@philip klocking: I'm a little startled to see the sublime used in this context; isn't the notion of the sublime a descriptive term in art or aesthetics? Not that I'm disagreeing with what your saying - speculative thought is sublime only when its connected to practical too.

In the third critique, the feeling of the sublime is linked to the moral feeling, respect. See philosophy.stackexchange.com/questions/3499/… - and yes, it is part of Kant's aesthetics, including the aesthetics of morals.
