Very many maintain that all we know is still infinitely less than all that still remains unknown; nor do philosophers pin their faith to others' precepts in such wise that they lose their liberty, and cease to give credence to the conclusions of their proper senses. Neither do they swear such fealty to their mistress Antiquity that they openly, and in sight of all, deny and desert their friend Truth.

William Harvey (born 1 April 1578) English physician

What is unique about the "I" hides itself exactly in what is unimaginable about a person. All we are able to imagine is what makes everyone like everyone else, what people have in common. The individual "I" is what differs from the common stock, that is, what cannot be guessed at or calculated, what must be unveiled, uncovered, conquered.

Milan Kundera (born 1 April 1929) Franco-Czech novelist

Forgiveness is the offspring of a feeling of heroism, of a noble heart, of a generous mind, whilst forgetfulness is only the result of a weak memory, or of an easy carelessness, and still oftener of a natural desire for calm and quietness. Hatred, in the course of time, kills the unhappy wretch who delights in nursing it in his bosom.

Giacomo Casanova (born 2 April 1725) Italian adventurer and author

My spirit to yours dear brother,
Do not mind because many sounding your name do not understand you,
I do not sound your name, but I understand you,
I specify you with joy O my comrade to salute you, and to salute those who are with you, before and since, and those to come also,
That we all labor together transmitting the same charge and succession,
We few equals indifferent of lands, indifferent of times,
We, enclosers of all continents, all castes, allowers of all theologies,
Compassionaters, perceivers, rapport of men,
We walk silent among disputes and assertions, but reject not the disputers nor any thing that is asserted,
We hear the bawling and din, we are reach'd at by divisions, jealousies, recriminations on every side,
They close peremptorily upon us to surround us, my comrade,
Yet we walk unheld, free, the whole earth over, journeying up and down till we make our ineffaceable mark upon time and the diverse eras,
Till we saturate time and eras, that the men and women of races, ages to come, may prove brethren and lovers as we are.

Walt Whitman in "To Him Who Was Crucified" in Leaves of GrassAmerican journalist and poet

Stretch or contract me, Thy poor debtor;
This is but tuning of my breast,
To make the music better. Whether I fly with angels, fall with dust,
Thy hands made both, and I am there;
Thy power and love, my love and trust
Make one place ev'rywhere.

George Herbert (born 3 April 1593) English poet and orator

The first peace, which is the most important, is that which comes within the souls of people when they realize their relationship, their oneness, with the universe and all its powers, and when they realise that at the center of the universe dwells Wakan-Tanka, and that this center is really everywhere, it is within each of us. This is the real peace, and the others are but reflections of this. The second peace is that which is made between two individuals, and the third is that which is made between two nations. But above all you should understand that there can never be peace between nations until there is known that true peace, which, as I have often said, is within the souls of men.

Black ElkA famous Medicine Man

God's own hand
Holds fast all issues of our deeds: with him
The end of all our ends is, but with us
Our ends are, just or unjust: though our works
Find righteous or unrighteous judgment, this
At least is ours, to make them righteous.

Algernon Charles Swinburne (born 5 April 1837) English poet

I learned the lesson that great men cultivate love, and that only little men cherish a spirit of hatred. I learned that assistance given to the weak makes the one who gives it strong; and that oppression of the unfortunate makes one weak.

Booker T. Washington (born 5 April 1856) American political leader, educator and author

Great minds are to make others great. Their superiority is to be used, not to break the multitude to intellectual vassalage, not to establish over them a spiritual tyranny, but to rouse them from lethargy, and to aid them to judge for themselves.

William Ellery Channing (born 7 April 1780) Unitarian preacher in the United States

There are seasons, in human affairs, of inward and outward revolution, when new depths seem to be broken up in the soul, when new wants are unfolded in multitudes, and a new and undefined good is thirsted for. There are periods when…to dare, is the highest wisdom.

William Ellery Channing (born 7 April 1780) Unitarian preacher in the United States

All their life was spent not in laws, statutes, or rules, but according to their own free will and pleasure. They rose out of their beds when they thought good: they did eat, drink, labour, sleep, when they had a mind to it, and were disposed for it. None did awake them, none did offer to constrain them to eat, drink, nor to do any other thing; for so had Gargantua established it. In all their rule, and strictest tie of their order, there was but this one clause to be observed,
DO WHAT THOU WILT.
Because men that are free, well-born, well-bred, and conversant in honest companies, have naturally an instinct and spur that prompteth them unto virtuous actions, and withdraws them from vice, which is called honour.

François Rabelais (died 9 April 1553) French humanist writer of satirical romances

They knew me from the dawn of time: if Hermes beats his rainbow wings,
If Angus shakes his locks of light, or golden-haired Apollo sings,
It matters not the name, the land; my joy in all the gods abides:
Even in the cricket in the grass some dimness of me smiles and hides.

George William Russell (born 10 April 1867) Irish nationalist, critic, poet, and painter

No greater mistake can be made than to think that our institutions are fixed or may not be changed for the worse. … Increasing prosperity tends to breed indifference and to corrupt moral soundness. Glaring inequalities in condition create discontent and strain the democratic relation. The vicious are the willing, and the ignorant are unconscious instruments of political artifice. Selfishness and demagoguery take advantage of liberty. The selfish hand constantly seeks to control government, and every increase of governmental power, even to meet just needs, furnishes opportunity for abuse and stimulates the effort to bend it to improper uses. .. The peril of this Nation is not in any foreign foe! We, the people, are its power, its peril, and its hope!

Charles Evans Hughes (born 11 April 1862) Amercian Republican politician and jurist

The only real progress to abiding peace is found in the friendly disposition of peoples and … facilities for maintaining peace are useful only to the extent that this friendly disposition exists and finds expression. War is not only possible, but probable, where mistrust and hatred and desire for revenge are the dominant motives. Our first duty is at home with our own opinion, by education and unceasing effort to bring to naught the mischievous exhortation of chauvinists; our next is to aid in every practicable way in promoting a better feeling among peoples, the healing of wounds, and the just settlement of differences.

Charles Evans Hughes (born 11 April 1862) Amercian Republican politician and jurist

No matter what you or anyone else does, there will be someone who says that there's something bad about it.
Whenever somebody comes up with a good idea, there's somebody else who has never had a good idea in his life who stands up and says, "Oh, you can't do that…"

Tom Clancy (born 12 April 1947) American author

History says don't hope
On this side of the grave.
But then, once in a lifetime
The longed for tidal wave
Of justice can rise up
And hope and history rhyme.
So hope for a great sea-change
on the far side of revenge.
Believe that a further shore
is reachable from here.
Believe in miracles
and cures and healing wells.

Seamus Heaney (born 13 April 1939) Nobel Prize-winning Irish poet

Sad hours and glad hours, and all hours, pass over;
One thing unshaken stays:
Life, that hath Death for spouse, hath Chance for lover;
Whereby decays
Each thing save one thing: — mid this strife diurnal
Of hourly change begot,
Love that is God-born, bides as God eternal,
And changes not.

James Branch Cabell (born 14 April 1879) American author of satirical fantasy works

I have read that the secret of gallantry is to accept the pleasures of life leisurely, and its inconveniences with a shrug; as well as that, among other requisites, the gallant person will always consider the world with a smile of toleration, and his own doings with a smile of honest amusement, and Heaven with a smile which is not distrustful — being thoroughly persuaded that God is kindlier than the genteel would regard as rational.

James Branch Cabell (born 14 April 1879) American author of satirical fantasy works

Experience is never limited, and it is never complete; it is an immense sensibility, a kind of huge spider-web of the finest silken threads suspended in the chamber of consciousness, and catching every air-borne particle in its tissue. It is the very atmosphere of the mind; and when the mind is imaginative — much more when it happens to be that of a man of genius — it takes to itself the faintest hints of life, it converts the very pulses of the air into revelations.

Henry James (born 15 April 1843) American-born author and literary critic

Any one who in discussion relies upon authority uses, not his understanding, but rather his memory. Good culture is born of a good disposition; and since the cause is more to be praised than the effect, I will rather praise a good disposition without culture, than good culture without the disposition.

Leonardo da Vinci (born 15 April 1452) Italian Renaissance architect, musician and painter

I am not a novelist, really not even a writer; I am a storyteller. One of my friends said about me that I think all sorrows can be borne if you put them into a story or tell a story about them, and perhaps this is not entirely untrue. To me, the explanation of life seems to be its melody, its pattern. And I feel in life such an infinite, truly inconceivable fantasy.

Karen Blixen (born 17 April 1885) Danish author

I believe that music can be an inspirational force in all our lives — that its eloquence and the depth of its meaning are all-important, and that all personal considerations concerning musicians and the public are relatively unimportant — that music come from the heart and returns to the heart — that music is spontaneous, impulsive expression — that its range is without limit — that music is forever growing — that music can be one element to help us build a new conception of life in which the madness and cruelty of wars will be replaced by a simple understanding of the brotherhood of man.

Leopold Stokowski (born 18 April 1882) Founder of the New York City Symphony Orchestra

Come unto me, all ye that labour and are heavy laden, and I will give you rest. Take my yoke upon you, and learn of me; for I am meek and lowly in heart: and ye shall find rest unto your souls. For my yoke is easy, and my burden is light.

Yeshua (Jesus Christ)Central figure of Christianity

I share the belief of many of my contemporaries that the spiritual crisis pervading all spheres of Western industrial society can be remedied only by a change in our world view. We shall have to shift from the materialistic, dualistic belief that people and their environment are separate, toward a new consciousness of an all-encompassing reality, which embraces the experiencing ego, a reality in which people feel their oneness with animate nature and all of creation.

Albert HofmannSwiss scientist

Let every one of us cultivate, in every word that issues from our mouth, absolute truth. I say cultivate, because to very few people — as may be noticed of most young children — does truth, this rigid, literal veracity, come by nature. To many, even who love it and prize it dearly in others, it comes only after the self-control, watchfulness, and bitter experience of years.

Dinah Craik (born 20 April 1826) English novelist and poet

We live in a world ruled by fictions of every kind — mass merchandising, advertising, politics conducted as a branch of advertising, the instant translation of science and technology into popular imagery, the increasing blurring and intermingling of identities within the realm of consumer goods, the preempting of any free or original imaginative response to experience by the television screen. We live inside an enormous novel. For the writer in particular it is less and less necessary for him to invent the fictional content of his novel. The fiction is already there. The writer's task is to invent the reality.

J. G. BallardBritish novelist and short story writer

How hard to realize that every camp of men or beast has this glorious starry firmament for a roof! In such places standing alone on the mountaintop it is easy to realize that whatever special nests we make — leaves and moss like the marmots and birds, or tents or piled stone — we all dwell in a house of one room — the world with the firmament for its roof — and are sailing the celestial spaces without leaving any track.

John Muir (born 21 April 1838) American environmentalist, naturalist, writer, and scientist

We have lived by the assumption that what was good for us would be good for the world. We have been wrong. We must change our lives, so that it will be possible to live by the contrary assumption that what is good for the world will be good for us. … We must recover the sense of the majesty of the creation and the ability to be worshipful in its presence. For it is only on the condition of humility and reverence before the world that our species will be able to remain in it.

Wendell BerryAmerican philosopher, poet, essayist, and social activist

I would not so dishonour God as to lend my voice to perpetuate all the mad and foolish things which men have dared to say of Him. I believe that we may find in the Bible the highest and purest religion ….. most of all in the history of Him in whose name we all are called. His religion — not the Christian religion, but the religion of Christ — the poor man's gospel; the message of forgiveness, of reconciliation, of love; and, oh, how gladly would I spend my life, in season and out of season, in preaching this! But I must have no hell terrors, none of these fear doctrines; they were not in the early creeds, God knows whether they were ever in the early gospels, or ever passed His lips. He went down to hell, but it was to break the chains, not to bind them.

James Anthony Froude (born 23 April 1818) English historian, novelist, and biographer

Death is not an event in life: we do not live to experience death.
If we take eternity to mean not infinite temporal duration but timelessness, then eternal life belongs to those who live in the present.
Our life has no end in just the way in which our visual field has no limits.

Ludwig Wittgenstein (born 26 April 1889) Austrian-born philosopher

He who hopes to grow in spirit
will have to transcend obedience and respect.
He'll hold to some laws
but he'll mostly violate
both law and custom, and go beyond
the established, inadequate norm.

Constantine P. Cavafy (born 29 April 1863) Greek poet

The advance of science is not comparable to the changes of a city, where old edifices are pitilessly torn down to give place to new, but to the continuous evolution of zoologic types which develop ceaselessly and end by becoming unrecognizable to the common sight, but where an expert eye finds always traces of the prior work of the centuries past.

Henri Poincaré (born 29 April 1854) One of France's greatest mathematicians and theoretical physicists

Zen is not a particular state but the normal state: silent, peaceful, unagitated. In Zazen neither intention, analysis, specific effort nor imagination take place. It's enough just to be without hypocrisy, dogmatism, arrogance — embracing all opposites.

Taisen Deshimaru (died 30 April 1982) Japanese Soto Zen Buddhist teacher
