4. If any one now were to say that those things which happen to us from an external cause, and call forth our movements, are of such a nature that it is impossible to resist them, whether they incite us to good or evil, let the holder of this opinion turn his attention for a little upon himself, and carefully inspect the movements of his own mind, unless he has discovered already, that when an enticement to any desire arises, nothing is accomplished until the assent of the soul is gained, and the authority of the mind has granted indulgence to the wicked suggestion; so that a claim might seem to be made by two parties on certain probable grounds as to a judge residing within the tribunals of our heart, in order that, after the statement of reasons, the decree of execution may proceed from the judgment of reason. For, to take an illustration: if, to a man who has determined to live continently and chastely, and to keep himself free from all pollution with women, a woman should happen to present herself, inciting and alluring him to act contrary to his purpose, that woman is not a complete and absolute cause or necessity of his transgressing, since it is in his power, by remembering his resolution, to bridle the incitements to lust, and by the stern admonitions of virtue to restrain the pleasure of the allurement that solicits him; so that, all feeling of indulgence being driven away, his determination may remain firm and enduring. Finally, if to any men of learning, strengthened by divine training, allurements of that kind present themselves, remembering forthwith what they are, and calling to mind what has long been the subject of their meditation and instruction, and fortifying themselves by the support of a holier doctrine, they reject and repel all incitement to pleasure, and drive away opposing lusts by the interposition of the reason implanted within them.
