“So our lives
In acts exemplary, not only win
Ourselves good names, but doth to others give
Matter for virtuous deeds, by which we live.”

Ramblings In Cheapside (1890)
Context: All we know is, that even the humblest dead may live along after all trace of the body has disappeared; we see them doing it in the bodies and memories of these that come after them; and not a few live so much longer and more effectually than is desirable, that it has been necessary to get rid of them by Act of Parliament. It is love that alone gives life, and the truest life is that which we live not in ourselves but vicariously in others, and with which we have no concern. Our concern is so to order ourselves that we may be of the number of them that enter into life — although we know it not.

The trial of Charles B. Reynolds for blasphemy (1887)
Context: Gentlemen, you can never make me believe — no statute can ever convince me, that there is any infinite Being in this universe who hates an honest man. It is impossible to satisfy me that there is any God, or can be any God, who holds in abhorrence a soul that has the courage to express his thought. Neither can the whole world convince me that any man should be punished, either in this world or in the next, for being candid with his fellow-men. If you send men to the penitentiary for speaking their thoughts, for endeavoring to enlighten their fellows, then the penitentiary will become a place of honor, and the victim will step from it — not stained, not disgraced, but clad in robes of glory.
Let us take one more step.
What is holy, what is sacred? I reply that human happiness is holy, human rights are holy. The body and soul of man — these are sacred. The liberty of man is of far more importance than any book; the rights of man, more sacred than any religion — than any Scriptures, whether inspired or not.
What we want is the truth, and does any one suppose that all of the truth is confined in one book — that the mysteries of the whole world are explained by one volume?
All that is — all that conveys information to man — all that has been produced by the past — all that now exists — should be considered by an intelligent man. All the known truths of this world — all the philosophy, all the poems, all the pictures, all the statues, all the entrancing music — the prattle of babes, the lullaby of mothers, the words of honest men, the trumpet calls to duty — all these make up the bible of the world — everything that is noble and true and free, you will find in this great book.
If we wish to be true to ourselves, — if we wish to benefit our fellow-men — if we wish to live honorable lives — we will give to every other human being every right that we claim for ourselves.

Excerpts from the two paragraphs above have sometimes been quoted in abbreviated form: At the risk of seeming ridiculous, let me say that the true revolutionary is guided by a great feeling of love. It is impossible to think of a genuine revolutionary lacking this quality... We must strive every day so that this love of living humanity will be transformed into actual deeds, into acts that serve as examples, as a moving force.
Man and Socialism in Cuba (1965)
Context: At the risk of seeming ridiculous, let me say that the true revolutionary is guided by a great feeling of love. It is impossible to think of a genuine revolutionary lacking this quality. Perhaps it is one of the great dramas of the leader that he or she must combine a passionate spirit with a cold intelligence and make painful decisions without flinching. Our vanguard revolutionaries must idealize this love of the people, of the most sacred causes, and make it one and indivisible. They cannot descend, with small doses of daily affection, to the level where ordinary people put their love into practice.
The leaders of the revolution have children just beginning to talk, who are not learning to call their fathers by name; wives, from whom they have to be separated as part of the general sacrifice of their lives to bring the revolution to its fulfilment; the circle of their friends is limited strictly to the number of fellow revolutionists. There is no life outside of the revolution.
In these circumstances one must have a great deal of humanity and a strong sense of justice and truth in order not to fall into extreme dogmatism and cold scholasticism, into isolation from the masses. We must strive every day so that this love of living humanity will be transformed into actual deeds, into acts that serve as examples, as a moving force.
