Judgment would be the faculty of the frontier. A detailed reading of the introduction to the Critique of Judgment and of the Critique of Teleological Judgment shows Kant developing a radically subjective thought of natural purposiveness that must take precedence over the scientific or objective investigation of nature. This thought necessarily leads, however, beyond nature to theological questions. Kant’s effort to think these through and thus to throw a bridge over the abyss (a radical figure of what we have been calling “frontier”) between the legislations of theoretical and practical reason is shown to founder on the structure of teleology itself, which, as was already suggested in the strictly political writings, necessarily involves a moment of hesitation or interruption that essentially cuts teleology from its telos, and that just is the structure of the frontier as we have been following it from the beginning.
