2_d_. That, in reality, a just principle is lurking under Kant's error; but a principle translated from its proper ground. Not truth, individual or personal--not truth of mere facts, but truth doctrinal--the truth which teaches, the truth which changes men and nations--this is the truth concerned in Kant's meaning, had he explained his own meaning to himself more distinctly. With respect to that truth, wheresoever it lies, Kant's doctrine applies--that all men have a right to it; that perhaps you have no right to suppose of any race or nation that it is not prepared to receive it; and, at any rate, that no circumstances of expedience can justify you in keeping it back. CASE VI. THE CASE OF CHARLES I. Many cases arise from the life and political difficulties of Charles I. But there is one so peculiarly pertinent to an essay which entertains the general question of Casuistry--its legitimacy, its value--that with this, although not properly a domestic case, or only such in a mixed sense, we shall conclude. No person has been so much attacked for his scruples of conscience as this prince; and what seems odd enough, no person has been so much attacked for resorting to books of Casuistry, and for encouraging literary men to write books of Casuistry. Under his suggestion and sanction, Saunderson wrote his book on the obligation of an oath, (for which there was surely reason enough in days when the democratic tribunals were forcing men to swear to an _et caetera_;) and, by an impulse originally derived from him, Jeremy Taylor wrote afterwards his _Ductor Dubitantium_, Bishop Barlow wrote his _Cases of Conscience_, &c. &c.
