So now I am alone in the world, with no brother, neighbour or friend, nor any company left me but my own.

I know nothing - nothing in the world - of the hearts of men. I only know that I am alone - horribly alone.

I feel we are all islands-in a common sea. We are all, in the last analysis, alone. When one is a stranger to oneself then one is estranged from others too. If one is out of touch with oneself, then one cannot touch others.

My passionate interest in social justice and social responsibility has always stood in curious contrast to a marked lack of desire for direct association with men and women. I am a horse for single harness, not cut out for tandem or team work. I have never belonged wholeheartedly to country or state, to my circle of friends, or even to my own family. These ties have always been accompanied by a vague aloofness, and the wish to withdraw into myself increases with the years. Such isolation is sometimes bitter, but I do not regret being cut off from the understanding and sympathy of other men. I lose something by it, to be sure, but I am compensated for it in being rendered independent of the customs, opinions, and prejudices of others, and am not tempted to rest my peace of mind upon such shifting foundations.

If I have no ties and no affections, hatred and vice must be my portion; the love of another will destroy the cause of my crimes, and I shall become a thing of whose existence every one will be ignorant. My vices are the children of a forced solitude that I abhor; and my virtues will necessarily arise when I live in communion with an equal. I shall feel the affections of a sensitive being, and become linked to the chain of existence and events, from which I am now excluded.

Each one of us is alone in the world. He is shut in a tower of brass, and can communicate with his fellows only by signs, and the signs have no common value, so that their sense is vague and uncertain. We seek pitifully to convey to others the treasures of our heart, but they have not the power to accept them, and so we go lonely, side by side but not together, unable to know our fellows and unknown by them.

When friendship disappears then there is a space left open to that awful loneliness of the outside world which is like the cold space between the planets. It is an air in which men perish utterly.

I avoided my own friends and acquaintances, yet the loneliness of my existence was insupportable.

We ask no sympathy from others in the anxiety and agony of a broken friendship or shattered love. When death sunders our nearest ties, alone we sit in the shadow of our affliction. Alike mid the greatest triumphs and darkest tragedies of life we walk alone. On the divine heights of human attainments, eulogized and worshiped as a hero or saint, we stand alone. In ignorance, poverty, and vice, as a pauper or criminal, alone we starve or steal; alone we suffer the sneers and rebuffs of our fellows; alone we are hunted and hounded through dark courts and alleys, in by-ways and highways; alone we stand in the judgment seat; alone in the prison cell we lament our crimes and misfortunes; alone we expiate them on the gallows. In hours like these we realize the awful solitude of individual life, its pains, its penalties, its responsibilities; hours in which the youngest and most helpless are thrown on their own resources for guidance and consolation. Seeing then that life must ever be a march and a battle, that each soldier must be equipped for his own protection, it is the height of cruelty to rob the individual of a single natural right.

We are like people living in a country whose language they know so little that, with all manner of beautiful and profound things to say, they are condemned to the banalities of the conversation manual. Their brain is seething with ideas, and they can only tell you that the umbrella of the gardener's aunt is in the house.

I shunned the face of man; all sound of joy or complacency was torture to me; solitude was my only consolation — deep, dark, death-like solitude.

It’s a sad thing not to have friends, but it is even sadder not to have enemies.

Let them be gone now, them and all the others, those I have used and those I have not used, give me back the pains I lent them and vanish, from my life, my memory, my terrors and shames. There, now there is no one here but me, no one wheels about me, no one comes toward me, no one has ever met anyone before my eyes, these creatures have never been, only I and this black void have ever been.
