“He [Eugène Rougon] believed exclusively in himself; where another saw reasons, Rougon possessed convictions; he subordinated everything to the incessant aggrandisement of his own ego. Despite being utterly devoid of real self-indulgence, he nevertheless indulged in secret orgies of supreme power.”

“The chief reason why the prince was so particularly disagreeable to Vronsky was that he could not help seeing himself in him. And what he saw in this mirror did not gratify his self-esteem. He was a very stupid and very self-satisfied and very healthy and very well-washed man, and nothing else... He was equable and not cringing with his superiors, was free and ingratiating in his behavior with his equals, and was contemptuously indulgent with his inferiors... for this prince he was an inferior, and his contemptuous and indulgent attitude to him revolted him.”

“The very freedom which the sinner supposedly exercises in his self-indulgence is only another proof that he is ruled by the tyrant.”

“He was persuaded he could know no happiness but in the society of one with whom he could for ever indulge the melancholy that had taken possession of his soul.”

“For a moment he [Doctor Pascal] thought he could see, in a flash, the future of the Rougon-Macquart family, a pack of wild, satiated appetites in the midst of a blaze of gold and blood.”

“Novelty and Security: the security of novelty, the novelty of security. Always the full thing, the whole subject, the true subject, stood just behind the one you found yourself contemplating. The trick, but it wasn't a trick, was to take up at once the thing you saw and the reason you saw it as well; to always bite off more than you could chew, and then chew it. If it were self-indulgence for him to cut and polish his semiprecious memories, and yet seem like danger, like a struggle he was unfit for, then self-indulgence was a potent force, he must examine it, he must reckon with it.”
