There is in certain living souls a quality of loneliness unspeakable, so great it must be shared as company is shared by lesser beings. Such a loneliness is mine; so know by this that in immensity there is one lonelier than you.

There is an invincible taste for prostitution in the heart of man, from which comes his horror of solitude. He wants to be 'two'. The man of genius wants to be 'one'... It is this horror of solitude, the need to lose oneself in the external flesh, that man nobly calls 'the need to love'.

... What does it mean to be lonely? How do we live, if we're not intimately engaged with another human being? How do we connect with other people, particularly if we don't find speaking easy? Is sex a cure for loneliness, and if it is, what happens if our body or sexuality is considered deviant or damaged, if we are ill or unblessed with beauty? And is technology helping with these things? Does it draw us together, or trap us behind screens?

Loneliness is emptiness; and moral nature has as much horror of it as physical nature. Solitude is habitable only for the man of genius who fills it with his ideas — daughters of the spiritual world — or for the beholder of divine works who finds it illuminated by the day of heaven, animated by the breath and by the voice of God. Save these two men, so close to paradise, loneliness is to torture what morale is to physique. Between loneliness and torture there is all the difference between nervous illness and surgical illness. It is suffering multiplied by infinity. The body touches infinity through the nervous system, just as the mind enters it through thought.

A sense of utter loneliness—loneliness inevitable, crushing, eternal, the loneliness of existence, encompassed by the infinite void of unconsciousness—enfolded him as a pall. Life lay like an incubus on his bosom. He shuddered at the thought that death might overlook him, and deny him its refuge.

Who knows what true loneliness is — not the conventional word, but the naked terror? To the lonely themselves it wears a mask. The most miserable outcast hugs some memory or some illusion.

Man ordinarily lives in loneliness. To avoid loneliness, he creates all kinds of relationships, friendships, organizations, political parties, religions and what not. But the basic thing is that he is very much afraid of being lonely. Loneliness is a black hole, a darkness, a frightening negative state almost like death … as if you are being swallowed by death itself. To avoid it, you run out and fall into anybody, just to hold somebody’s hand, to feel that you are not lonely… Nothing hurts more than loneliness.
But the trouble is, any relationship that arises out of the fear of being lonely is not going to be a blissful experience, because the other is also joining you out of fear. You both call it love. You are both deceiving yourself and the other. It is simply fear, and fear can never be the source of love. Only those who love are absolutely fearless; only those who love are able to be alone, joyously, whose need for the other has disappeared, who are sufficient unto themselves…

The day you decide that all these efforts are failures, that your loneliness has remained untouched by all your efforts, that is a great moment of understanding. Then only one thing remains: to see whether loneliness is such a thing that you should be afraid of, or if it is just your nature. Then rather than running out and away, you close your eyes and go in. Suddenly the night is over, and a new dawn … The loneliness transforms into aloneness.

Aloneness is your nature. You were born alone, you will die alone. And you are living alone without understanding it, without being fully aware of it. You misunderstand aloneness as loneliness; it is simply a misunderstanding. You are sufficient unto yourself.

The experiences of a man who lives alone and in silence are both vaguer and more penetrating than those of people in society; his thoughts are heavier, more odd, and touched always with melancholy. Images and observations which could easily be disposed of by a glance, a smile, an exchange of opinion, will occupy him unbearably, sink deep into the silence, become full of meaning, become life, adventure, emotion. Loneliness ripens the eccentric, the daringly and estrangingly beautiful, the poetic. But loneliness also ripens the perverse, the disproportionate, the absurd, and the illicit.

It’s loneliness. Even though I’m surrounded by loved ones who care about me and want only the best, it’s possible they try to help only because they feel the same thing — loneliness — and why, in a gesture of solidarity, you’ll find the phrase “I am useful, even if alone” carved in stone. Though the brain says all is well, the soul is lost, confused, doesn’t know why life is being unfair to it. But we still wake up in the morning and take care of our children, our husband, our lover, our boss, our employees, our students, those dozens of people who make an ordinary day come to life. And we often have a smile on our face and a word of encouragement, because no one can explain their loneliness to others, especially when we are always in good company. But this loneliness exists and eats away at the best parts of us because we must use all our energy to appear happy, even though we will never be able to deceive ourselves. But we insist, every morning, on showing only the rose that blooms, and keep the thorny stem that hurts us and makes us bleed hidden within. Even knowing that everyone, at some point, has felt completely and utterly alone, it is humiliating to say, “I’m lonely, I need company. I need to kill this monster that everyone thinks is as imaginary as a fairy-tale dragon, but isn’t.” But it isn’t. I wait for a pure and virtuous knight, in all his glory, to come defeat it and push it into the abyss for good, but that knight never comes. Yet we cannot lose hope. We start doing things we don’t usually do, daring to go beyond what is fair and necessary. The thorns inside us will grow larger and more overwhelming, yet we cannot give up halfway. Everyone is looking to see the final outcome, as though life were a huge game of chess. We pretend it doesn’t matter whether we win or lose, the important thing is to compete. We root for our true feelings to stay opaque and hidden, but then … … instead of looking for companionship, we isolate ourselves even more in order to

Loneliness, she thought, was craving for other people's company. But she did not know that loneliness can be an unnoticed cramping of the spirit for lack of companionship.

I do not know which impulse was stronger in me when I began to think: the original thirst for knowledge or the urge to communicate with man. Knowledge attains its full meaning only through the bond that unites men; however, the urge to achieve agreement with another human being was so hard to satisfy. I was shocked by the lack of understanding, paralyzed, as it were, by every reconciliation in which what had gone before was not fully cleared up. Early in my life and then later again and again I was perplexed by people’s rigid inaccessibility and their failure to listen to reasons, their disregard of facts, their indifference which prohibited discussion, their defensive attitude which kept you at a distance and at the decisive moment buried any possibility of a close approach, and finally their shamelessness, that bares its own soul without reserve, as though no one were present. When ready assent occurred I remained unsatisfied, because it was not based on true insight but on yielding to persuasion; because it was the consequence of friendly cooperation, not a meeting of two selves. True, I knew the glory of friendship (in common studies, in the cordial atmosphere of home or countryside). But then came the moments of strangeness, as if human beings lived in different worlds. Steadily the consciousness of loneliness grew upon me in my youth, yet nothing seemed more pernicious to me than loneliness, especially the loneliness in the midst of social intercourse that deceives itself in a multitude of friendships. No urge seemed stronger to me than that for communication with others. If the never-completed movement of communication succeeds with but a single human being, everything is achieved. It is a criterion of this success that there be a readiness to communicate with every human being encountered and that grief is felt whenever communication fails. Not merely an exchange of words, nor friendliness and sociability, but only the constant urge towards total revelation

When we are most alone is when we embrace another's loneliness.

Loneliness does not come from having no people about one, but from being unable to communicate the things that seem important to oneself, or from holding certain views which others find inadmissible.
