“I don't know how to be silent when my heart is speaking.” — Fyodor Dostoyevsky
Kierkegaard’s warning to those fixated on knowledge and meaning-making to their detriment:
“I have tasted the fruit of the tree of knowledge, and often delighted in its taste. But the pleasure did not outlast the moment of understanding and left no profound mark upon me.”
“What would be the use of discovering so-called objective truth, of working through all the systems of philosophy and of being able, if required, to review them all and show up the inconsistencies within each system; — what good would it do me to be able to develop a theory of the state and combine all the details into a single whole, and so construct a world in which I did not live, but only held up to the view of others; — what good would it do me to be able to explain the meaning of Christianity if it had no deeper significance for me and for my life ; — what good would it do me if truth stood before me, cold and naked, not caring whether I recognised her or not, and producing in me a shudder of fear rather than a trusting devotion?”
“It is the divine side of man, his inward action which means everything, not a mass of information; for that will certainly follow and then all that knowledge will not be a chance assemblage, or a succession of details, without system and without a focusing point. I too have certainly looked for such a centre. I have looked in vain for an anchorage in the boundless sea of pleasure and in the depth of understanding; I have felt the almost irresistible power with which one pleasure reaches out its hand to the next; I have felt the sort of meretricious ecstasy that it is capable of producing, but also the ennui and the distracted state of mind that succeeds it.”
Soren Kierkegaard on what is a poet and the nature of critics/reviewers from Either/Or, A Fragment of Life (1843):
“What is a poet? An unhappy person who conceals profound anguish in his heart but whose lips are so formed that as sighs and cries pass over them they sound like beautiful music.
It is with him as with the poor wretches in Phalaris’s bronze bull, who were slowly tortured over a slow fire; their screams could not reach the tyrant’s ears to terrify him; to him they sounded like sweet music. And people crowd around the poet and say to him, “Sing again soon”— in other words, may new sufferings torture your soul, and may your lips continue to be formed as before, because your screams would only alarm us, but the music is charming.
And the reviewers step up and say, “That is right; so it must be according to the rules of aesthetics.” Now of course a reviewer resembles a poet to a hair, except that he does not have the anguish in his heart, or the music on his lips. Therefore, I would rather be a swineherd out on Amager and be understood by swine than be a poet and be misunderstood by people.”
Kierkegaard says that in the modern world we don't even have the courage to off ourselves:
“Not even a suicide these days does away with himself in desperation but deliberates on this step so long and so sensibly that he is strangled by calculation, making it a moot point whether or not he can really be called a suicide, inasmuch as it was in fact the deliberating that took his life. A premeditated suicide he was not, but rather a suicide by means of premeditation.” 
He had something we deeply lack in the modern world—a cause worth dying for, a strong moral conscience and the ability to transcend death by realising the hell we are nurturing because of inaction in the here and now; action—even if, death—is justified. 
“We should not pretend to understand the world only by the intellect. The judgement of the intellect is only part of the truth.”
— Carl Jung
“One who makes himself a worm cannot complain afterwards if people step on him.” — Immanuel Kant
“I am a sick man...I am a spiteful man. I am an unattractive man. I believe my liver is diseased.” –– Fyodor Dostoevsky, Notes from Underground
“Destroy my desires, eradicate my ideals, show me something better, and I will follow you.” — Fyodor Dostoevsky
“There exists no greater or more painful anxiety for a man who has freed himself from all religious bias, than how he shall soonest find a new object or idea to worship. But man seeks to bow before that only which is recognized by the greater majority, if not by all his fellow-men, as having a right to be worshipped; whose rights are so unquestionable that men agree unanimously to bow down to it. For the chief concern of these miserable creatures is not to find and worship the idol of their own choice, but to discover that which all others will believe in, and consent to bow down to in a mass. It is that instinctive need of having a worship in common that is the chief suffering of every man, the chief concern of mankind from the beginning of times. It is for that universality of religious worship that people destroyed each other by sword. Creating gods unto themselves, they forwith began appealing to each other: "Abandon your deities, come and bow down to ours, or death to ye and your idols!" And so will they do till the end of this world; they will do so even then, when all the gods themselves have disappeared, for then men will prostrate themselves before and worship some idea. Thou didst know, Thou couldst not be ignorant of, that mysterious fundamental principle in human nature, and still thou hast rejected the only absolute banner offered Thee, to which all the nations would remain true, and before which all would have bowed—the banner of earthly bread, rejected in the name of freedom and of "bread in the kingdom of God"! Behold, then, what Thou hast done furthermore for that "freedom's" sake! I repeat to Thee, man has no greater anxiety in life than to find some one to whom he can make over that gift of freedom with which the unfortunate creature is born.” — Fyodor Dostoyevsky, The Grand Inquisitor
“I did not bow down to you, I bowed down to all the suffering of humanity.” — Fyodor Dostoevsky

“Yes; we will make them work like slaves, but during their recreation hours they shall have an innocent child-like life, full of play and merry laughter. We will even permit them sin, for, weak and helpless, they will feel the more love for us for permitting them to indulge in it. We will tell them that every kind of sin will be remitted to them, so long as it is done with our permission; that we take all these sins upon ourselves, for we so love the world, that we are even willing to sacrifice our souls for its satisfaction. And, appearing before them in the light of their scapegoats and redeemers, we shall be adored the more for it. They will have no secrets from us. It will rest with us to permit them to live with their wives and concubines, or to forbid them, to have children or remain childless, either way depending on the degree of their obedience to us; and they will submit most joyfully to us the most agonizing secrets of their souls—all, all will they lay down at our feet, and we will authorize and remit them all in Thy name, and they will believe us and accept our mediation with rapture, as it will deliver them from their greatest anxiety and torture—that of having to decide freely for themselves. And all will be happy, all except the one or two hundred thousands of their rulers. For it is but we, we the keepers of the great Mystery who will be miserable.” — Fyodor Dostoevsky, The Grand Inquisitor
“Liberty, Freedom of Thought and Conscience, and Science will lead them into such impassable chasms, place them face to face before such wonders and insoluble mysteries, that some of them—more rebellious and ferocious than the rest—will destroy themselves; others—rebellious but weak—will destroy each other; while the remainder, weak, helpless and miserable, will crawl back to our feet and cry: "'Yes; right were ye, oh Fathers of Jesus; ye alone are in possession of His mystery, and we return to you, praying that ye save us from ourselves!" Receiving their bread from us, they will clearly see that we take the bread from them, the bread made by their own hands, but to give it back to them in equal shares and that without any miracle; and having ascertained that, though we have not changed stones into bread, yet bread they have, while every other bread turned verily in their own hands into stones, they will be only to glad to have it so. Until that day, they will never be happy.” — Fyodor Dostoyevsky, The Grand Inquisitor
“And who can rule mankind better than those who have possessed themselves of man's conscience, and hold in their hand man's daily bread?” — Fyodor Dostoevsky
Shame and Guilt are soul-eating emotions; former thrives under the shallow mass-hallucinative insanity of the society, and the latter feeds away at our inner core, hijacking our notion of "goodness" and binds it to something irrelevant, ephemeral, rather than something eternal.
“There are three Powers, three unique Forces upon earth, capable of conquering for ever by charming the conscience of these weak rebels—men—for their own good; and these Forces are: Miracle, Mystery and Authority.” — Fyodor Dostoyevsky, The Grand Inquisitor
“I suffer from life and from other people. I can’t look at reality face to face. Even the sun discourages and depresses me. Only at night and all alone, withdrawn, forgotten and lost, with no connection to anything real or useful — only then do I find myself and feel comforted.” — Fernando Pessoa
"To annihilate [the self], to give it over completely to each and to all undividedly and selflessly. And this is the greatest happiness." –– The Unpublished Dostoevsky: Diaries & Notebooks
“For the mystery of human being does not solely rest in the desire to live, but in the problem—for what should one live at all? Without a clear perception of his reasons for living, man will never consent to live, and will rather destroy himself than tarry on earth, though he be surrounded with bread. This is the truth.” — Fyodor Dostoyevsky
