Re: Basic question on co- and contra-variance
I agree that it can be stated in terms of duality but the terms covariant/contravariant are due to the coordinate transformations and are essentially geometric, more than algebric. Of course, the product isn't "inner" if you consider it as between V and V*, it only becomes inner if you consider V as being self-dual.
I think Sanctus was concerned less with the math than with finding something beyond it.
