As wickedness is quite consistent with reason, and in deed only becomes really terrible in this conjunction, so, conversely, nobleness is sometimes joined with want of reason. To this may be attributed the action of Coriolanus, who, after he had applied all his strength for years to the accomplishment of his revenge upon the Romans, when at length the time came, allowed himself to be softened by the prayers of the Senate and the tears of his mother and wife, gave up the revenge he had so long and so painfully prepared, and indeed, by thus bringing on himself the just anger of the Volscians, died for those very Romans whose thanklessness he knew and desired so intensely to punish. Finally, for the sake of completeness, it may be mentioned that reason may very well exist along with want of understanding. This is the case when a foolish maxim is chosen, but is followed out consistently. An example of this is afforded by the case of the Princess Isabella, daughter of Philip II., who vowed that she would not put on a clean chemise so long as Ostend remained unconquered, and kept her word through three years. In general all vows are of this class, whose origin is a want of insight as regards the law of causality, i.e., want of understanding; nevertheless it is rational to fulfil them if one is of such narrow understanding as to make them.
In agreement with what we have said, we see the writers who appeared just before Kant place the conscience, as the seat of the moral impulses, in opposition to the reason. Thus Rousseau, in the fourth book of "Emile," says: "La raison nous trompe, mais la conscience ne trompe jamais;" and further on: "Il est impossible d'expliquer par les conséquences de notre nature le principe immediat de la conscience indépedant de la raison même." Still further: "Mes sentimens naturels parlaient pour l'intérêt commun, ma raison rapportait tout a moi. ... On a beau vouloir etablir la vertu
at all. To reproach Machiavelli with the immorality of his writing is just the same as to reproach a fencing-master because he does not begin his instructions with a moral lecture against murder and slaughter.
