According to James, if “no practical differences whatever can be traced” between two opposing ideas, then they “mean practically the same thing, and all dispute is idle.” Can you think of any important opposing ideas that make no real “practical difference”? For example, is there a real practical difference between being a Lutheran and being a Catholic? Between being a Democrat and being a Republican? Think of some opposing ideas similar to these but that you think have no real “practical differences.” Even if opposing ideas have no real “practical differences,” does it follow that they must “mean” the same? Why?
