“Hate is a bottomless cup; I will pour and pour.” Euripides, Medea
“["F]or it's not possible," [Socrates] said, "for anybody to experience a greater evil than hating arguments. Hatred of arguments and hatred of human beings come about in the same way. For hatred of human beings arises from artlessly trusting somebody to excess, and believing that human being to be in every way true and sound and trustworthy, and then a little later discovering that this person is wicked and untrustworthy - and then having this experience again with another. And whenever somebody experiences this many times, and especially at the hands of just those he might regard as his most intimate friends and comrades, he then ends up taking offense all the time and hates all human beings and believes there's nothing at all sound in anybody.” Plato, Phaedo
“In time we hate that which we often fear.” Shakespeare, Cleopatra.
"Nature seems (the more we look into it) made up of antipathies: without something to hate, we should lose the very spring of thought and action. Life would turn to a stagnant pool, were it not ruffled by the jarring interests, the unruly passions, of men. ...
"The pleasure of hating, like a poisonous mineral, eats into the heart of religion, and turns it to rankling spleen and bigotry; it makes patriotism an excuse for carrying fire, pestilence, and famine into other lands: it leaves to virtue nothing but the spirit of censoriousness, and a narrow, jealous, inquisitorial watchfulness over the actions and motives of others. ...
"In private life do we not see hypocrisy, servility, selfishness, folly, and impudence succeed, while modesty shrinks from the encounter, and merit is trodden under foot? How often is "the rose plucked from the forehead of a virtuous love to plant a blister there!" What chance is there of the success of real passion? What certainty of its continuance? Seeing all this as I do, and unravelling the web of human life into its various threads of meanness, spite, cowardice, want of feeling, and want of understanding, of indifference towards others, and ignorance of ourselves, - seeing custom prevail over all excellence, itself giving way to infamy - mistaken as I have been in my public and private hopes, calculating others from myself, and calculating wrong; always disappointed where I placed most reliance; the dupe of friendship, and the fool of love; - have I not reason to hate and to despise myself? Indeed I do; and chiefly for not having hated and despised the world enough." Wm. Hazlitt, The Pleasure of Hating“Loving someone is different from being in love with someone. You can hate someone you're in love with.” Dostoyevsky, The Brothers Karamazov
“[O]ne captain, seizing the line-knife from his broken prow, had dashed at the whale, as an Arkansas duelist at his foe, blindly seeking with a six-inch blade to reach the fathom-deep life of the whale. That captain was Ahab.” Melville, Moby Dick
“One does not hate as long as one has a low esteem of someone, but only when one esteems him as an equal or a superior.” - Nietzsche, Beyond Good and Evil
“Suddenly, by the sort of violent effort with which one wrenches one's head away from the pillow in a nightmare, Winston succeeded in transferring his hatred from the face on the screen to the dark−haired girl behind him. Vivid, beautiful hallucinations flashed through his mind. He would flog her to death with a rubber truncheon. He would tie her naked to a stake and shoot her full of arrows like Saint Sebastian. He would ravish her and cut her throat at the moment of climax. Better than before, moreover, he realized why it was that he hated her. He hated her because she was young and pretty and sexless, because he wanted to go to bed with her and would never do so, because round her sweet supple waist, which seemed to ask you to encircle it with your arm, there was only the odious scarlet sash, aggressive symbol of chastity.” Orwell, 1984
"Hate of the object involves hate of oneself, you suffer with the object you attack because you cannot give up the object and feel one with it. …
"What is the meaning of hate? It is not the absolute opposite of love; that would be indifference, having no interest in a person, not wanting a relationship and so having no reason for either loving or hating, feeling nothing. Hate is love grown angry because of rejection. We can only really hate a person if we want their love. Hate is an expression of frustrated love needs, an attempt to destroy the bad rejecting side of a person in the hope of leaving their good responsive side available, a struggle to alter them. The anxiety is over the danger of hate destroying both sides, and the easiest way out is to find two objects and love one and hate the other." H. Guntrip, "A Study of Fairbairn's Theory of Schizoid Reactions," p. 351, Psychopathology: A Source Book, ed. Charles Frederick Reed.
