In this extract from Book 4 chapter 1 of Victor Hugo's Les Miserables, Javert feels the strain of the true, innate conscience bursting his brain as he recognizes the absolute goodness of Jean Valjean. Javert is torn between his duty as a policeman and his inner knowledge that something has been awakened, what Aquinas would call synderesis or knowledge of first principles. The first principle of all is to do good and avoid evil, and Javert is faced with the stark choice – do good or follow the way of duty. He gazes into the Seine. Will he jump?

Javert leaned both elbows on the parapet, his chin resting in both hands, and, while his nails were mechanically twined in the abundance of his whiskers, he meditated.

A novelty, a revolution, a catastrophe had just taken place in the depths of his being; and he had something upon which to examine himself.

Javert was undergoing horrible suffering.

For several hours, Javert had ceased to be simple. He was troubled; that brain, so limpid in its blindness, had lost its transparency; that crystal was clouded. Javert felt duty divided within his conscience, and he could not conceal the fact from himself. When he had so unexpectedly encountered Jean Valjean on the banks of the Seine, there had been in him something of the wolf which regains his grip on his prey, and of the dog who finds his master again.

He beheld before him two paths, both equally straight, but he beheld two; and that terrified him; him, who had never in all his life known more than one straight line. And, the poignant anguish lay in this, that the two paths were contrary to each other. One of these straight lines excluded the other. Which of the two was the true one?

His situation was indescribable.

To owe his life to a malefactor, to accept that debt and to repay it; to be, in spite of himself, on a level with a fugitive from justice, and to repay his service with another service; to allow it to be said to him, "Go," and to say to the latter in his turn: "Be free"; to sacrifice to personal motives duty, that general obligation, and to be conscious, in those personal motives, of something that was also general, and, perchance, superior, to betray society in order to remain true to his conscience; that all these absurdities should be realized and should accumulate upon him,–this was what overwhelmed him.

One thing had amazed him,–this was that Jean Valjean should have done him a favor, and one thing petrified him,– that he, Javert, should have done Jean Valjean a favor.
Where did he stand? He sought to comprehend his position, and could no longer find his bearings.

What was he to do now? To deliver up Jean Valjean was bad; to leave Jean Valjean at liberty was bad. In the first case, the man of authority fell lower than the man of the galleys, in the second, a convict rose above the law, and set his foot upon it. In both cases, dishonor for him, Javert. There was disgrace in any resolution at which he might arrive. Destiny has some extremities which rise perpendicularly from the impossible, and beyond which life is no longer anything but a precipice. Javert had reached one of those extremities.

Thought on any subject whatever, outside of the restricted circle of his functions, would have been for him in any case useless and a fatigue; thought on the day which had just passed was a torture. Nevertheless, it was indispensable that he should take a look into his conscience, after such shocks, and render to himself an account of himself.

Was it not a fearful thing that Javert and Jean Valjean, the man made to proceed with vigour, the man made to submit,–that these two men who were both the things of the law, should have come to such a pass, that both of them had set themselves above the law? What then! Such enormities were to happen and no one was to be punished! Jean Valjean, stronger than the whole social order, was to remain at liberty, and he, Javert, was to go on eating the government's bread!

His revery gradually became terrible.

Jean Valjean disconcerted him. A benevolent malefactor, merciful, gentle, helpful, clement, a convict, returning good for evil, giving back pardon for hatred, preferring pity to vengeance, preferring to ruin himself rather than to ruin his enemy, saving him who had smitten him, kneeling on the heights of virtue, more nearly akin to an angel than to a man. Javert was constrained to admit to himself that this monster existed.

Things could not go on in this manner.

Then his reflections reverted to himself and beside Jean Valjean glorified he beheld himself, Javert, degraded.

A convict was his benefactor!

His supreme anguish was the loss of certainty. He felt that he had been uprooted. The code was no longer anything more than a stump in his hand. He had to deal with scruples of an unknown species. There had taken place within him a revelation of inner feeling entirely distinct from legal affirmation, his only standard of measurement hitherto. To remain in his former uprightness did not suffice. A whole order of unexpected facts had cropped up and subjugated him. A whole new world was dawning on his soul: kindness accepted and repaid, devotion, mercy, indulgence, violences committed by pity on austerity, respect for persons, no more definitive condemnation, no more conviction, the possibility of a tear in the eye of the law, no one knows what justice according to God, running in inverse sense to justice according to men. He perceived amid the shadows the terrible rising of an unknown moral sun; it horrified and dazzled him. An owl forced to the gaze of an eagle.

He found that he was a coward. He conceived a horror of himself.

Javert's ideal, was not to be human, to be grand, to be sublime; it was to be irreproachable.
Now, he had just failed in this.

How had he come to such a pass? How had all this happened? He could not have told himself. He clasped his head in both hands, but in spite of all that he could do, he could not contrive to explain it to himself.

This new chief, God, he became unexpectedly conscious of, and he felt embarrassed by him. This unforeseen presence threw him off his bearings; he did not know what to do with this superior, he, who was not ignorant of the fact that the subordinate is bound always to bow, that he must not disobey, nor find fault, nor discuss, and that, in the presence of a superior who amazes him too greatly, the inferior has no other resource than that of handing in his resignation.

But how was he to set about handing in his resignation to God?

A terrible situation! To be touched.

To be granite and to doubt! To be the statue of Chastisement cast in one piece in the mould of the law, and suddenly to become aware of the fact that one cherishes beneath one's breast of bronze something absurd and disobedient which almost resembles a heart! To come to the pass of returning good for good, although one has said to oneself up to that day that that good is evil!

That which was passing in Javert was the Fampoux of a rectilinear conscience, the derailment of a soul, the crushing of a probity which had been irresistibly launched in a straight line and was breaking against God. It certainly was singular that the stoker of order, that the engineer of authority, mounted on the blind iron horse with its rigid road, could be unseated by a flash of light! that the immovable, the direct, the correct, the geometrical, the passive, the perfect, could bend! that there should exist for the locomotive a road to Damascus!

God, always within man, and refractory, He, the true conscience, to the false; a prohibition to the spark to die out; an order to the ray to remember the sun; an injunction to the soul to recognize the veritable absolute when confronted with the fictitious absolute, humanity which cannot be lost; the human heart indestructible; that splendid phenomenon, the finest, perhaps, of all our interior marvels, did Javert understand this? Did Javert penetrate it? Did Javert account for it to himself? Evidently he did not. But beneath the pressure of that incontestable incomprehensibility he felt his brain bursting.
