When an angel by divine command
With rising tempests shakes a guilty land,
Such as of late o'er pale Britannia passed,
Calm and serene he drives the furious blast;
And, pleas'd th' Almighty's orders to perform,
Rides in the whirlwind, and directs the storm.

Joseph Addison (born 1 May 1672) English politician and writer

Before abstraction everything is one, but one like chaos; after abstraction everything is united again, but this union is a free binding of autonomous, self-determined beings. Out of a mob a society has developed, chaos has been transformed into a manifold world.

Novalis (born 2 May 1772) German author, philosopher and poet

No enterprise is more likely to succeed than one concealed from the enemy until it is ripe for execution.
Nothing is of greater importance in time of war than in knowing how to make the best use of a fair opportunity when it is offered.

Niccolò Machiavelli (born 3 May 1469) Florentine political philosopher, historian, musician, poet, and playwright

Beneficence is godlike, and he who does most good to his fellow-man is the Master of Masters, and has learned the Art of Arts. Enrich and embellish the universe as you will, it is only a fit temple for the heart that loves truth with a supreme love. Inanimate vastness excites wonder; knowledge kindles admiration, but love enraptures the soul. Scientific truth is marvellous, but moral truth is divine; and whoever breathes its air and walks by its light, has found the lost paradise. For him, a new heaven and a new earth have already been created. His home is the sanctuary of God, the Holy of Holies.

Horace Mann (born 4 May 1796) American education reformer and abolitionist

Is it an excellence in your love that it can love only the extraordinary, the rare? If it were love’s merit to love the extraordinary, then God would be — if I dare say so — perplexed, for to Him the extraordinary does not exist at all. The merit of being able to love only the extraordinary is therefore more like an accusation, not against the extraordinary nor against love, but against the love which can love only the extraordinary. Perfection in the object is not perfection in the love. Erotic love is determined by the object; friendship is determined by the object; only love of one’s neighbour is determined by love. Therefore genuine love is recognizable by this, that its object is without any of the more definite qualifications of difference, which means that this love is recognizable only by love.

Søren Kierkegaard (born 5 May 1813) Danish philosopher and theologian

Do not interrupt the flight of your soul; do not distress what is best in you; do not enfeeble your spirit with half wishes and half thoughts. Ask yourself and keep on asking until you find the answer, for one may have known something many times, acknowledged it; one may have willed something many times, attempted it — and yet, only the deep inner motion, only the heart's indescribable emotion, only that will convince you that what you have acknowledged belongs to you, that no power can take it from you — for only the truth that builds up is truth for you.

Søren Kierkegaard in "Either/Or" (born 5 May 1813) Danish philosopher and theologian

The voice of the intellect is a soft one, but it does not rest until it has gained a hearing. Ultimately, after endlessly repeated rebuffs, it succeeds. This is one of the few points in which it may be optimistic about the future of mankind, but in itself it signifies not a little.

Sigmund Freud (born 6 May 1856) Austrian neurologist and psychologist

The very essence of democracy is the absolute faith that while people must cooperate, the first function of democracy, its peculiar gift, is to develop each individual into everything that he might be. But I submit to you that when in each man the dream of personal greatness dies, democracy loses the real source of its future strength.

Edwin H. Land (born 7 May 1909) American scientist and inventor

If nature has been frugal in her gifts and endowments, there is the more need of art to supply her defects. If she has been generous and liberal, know that she still expects industry and application on our part, and revenges herself in proportion to our negligent ingratitude. The richest genius, like the most fertile soil, when uncultivated, shoots up into the rankest weeds; and instead of vines and olives for the pleasure and use of man, produces, to its slothful owner, the most abundant crop of poisons.

David Hume (born 7 May 1711) Scottish philosopher, historian, economist and essayist

Poets say science takes away from the beauty of the stars — mere globs of gas atoms. Nothing is "mere". I too can see the stars on a desert night, and feel them. But do I see less or more? The vastness of the heavens stretches my imagination — stuck on this carousel my little eye can catch one-million-year-old light. A vast pattern — of which I am a part… What is the pattern or the meaning or the why? It does not do harm to the mystery to know a little more about it.

Richard Feynman (born 11 May 1918) American physicist

Happy the man, and happy he alone,
He who can call today his own;
He who, secure within, can say,
Tomorrow, do thy worst, for I have lived today.
Be fair, or foul, or rain, or shine,
The joys I have possessed, in spite of fate, are mine.
Not heaven itself upon the past has power;
But what has been, has been, and I have had my hour.

John Dryden, based on "Ode XXIX" of HoraceEnglish poet, literary critic, and playwright

Not living in fear is a great gift, because certainly these days we do it so much. And do you know what I like about comedy? You can’t laugh and be afraid at the same time — of anything. If you're laughing, I defy you to be afraid.

Stephen Colbert (born 13 May 1964) American satirist, comedian, writer and actor

Union and co-operation in war obviously increase the power of the individual a thousand fold. Is there the shadow of a reason why they should not produce equal effects in peace; why the principle of co-operation should not give to men the same superior powers, and advantages, (and much greater) in the creation, preservation, distribution and enjoyment of wealth?

Robert Owen (born 14 May 1771) Welsh socialist and social reformer

Errors now almost universally exist, and must be overcome solely by the force of reason; and as reason, to effect the most beneficial purposes, makes her advance by slow degrees, and progressively substantiates one truth of high import after another, it will be evident, to minds of comprehensive and accurate thought, that by these and similar compromises alone can success be rationally expected in practice. For such compromises bring truth and error before the public; and whenever they are fairly exhibited together, truth must ultimately prevail.

Robert Owen (born 14 May 1771) Welsh socialist and social reformer

The slave system is one of constant danger, distrust, suspicion, and watchfulness. It debases those whose toil alone can produce wealth and resources for defence, to the lowest degree of which human nature is capable, to guard against mutiny and insurrection, and thus wastes energies which otherwise might be employed in national development and aggrandizement. The free-labor system educates all alike, and by opening all the fields of industrial employment and all the departments of authority, to the unchecked and equal rivalry of all classes of men, at once secures universal contentment, and brings into the highest possible activity all the physical, moral, and social energies of the whole state.

William H. Seward (born 16 May 1801) American politician, 12th Governor of New York and United States Senator

I believe, in spite of all, in truth's victory. I believe in the momentous value, hereafter inviolable, of those few truly fraternal men in all the countries of the world, who, in the oscillation of national egoisms let loose, stand up and stand out, steadfast as the glorious statues of Right and Duty.

Henri Barbusse (born 17 May 1873) French novelist, journalist and communist

There are cloudy moments when one asks himself if men do not deserve all the disasters into which they rush! No — I recover myself — they do not deserve them. But we, instead of saying "I wish" must say "I will." And what we will, we must will to build it, with order, with method, beginning at the beginning, when once we have been as far as that beginning. We must not only open our eyes, but our arms, our wings.

Henri Barbusse (born 17 May 1873) French novelist, journalist and communist

The impartiality which, in contemplation, is the unalloyed desire for truth, is the very same quality of mind which, in action, is justice, and in emotion is that universal love which can be given to all, and not only to those who are judged useful or admirable. Thus contemplation not only enlarges the objects of our thoughts, but also the objects of our actions and our affections: it makes us citizens of the universe, not only of one walled city at war with the rest. In this citizenship of the universe consists man's true freedom, and his liberation from the thralldom of narrow hopes and fears.

Bertrand Russell (born 18 May 1872) British philosopher, logician, mathematician and historian

Mankind is a single body and each nation a part of that body. We must never say "What does it matter to me if some part of the world is ailing?" If there is such an illness, we must concern ourselves with it as though we were having that illness.

Mustafa Kemal AtatürkTurkish army officer and revolutionist statesman

I wish to live because life has within it that which is good, that which is beautiful and that which is love. Therefore, since I have known all of these things, I have found them to be reason enough and — I wish to live. Moreover, because this is so, I wish others to live for generations and generations and generations.

Lorraine Hansberry (born 19 May 1930) American playwright

The peculiar evil of silencing the expression of an opinion is, that it is robbing the human race; posterity as well as the existing generation; those who dissent from the opinion, still more than those who hold it. If the opinion is right, they are deprived of the opportunity of exchanging error for truth: if wrong, they lose, what is almost as great a benefit, the clearer perception and livelier impression of truth, produced by its collision with error.

John Stuart Mill (born 20 May 1806) English political philosopher and economist

The only purpose for which power can be rightfully exercised over any member of a civilized community, against his will, is to prevent harm to others. His own good, either physical or moral, is not a sufficient warrant. He cannot rightfully be compelled to do or forbear because it will be better for him to do so, because it will make him happier, because, in the opinions of others, to do so would be wise, or even right. These are good reasons for remonstrating with him, or reasoning with him, or persuading him or entreating him, but not for compelling him, or visiting him with any evil, in case he do otherwise.

John Stuart Mill (born 20 May 1806) English political philosopher and economist

Some Figures monstrous and mis-shap'd appear,
Consider'd singly, or beheld too near,
Which, but proportion'd to their Light, or Place,
Due Distance reconciles to Form and Grace.
A prudent Chief not always must display
His Pow'rs in equal Ranks, and fair Array,
But with th' Occasion and the Place comply,
Conceal his Force, nay seem sometimes to Fly.
Those oft are Stratagems which Errors seem,
Nor is it Homer Nods, but We that Dream.

Alexander Pope in "An Essay on Criticism" (born 21 May 1688) English poet

The flying Rumours gather'd as they roll'd,
Scarce any Tale was sooner heard than told;
And all who told it, added something new,
And all who heard it, made Enlargements too,
In ev'ry Ear it spread, on ev'ry Tongue it grew.

Alexander Pope (born 21 May 1688) English poet

Life is infinitely stranger than anything which the mind of man could invent. We would not dare to conceive the things which are really mere commonplaces of existence. If we could fly out of that window hand in hand, hover over this great city, gently remove the roofs, and peep in at the queer things which are going on, the strange coincidences, the plannings, the cross-purposes, the wonderful chains of events, working through generations, and leading to the most outre results, it would make all fiction with its conventionalities and foreseen conclusions most stale and unprofitable.

Arthur Conan Doyle in "A Case of Identity" (born 22 May 1859) British writer, creator of "Sherlock Holmes"

The more we progress the more we tend to progress. We advance not in arithmetical but in geometrical progression. We draw compound interest on the whole capital of knowledge and virtue which has been accumulated since the dawning of time.

Arthur Conan Doyle (born 22 May 1859) British writer, creator of "Sherlock Holmes"

Let no one dare to call another mad who is not himself willing to rank in the same class for every perversion and fault of judgment. Let no one dare aid in punishing another as criminal who is not willing to suffer the penalty due to his own offenses.

Margaret Fuller (born 23 May 1810) American author, journalist, critic and women's rights activist

How many roads must a man walk down
Before you call him a man?
Yes, 'n' how many seas must a white dove sail
Before she sleeps in the sand?
Yes, 'n' how many times must the cannon balls fly
Before they're forever banned?
The answer, my friend, is blowin' in the wind,
The answer is blowin' in the wind.

Bob Dylan (born 24 May 1941) American singer-songwriter

How many times must a man look up
Before he can see the sky?
Yes, 'n' how many ears must one man have
Before he can hear people cry?
Yes, 'n' how many deaths will it take till he knows
That too many people have died?
The answer, my friend, is blowin' in the wind,
The answer is blowin' in the wind.

Bob Dylan (born 24 May 1941) American singer-songwriter

You will hear every day the maxims of a low prudence. You will hear, that the first duty is to get land and money, place and name. "What is this Truth you seek? What is this Beauty?" men will ask, with derision. If, nevertheless, God have called any of you to explore truth and beauty, be bold, be firm, be true. When you shall say, "As others do, so will I. I renounce, I am sorry for it, my early visions; I must eat the good of the land, and let learning and romantic expectations go, until a more convenient season." — then dies the man in you; then once more perish the buds of art, and poetry, and science, as they have died already in a thousand thousand men. The hour of that choice is the crisis of your history; and see that you hold yourself fast by the intellect. … Bend to the persuasion which is flowing to you from every object in Nature, to be its tongue to the heart of man, and to show the besotted world how passing fair is wisdom.

Ralph Waldo Emerson (born 25 May 1803) American lecturer, essayist and poet

Be an artist superior to tricks of art. Show frankly, as a saint would do, all your experience, your methods, tools, and means. Welcome all comers to the freest use of the same. And out of this superior frankness and charity, you shall learn higher secrets of your nature, which gods will bend and aid you to communicate.

Ralph Waldo Emerson (born 25 May 1803) American lecturer, essayist and poet

The more clearly we can focus our attention on the wonders and realities of the universe about us the less taste we shall have for the destruction of our race. Wonder and humility are wholesome emotions, and they do not exist side by side with a lust for destruction.

Rachel Carson (born 27 May 1907) American biologist and writer

Like the wind crying endlessly through the universe, Time carries away the names and the deeds of conquerors and commoners alike. And all that we are, all that remains, is in the memories of those who cared we came this way for a brief moment.

Harlan Ellison (born 27 May 1934) American writer of speculative fiction

In my books I have lifted bits from various religions in trying to come to a better understanding; I've made use of religious themes and symbols. Now, as the world becomes more pagan, one has to lead people in the same direction in a different way…

Patrick White (born 28 May 1912) Australian novelist and winner of the 1973 Nobel Prize for Literature

War of any kind is abhorrent. Remember that since the end of World War II, over 40 million people have been killed by conventional weapons. So, if we should succeed in averting nuclear war, we must not let ourselves be sold the alternative of conventional weapons for killing our fellow men. We must cure ourselves of the habit of war.

Patrick White (born 28 May 1912) Australian novelist and winner of the 1973 Nobel Prize for Literature

The most unfathomable schools and sages have never attained to the gravity which dwells in the eyes of a baby of three months old. It is the gravity of astonishment at the universe, and astonishment at the universe is not mysticism, but a transcendent common-sense. The fascination of children lies in this: that with each of them all things are remade, and the universe is put again upon its trial.

G. K. Chesterton (born 29 May 1874) British writer, critic and author

Talk not so much … of the great old masters, who but painted and chisell’d. Study not only their productions. There is a still higher school for him who would kindle his fire with coal from the altar of the loftiest and purest art. It is the school of all grand actions and grand virtues, of heroism, of the death of patriots and martyrs — of all the mighty deeds written in the pages of history — deeds of daring, and enthusiasm, devotion, and fortitude.

Walt Whitman (born 31 May 1819) American poet, essayist and journalist

Be composed — be at ease with me — I am Walt Whitman, liberal and lusty as Nature,
Not till the sun excludes you do I exclude you,
Not till the waters refuse to glisten for you and the leaves to rustle for you, do my words refuse to glisten and rustle for you.

Walt Whitman in Leaves of Grass (born 31 May 1819) American poet, essayist and journalist
