Emil Cioran has some good ones:
"The same feeling of not belonging, of futility, wherever I go: I pretend interest in what matters nothing to me, I bestir myself mechanically or out of charity, without ever being caught up, without ever being somewhere. What attracts me is elsewhere, and I don't know where that elsewhere is."
"What I know at sixty, I knew as well at twenty. Forty years of a long, a superfluous, labor of verification."
"I get along quite well with someone only when he is at his lowest point and has neither the desire nor the strength to restore his habitual illusions."
"Better to be an animal than a man, an insect than an animal, a plant than an insect, and so on.
Salvation? Whatever diminishes the kingdom of consciousness and compromises its supremacy."
"I have always struggled, with the sole intention of ceasing to struggle. Result: zero."
"I have never taken myself for a being. A non-citizen, a marginal type, a nothing who exists only by the excess, by the superabundance of his nothingness."
"As far as I am concerned, I resign from humanity. I no longer want to be, nor can still be, a man. What should I do? Work for a social and political system, make a girl miserable? Hunt for weaknesses in philosophical systems, fight for moral and esthetic ideals? It's all too little. I renounce my humanity even though I may find myself alone. But am I not already alone in this world from which I no longer expect anything?"
As does Thomas Ligotti:
"For the rest of the earth's organisms, existence is relatively uncomplicated. Their lives are about three things: survival, reproduction, death—and nothing else. But we know too much to content ourselves with surviving, reproducing, dying—and nothing else. We know we are alive and know we will die. We also know we will suffer during our lives before suffering—slowly or quickly—as we draw near to death. This is the knowledge we "enjoy" as the most intelligent organisms to gush from the womb of nature. And being so, we feel shortchanged if there is nothing else for us than to survive, reproduce, and die. We want there to be more to it than that, or to think there is. This is the tragedy: Consciousness has forced us into the paradoxical position of striving to be unself-conscious of what we are—hunks of spoiling flesh on disintegrating bones."
"Within the hierarchy of fabrications that compose our lives—families, countries, gods—the self incontestably ranks highest. Just below the self is the family, which has proven itself more durable than national or ethnic affiliations, with these in turn outranking god-figures for their staying power. So any progress toward the salvation of humankind will probably begin from the bottom—when our gods have been devalued to the status of refrigerator magnets or lawn ornaments. Following the death rattle of deities, it would appear that nations or ethnic communities are next in line for the boneyard. Only after fealty to countries, gods, and families has been shucked off can we even think about coming to grips with the least endangered of fabrications—the self."
"How much nonsense can we take in our lives? And is there any way we can escape it? No, there is not. We are doomed to all kinds of nonsense: the pain nonsense, the nightmare nonsense, the sweat and slave nonsense, and many other shapes and sizes of insufferable nonsense. It is brought to us on a plate, and we must eat it up or face the death nonsense."
"So they trust in the deity of the Old Testament, an incontinent dotard who soiled Himself and the universe with his corruption, a low-budget divinity passing itself off as the genuine article. (Ask the Gnostics.) They trust in Jesus Christ, a historical cipher stitched together like Frankenstein's monster out of parts robbed from the graves of messiahs dead and buried - a savior on a stick. They trust in the virgin-pimping Allah and his Drum Major Mohammed, a prophet-come-lately who pioneered a new genus of humbuggery for an emerging market of believers that was not being adequately served by existing religious products. They trust in anything that authenticates their importance as persons, tribes, societies, and particularly as a species that will endure in this world and perhaps in an afterworld that may be uncertain in its reality and unclear in its layout, but which states their craving for values "not of this earth" - that depressing, meaningless place their consciousness must sidestep every day."
"Also worthy of mention is a clique among the suicidal for whom the meaning of their act is a darker thing. Frustrated as perpetrators of an all-inclusive extermination, they would kill themselves only because killing it all is closed off to them. They hate having been delivered into a world only to be told, by and by, "This way to the abattoir, Ladies and Gentlemen." They despise the conspiracy of Lies for Life almost as much as they despise themselves for being a party to it. If they could unmake the world by pushing a button, they would do so without a second thought. There is no satisfaction in a lonesome suicide. The phenomenon of "suicide euphoria" aside, there is only fear, bitterness, or depression beforehand, then the troublesomeness of the method, and nothingness afterward. But to push that button, to depopulate this earth and arrest its rotation as well—what satisfaction, as of a job prettily done. This would be for the good of all, for even those who know nothing about the conspiracy against the human race are among its injured parties."
"Compassion for human hurt, a humble sense of our impermanence, an absolute valuation of justice—all of our so-called virtues only trouble us and serve to bolster, not assuage, horror. In addition, these qualities are our least vital, the least in line with life. More often than not, they stand in the way of one's rise in the welter of this world, which found its pace long ago and has not deviated from it since. The putative affirmations of life—each of them based on the propaganda of Tomorrow: reproduction, revolution in its widest sense, piety in any form you can name—are only affirmations of our desires. And, in fact, these affirmations affirm nothing but our penchant for self-torment, our mania to preserve a demented innocence in the face of gruesome facts.
By means of supernatural horror we may evade, if momentarily, the horrific reprisals of affirmation. Every one of us, having been stolen from nonexistence, opens his eyes on the world and looks down the road at a few convulsions and a final obliteration. What a weird scenario. So why affirm anything, why make a pathetic virtue of a terrible necessity? We are destined to a fool's fate that deserves to be mocked. And since there is no one else around to do the mocking, we will take on the job. So let us indulge in cruel pleasures against ourselves and our pretensions, let us delight in the Cosmic Macabre. At least we may send up a few bitter laughs into the cobwebbed corners of this crusty old universe."
