“He realized at last that the arguments of pessimism were powerless to comfort him”

“Like a tide-race, the waves of human mediocrity are rising to the heavens and will engulf this refuge, for I am opening the flood-gates myself, against my will. Ah! but my courage fails me and my heart is sick within me! -- Lord, take pity on the Christian who doubts, on the unbeliever who would fain believe, on the galley-slave of life who puts out to sea alone, in the night, beneath a firmament no longer lit by the consoling beacon-fires of the ancient hope!"(A Rebours, final words) ”

“His contempt for humanity grew fiercer, and at last he came to realize that the world is made up mostly of fools and scoundrels. It became perfectly clear to him that he could entertain no hope of finding in someone else the same aspirations and antipathies; no hope of linking up with a mind which, like his own, took pleasure in a life of studious decrepitude; no hope of associating an intelligence as sharp and wayward as his own with any author or scholar.”

“What I want to do is to teach a lesson to all these people … I want [to prove] that the Devil exists, that the Devil reigns supreme, that the power he enjoyed in the Middle Ages has not been taken from him, for today he is the absolute master of the world.”

“...he shrunk more and more from the realities of life and above all from the society of his day which he regarded with an ever growing horror,--a detestation which had reacted strongly on his literary and artistic tastes; he refused, as far as possible, to have anything to do with pictures and books whose subjects were in any way connected with modern existence.”

“And Harry saw very clearly as he sat there under the hot sun how people who cared about him had stood in front of him one by one, his mother, his father, his godfather, and finally Dumbledore, all determined to protect him; but now that was over. He could not let anybody else stand between him and Voldemort; he must abandon forever the illusion he ought to have lost at the age of one, that the shelter of a parent’s arms meant that nothing could hurt him. There was no waking from this nightmare, no comforting whisper in the dark that he was safe really, that it was all in his imagination; the last and greatest of his protectors had died, and he was more alone than he had ever been.”
