and indeed were undermined by the later Wittgenstein. The "American empire" has mostly midgets who bask in reflected light. Kirby
