The discipline of pure reason in dogmatic use Since we have made it our duty to determine the bounds of pure rea son in transcendental use exactly and with certainty, but this sort of en deavor has the peculiarity that, in spite of the most pressing and clearest warnings, it still always lets itself hope that it can stave off having to give up entirely the effort to get beyond the bounds of experience into the charming regions of the intellectual, it is therefore necessary to cut away, as it were, the last anchor of a fantastical hope, and to show that the pursuit of the mathematical method in this sort of cognition cannot offer the least advantage, unless it is that of revealing its own nakedness all the more distinctly, and revealing that mathematicsO and philosophy are two entirely different things, although they offer each other their hand in natural science, thus that the procedure of the one can never be imitated by that of the other.
