Week 2026-07: On Harmony

"Having collected an army and concentrated his forces, he must blend and harmonize the different elements thereof before pitching his camp." (Sun Tzu, "The Art of War", 5th century BC)

"The peace of God is with them whose mind and soul are in harmony, who are free from desire and wrath, who know their own soul." (Bhagavad Gita)

"The soul that moves in the world of senses and yet keeps the senses in harmony ... finds rest in quietness." (Bhagavad Gita)

"There's no wisdom from a man without harmony, and without harmony there is no contemplation. Without contemplation there cannot be peace, and without peace there can be no joy..." (Bhagavad Gita) 

"If there is righteousness in the heart,
there will be beauty in the character.
If there is beauty in the character,
there will be harmony in the home.
If there is harmony in the home,
there will be order in the nation.
If there is order in the nation,
there will be peace in the world." (Confucius)

"Easy gives rise to difficult ... resonance

harmonizes sound, after follows before." (Lao Tzu)

"Figure out the rhythm of life and live in harmony with it." (Lao Tzu) 

"In the series of things those which follow are always aptly fitted to those which have gone before; for this series is not like a mere enumeration of disjointed things, which has only a necessary sequence, but it is a rational connection: and as all existing things are arranged together harmoniously, so the things which come into existence exhibit no mere succession, but a certain wonderful relationship." (Marcus Aurelius, "Meditations", cca. 180 AD)

“In the same way as regards the soul, when that kind of thing in us which mirrors the images of thought and intellect is undisturbed, we see them and know them in a way parallel to sense-perception, along with the prior knowledge that it is intellect and thought that are active. But when this is broken because the harmony of the body is upset, thought and intellect operate without an image, and then intellectual activity takes place without a mind-picture.” (Plotinus, “Enneads”, cca. 270 AD)

"There is timing in the whole life of the warrior, in his thriving and declining, in his harmony and discord. Similarly, there is timing in the Way of the merchant, in the rise and fall of capital. All things entail rising and falling timing. You must be able to discern this. In strategy there are various timing considerations. From the outset you must know the applicable timing and the inapplicable timing, and from among the large and small things and the fast and slow timings find the relevant timing, first seeing the distance timing and the background timing. This is the main thing in strategy. It is especially important to know the background timing, otherwise your strategy will become uncertain." (Miyamoto Musashi, "Go Rin No Sho" ["The Book of Five Rings"], 1645)

"Students should always be conscious to the advantages of fundamental principles, which are: practicing the movements slowly and evenly, inhaling and exhaling naturally so as to accumulate qi and concentrate the shen [spirit], and never employing muscular strength [li] too excessively. It is through softness and gentleness that you achieve mastery. This softness and gentleness means soft and continuous movements in conjunction with harmonious breathing." (Yearning K Chen, "T’ai Chi Ch’uan: Sword, Saber, Staff, and Dispersing-Hands Combined", 1943)

"Through slowness you can later be soft; through evenness you can later be gentle. The capability of being soft and gentle will cause the muscle and bone to be opened. The qi and blood will circulate harmoniously. From this the breath will become deep and long and the spirit of vitality can be stimulated and brought forth." (Yearning K Chen, "T’ai Chi Ch’uan: Sword, Saber, Staff, and Dispersing-Hands Combined", 1943)

"The very name Aikido indicates its dependence on the laws of nature, which we term ki. Aikido means the way to harmony with ki. That is to say, Aikido is a discipline to make the heart of nature our own heart, to understand love for all things, and to become one with nature. Techniques and physical strength have limits; the great way of the universe stretches to infinity." (Koichi Tohei, "Book of Ki: Co-ordinating Mind and Body in Daily Life", 1976)

"Simply stated, aikido is a budo open to all people who aspire to unify the ki of the universe with the ki of oneself. For all members of the human race, it is the path to attaining harmony with all beings. The gates of aikido are open to people of all ages, classes, sexes, nationalities and races. Non-discrimination and non-exclusiveness are basic characteristics of aikido." (Kisshomaru Ueshiba, "The Spirit of Aikido", 1981)

"The burning desire of the Founder in establishing aikido was to keep the most valuable legacy of budo alive in the modern world. In order to accomplish his goal he went beyond differences in outward form to grasp the essence of each martial art and to bring it to life in a new form. The motivating force was his intense spiritual quest to discover a life-giving and life-affirming philosophy in budo. The result was the transformation of the heart of budo into the heart of aikido, the way of harmony and love."  (Kisshomaru Ueshiba, "The Spirit of Aikido", 1981)

"The subtle working of ki is the maternal source that affects changes in breath. It is also the source of martial art as love. When one unifies mind and body by virtue of ki and manifests ai-ki (harmony of ki), delicate changes in breath-power occur spontaneously and 'waza' (proper technique) flows freely." (Kisshomaru Ueshiba, "The Spirit of Aikido", 1981)

"The burning desire of the Founder in establishing aikido was to keep the most valuable legacy of budo alive in the modern world. In order to accomplish his goal he went beyond differences in outward form to grasp the essence of each martial art and to bring it to life in a new form. The motivating force was his intense spiritual quest to discover a life-giving and life-affirming philosophy in budo. The result was the transformation of the heart of budo into the heart of aikido, the way of harmony and love."  (Kisshomaru Ueshiba, "The Spirit of Aikido", 1981)

"The real Art of Peace is not to sacrifice a single one of your warriors to defeat an enemy. Vanquish your foes by always keeping yourself in a safe and unassailable position; then no one will suffer any losses. The Way of a Warrior, the Art of Politics, is to stop trouble before it starts. It consists in defeating your adversaries spiritually by making them realize the folly of their actions. The Way of a Warrior is to establish harmony." (Morihei Ueshiba, "The Art of Peace", 1992)

"But you cannot have harmony without a commitment to ethical behavior. It's the fence that keeps out the goats that will eat all the young shoots in your garden." (Jon Kabat-Zinn, "Wherever You Go, There You Are: Mindfulness meditation for everyday life", 1994)

"No price is too great to pay for inner peace. Peace is the harmonious control of life. It is vibrant with life-energy. It is a power that easily transcends all our worldly knowledge. Yet it is not separate from our earthly existence. If we open the right avenues within, this peace can be felt here and now." (Sri Chinmoy Kumar Ghose, "The Jewels of Happiness: Inspiration and Wisdom to Guide Your Life-Journey", 2015)

"Always aim at complete harmony of thought and word and deed. Always aim at purifying your thoughts and everything will be well." (Gandhi)

"Happiness is not a matter of intensity but of balance and order and rhythm and harmony." (Thomas Merton)

"Harmonizing opposites by going back to their source is the distinctive quality of the Zen attitude, the Middle Way: embracing contradictions, making a synthesis of them, achieving balance." (Taisen Deshimaru)

"It is in virtue that happiness consists, for virtue is the state of mind which tends to make the whole of life harmonious." (Zeno)

"Meditation is, first of all, a tool for surveying our territory so we can know what is going on. With the energy of mindfulness, we can calm things down, understand them, and bring harmony back to the conflicting elements inside us." (Thich Nhat Hanh)

"It is a grave mistake to think that budo is about being stronger than your partner or opponent and that you have to defeat him. In true budo, there is no partner. Th ere is no enemy. True budo is to become one with the universe. It is to be united with the universe’s center. In aikido, we do not train to become strong or to defeat opponents, but to make even a small contribution to peace for all people in the world. To that purpose we must strive to harmonize with the center of the universe."  (Morihei Ueshiba)

"Opposition brings concord. Out of discord comes the fairest harmony." (Heraclitus of Ephesus)

"Out of chaos, find simplicity, From discord, find harmony." (Bruce Lee)

"The Great Harmony is called the Way (Tao, Moral Law). It embraces the nature which underlies all counter processes of floating and sinking, rising and falling, and motion and rest. It is the origin of the process of fusion and intermingling, of overcoming and being overcome, and of expansion and contraction. At the commencement, these processes are incipient, subtle, obscure, easy, and simple, but at the end they are extensive, great, strong, and firm. It is ch'ien (Heaven) that begins with the knowledge of Change, and k'un (Earth) that models after simplicity. That which is dispersed, differentiated, and capable of assuming form becomes material force (ch'i), and that which is pure, penetrating, and capable of assuming form becomes spirit. Unless the whole universe is in the process of fusion and intermingling like fleeting forces moving in all directions, it may not be called Great Harmony." (Chang Tsai)

"The highest education is that which does not merely give us information but makes our life in harmony with all existence." (Rabindranath Tagore)

"There is harmony in our activity, and where there is harmony there is calmness." (Daisetzu T Suzuki)

"Through our eyes, the universe is perceiving itself. Through our ears, the universe is listening to its harmonies. We are the witnesses through which the universe becomes conscious of its glory, of its magnificence." (Alan Watts)

"To define Buddhism without a lot of words and phrases, we can simply say, 'Don't cling or hold on to anything. Harmonize with actuality, with things as they are.'" (Ajahn Chah)

"When we in prayer seek only the glorification of the name of God, then we are in complete harmony with the spirit of prayer. Then our hearts are at rest both while we pray and after we have prayed. Then we can wait for the Lord." (Ole Hallesby)

"When we succeed in truly thanking God, we feel good at heart. The reason is that we have been created to give glory to God, now and forever-more. And every time we do so, we feel that we are in harmony with His plans and purposes for our lives. Then we are truly in our element. That is why it is so blessed." (Ole Hallesby)

"Wandering re-establishes the original harmony which once existed between man and the universe." (Anatole France)

"When you walking along naturally, you're walking in the harmony of the Unborn." (Bankei Yōtaku)

Week 2026-06: On Growth

"He that would make a real progress in knowledge must dedicate his age as well as first fruits - the latter growth as well as the first-fruits - at the altar of truth." (Bishop George Berkeley, "Siris", 1744)

"Growth is limited by that necessity which is present in the least amount. And, naturally, the least favorable condition controls the growth rate." (Frank Herbert, "Dune", 1965)

"Pouncing on an idea as soon as it appears kills the idea. Too early and too enthusiastic logical attention either freezes the idea or forces it into the old moulds. Concentration on an idea isolates it from its surroundings and arrests its growth. The glare of attention inhibits the fertile semi-conscious processes that go to develop an idea." (Edward de Bono, "New Think: The Use of Lateral Thinking in the Generation of New Ideas", 1967)

 "It's the sides of the mountain which sustain life, not the top. Here's where things grow." (Robert Pirsig, "Zen and the Art of Motorcycle Maintenance", 1974)

"Magic is hidden in the language we speak. The webs that you can tie and untie are at your command if only you pay attention to what you already have (language) and the structure of the incantations for growth." (Richard Bandler & John Grinder, "The Structure of Magic", 1975)

"The most pervasive paradox of the human condition which we see is that the processes which allow us to survive, grow, change, and experience joy are the same processes which allow us to maintain an impoverished model of the world - our ability to manipulate symbols, that is, to create models. So the processes which allow us to accomplish the most extraordinary and unique human activities are the same processes which block our further growth if we commit the error of mistaking the model of the world for reality." (Richard Bandler & John Grinder, "The Structure of Magic", 1975)

"Each day of human life contains joy and anger, pain and pleasure, darkness and light, growth and decay. Each moment is etched with nature's grand design - do not try to deny or oppose the cosmic order of things." (Morihei Ueshiba, "The Art of Peace", 1991)

"We live on an island surrounded by a sea of ignorance. As our island of knowledge grows, so does the shore of our ignorance." (John A Wheeler, Scientific American Vol. 267, 1992)

"[...] all problems can be reperceived as challenges, or 'opportunities' to change, grow or learn." (Robert B Dilts, "Sleight of Mouth: The Magic of Conversational Belief Change", 1999)

"Change is the end result of all true learning. Change involves three things: First, a dissatisfaction with self - a felt void or need; second, a decision to change to fill the void or need; and third, a conscious dedication to the process of growth and change - the willful act of making the change, doing something." (Leo Buscaglia)

"Chaos in the world brings uneasiness, but it also allows the opportunity for creativity and growth." (Tom Barrett)

"Don't get set into one form, adapt it and build your own, and let it grow, be like water." (Bruce Lee)

"Everyone wants to live on top of the mountain, but all the happiness and growth occurs while you’re climbing it." (Andy Rooney)

"Fundamentally mindfulness is a simple concept. Its power lies in its practice and its applications. Mindfulness means paying attention in a particular way: on purpose, in the present moment, and non-judgmentally. This kind of attention nurtures greater awareness, clarity, and acceptance of present-moment reality. It wakes us up to the fact that our lives unfold only in moments. If we are not fully present for many of those moments, we may not only miss what is most valuable in our lives but also fail to realize the richness and the depth of our possibilities for growth, and transformation." (Jon Kabat-Zinn)

"Happiness is having a sense of self, not a feeling of being perfect, but of being good enough and knowing that you are in the process of growth, of being, of achieving levels of joy. It’s a wonderful contentment and acceptance of who and what you are and a knowledge that the world and life are full of wondrous adventures and possibilities." (Leo Buscaglia)

"If you were all alone in the universe with no one to talk to, no one with which to share the beauty of the stars, to laugh with, to touch, what would be your purpose in life? It is other life; it is love, which gives your life meaning. This is harmony. We must discover the joy of each other, the joy of challenge, the joy of growth." (Mitsugi Saotome)

"Life is growth, and the more we travel, the more truth we can understand. Understanding the things that surround us is the best preparation to understand the things that lie beyond." (Hypatia of Alexandria)

"Spring comes, and the grass grows by itself." (Lao Tzu)

"Styles tend to not only separate men - because they have their own doctrines and then the doctrine became the gospel truth that you cannot change. But if you do not have a style, if you just say: Well, here I am as a human being, how can I express myself totally and completely? Now, that way you won't create a style, because style is a crystallization. That way, it's a process of continuing growth." (Bruce Lee)

"Suffering is a challenge; when you suffer you are challenged, when there is a problem you are challenged. When you encounter the problem, only then do you grow. More insecurity, more growth; more security, less growth. If everything is secure around you, you are already in your grave, you are no longer alive. Life exists in danger, life always exists in the possibility of going astray. But one who goes astray can come back, one who fails can succeed." (Osho)

"The growth of wisdom may be gauged exactly by the diminution of ill temper." (Friedrich Nietzsche)

"The quality of your growth is a direct reflection of how much discomfort you can comfortably live with" (Anthony Robbins)

"There is a birth and growth of the self. According to his action', the embodied being assumes forms successively in many places; many forms gross and subtle he assumes by force of his own qualities of nature..." (Swetaswatara Upanishad)

"The mind is like a fertile garden. It will grow anything you wish to plant - beautiful flowers or weeds. And so it is with successful, healthy thoughts or with negative ones that will, like weeds, strangle and crowd the others. Do not allow negative thoughts to enter your mind for they are the weeds that strangle confidence." (Bruce Lee)

"Wasting energy to obtain rare objects only impedes one's growth." (Lao Tzu)

"You have to start where people are, because their growth is going to be from there, not from some abstraction or where you are or someone else is." (Myles Horton)

Week 2026-05: On Energy

"By standing alone and unchanging, you will find that everything comes to you and the energy of the cosmos will never be exhausted." (Lao Tsu)

"Wasting energy to obtain rare objects only impedes one's growth." (Lao Tzu)

"For truth is simple and without fuss, whereas error affords opportunity for dissipating time and energy." (Johann Wolfgang von Goethe, 1829)

"Meditation is the most effective form of relaxation. It not only relaxes the body and mind but also feeds them with vital energy, peace and happiness." (Maharishi Mahesh Yogi, "Meditation: Easy system propounded by Maharishi Mahesh Yogi", 1962)

"The heart is the sovereign of the five organs, tea is the chief of the bitter foods, and bitter is the chief of the tastes. For this reason the heart loves bitter things, and when it is doing well all the other organs are properly regulated. [...] When, however, the whole body feels weak, devitalized, and depressed, it is a sign that the heart is ailing. Drink lots of tea, and one 's energy and spirits ww be restored to full strength." (Myōan Eisai, "Drink Tea and Prolong Life", cca 12th century)

"Just concentrate your whole energy into this Mu, and do not allow any discontinuation. When you enter this Mu and there is no discontinuation, your attainment will be as a candle burning and illuminating the whole universe." (Ekai, "The Gateless Gate", cca. 13the century)

"When brute-force is too strong, it cannot exist for long; and likewise intrinsic energy cannot be totally devoid of strength either." (Yearning K Chen, "T’ai Chi Ch’uan: Sword, Saber, Staff, and Dispersing-Hands Combined", 1943)

"Compassion automatically invites you to relate with people because you no longer regard people as a drain on your energy." (Chögyam Trungpa, "Cutting Through Spiritual Materialism", 1973)

"When the conscious mind expands to embrace deeper levels of thinking, the thought wave becomes more powerful and results in added energy and intelligence." (Maharishi Mahesh Yogi, "Thirty Years Around the World: 1957-1964", 1986)

"Meditation is silence, energising and fulfilling. Silent is the eloquent expression of the inexpressible." (Sri Chinmoy Kumar Ghose, "The Silent Teaching: A Beginner's Guide to Meditation", 1996)

"Train not by thought, but by practice. Learn a wide variety of arts and skills, and do not fix on only one. Know not only your own techniques but also those of many others. Find out rationally what is an advantage and what is a disadvantage. Foster an intuitive ability to judge all things. Feel an essence that you cannot see on the surface. Pay attention to the very smallest of phenomena. (Everything takes its own course, and sometimes we get unexpected results.) Do nothing in vain, for the energy and time we have is limited." (Kazumi Tabata, "Secret Tactics: Lessons From the Great Masters of Martial Arts", 2003)

"Intention is not something you do, but rather a force that exists in the universe as an invisible field of energy, a power that can carry us. (Wayne Dyer, "The Power of Intention", 2004)

"Thoughts are mental energy; they're the currency that you have to attract what you desire. You must learn to stop spending that currency on thoughts you don't want." (Wayne Dyer, "Being in Balance: 9 Principles for Creating Habits to Match Your Desires", 2006)

"Every conscious thought you have, every moment you spend on an idea, is a commitment to be stuck with that idea and with aspects of that level of thinking, for the rest of your life. Spending just 10 seconds focusing on a topic that does not serve your interests is to invest your energy along a path that will continue to draw from you and define you." (Kevin Michel, "Moving Through Parallel Worlds to Achieve Your Dreams", 2013)

"Small shifts in your thinking, and small changes in your energy, can lead to massive alterations of your end result." (Kevin Michel, "Moving Through Parallel Worlds to Achieve Your Dreams", 2013)

"No price is too great to pay for inner peace. Peace is the harmonious control of life. It is vibrant with life-energy. It is a power that easily transcends all our worldly knowledge. Yet it is not separate from our earthly existence. If we open the right avenues within, this peace can be felt here and now." (Sri Chinmoy Kumar Ghose, "The Jewels of Happiness: Inspiration and Wisdom to Guide Your Life-Journey", 2015)

"A good martial artist puts his mind on one thing at a time. He takes each thing as it comes, finishes with it, and passes on to the next. Like a Zen master, he is not concerned with the past or the future, only with what he is doing at that moment. Because his mind is tight, he is calm and able to maintain strength in reserve. And then there will be room for only one thought, which will fill his entire being as water fills a pitcher. You wasted an enormous amount of energy because you did not localize and focus your mind. Always remember: in life as well as on the mat an unfocused or 'loose' mind wastes energy." (Bruce Lee)

"Acceptance looks like a passive state, but in reality it brings something entirely new into this world. That peace, a subtle energy vibration, is consciousness." (Eckhart Tolle)

"Be vigorous and full of energy, and make ceaseless efforts. This means that little things do not discourage you and that you approach all things boldly and with an attitude of determination." (Koichi Tohei)

"Budo is not about destroying other human beings with one’s strength or weapons, or annihilating the world by force of arms. True budo is channeling the universal energy (ki) to protect world peace, to engender all things fittingly, nurture them and save them from harm." (Morihei Ueshiba) 

"Beginners should by all means strive for Truth. You must not force yourself to train or do zazen too vigorously before you realize the Truth. If you forcefully let out energy and practice Zen in violent ways, you will become fatigued, lose your energy, and it will all be of no use." (Suzuki Shosan)

"Evil passions, earthly desires, carnal lust, taken all together, are due to two conditions: low vital energy and scattered wits." (Toin)

"If you know how to practice mindfulness you can generate peace and joy right here, right now. And you'll appreciate that and it will change you. In the beginning, you believe that if you cannot become number one, you cannot be happy, but if you practice mindfulness you will readily release that kind of idea. We need not fear that mindfulness might become only a means and not an end because in mindfulness the means and the end are the same thing. There is no way to happiness; happiness is the way." (Thich Nhat Hanh)

"Meditation is, first of all, a tool for surveying our territory so we can know what is going on. With the energy of mindfulness, we can calm things down, understand them, and bring harmony back to the conflicting elements inside us." (Thich Nhat Hanh) 

"Judo helps us to understand that worry is a waste of energy." (Jigoro Kano)

"Just stop your wandering, look penetratingly into your inherent nature, and,
concentrating your spiritual energy, sit in zazen and break through." (Bassui Tokusho)

"On a deeper level you are already complete. When you realize that, there is a joyous energy behind what you do." (Eckhart Tolle)

"Since you cannot do real zazen no matter how much I teach you, I think I’ll show you from now on how to use the vigorous energy you have when you are angry." (Suzuki Shosan)

"The first miracle brought about by mindfulness is your own presence, your real presence. With this energy dwelling in you, you become completely alive. When the energy of mindfulness is dwelling in you, Buddha is dwelling in you. The energy of mindfulness is the energy of Buddha. It is the equivalent of the Holy Spirit. Where the Holy Spirit is, there is also understanding, life, healing, and compassion."  (Thich Nhat Hanh)

"The lamps are different, but the Light is the same. One matter, one energy, one Light, one Light-mind, endlessly emanating all things." (Rumi) 

"The modern West, after the enlightenment, became the first major civilization in the history of humanity to deny almost entirely the existence of the Great Nest (or chain) of Being. In its place was a 'flatland' conception of the universe as composed basically of matter (or matter/energy) and this material universe [...] could be studied by science and science alone." (Ken Wilber)

"The universe is a fractal. Whatever energy signature we carry will be repeated infinitely, again and again...until we change that vibration." (Paige Bartholomew)

"There are many aspects to success; material wealth is only one component. But success also includes good health, energy and enthusiasm for life, fulfilling relationships, creative freedom, emotional and psychological stability, a sense of well-being, and peace of mind." (Deepak Chopra)

"There are many ways to calm a negative energy without suppressing or fighting it. You recognize it, you smile to it, and you invite something nicer to come up and replace it; you read some inspiring words, you listen to a piece of beautiful music, you go somewhere in nature, or you do some walking meditation." (Thich Nhat Hanh)

"There is in the body a current of energy, affection and intelligence, which guides, maintains and energizes the body. Discover that current, and hold onto it unswervingly. Be aware of the spark of life that weaves the tissues of your body and stay with it. It is the only reality that the body has. It is like looking at a burning incense stick; you see the stick and the smoke first; when you notice the fiery point, you realize it has the power to consume mountains of sticks and fill the universe with smoke. Timelessly the Self actualizes itself, without exhausting its infinite possibilities. In the incense stick simile, the stick is the body, and the smoke is the mind. As long as the mind is busy with its contortions, it does not perceive its source. The Guru comes and turns your attention to the spark within."  (Sri Nisargadatta Maharaj)

"Whenever an answer, a solution, or a creative idea is needed, stop thinking for a moment by focusing attention on your inner energy field. [...] When you resume thinking, it will be fresh and creative." (Eckhart Tolle)

"You must learn to allow patience and stillness to take over from anxiety and frantic activity for the sake of doing something, Between martial artists of the first rank, there is room for only one mistake. Before an exchange of blows, several minutes may be spent in controlled patience and planning while each man respectfully observes his opponent, studying his position or stance, watching, getting ideas, and charging his energy. When one man thinks he is going to attack, his opponent may quickly change his stance. If he has overreacted, his opponent makes a note of it. This is a weakness which he will later attempt to use to his advantage." (Jim Lau)

"You seem to practice 'Empty Shell Zazen' and think that not thinking of anything is 'no-thought, no-mind'. You even start to feel good sitting vacantly. But if you do that kind of zazen you’ll lose your vigorous energy and become sick or go crazy. True 'no-thought, no-mind' zazen is just one thing - to have a dauntless mind." (Suzuki Shosan)

Week 2026-03: On Probability

"That is probable which for the most part usually comes to pass, or which is a part of the ordinary beliefs of mankind, or which contains in itself some resemblance to these qualities, whether such resemblance be true or false." (Marcus T Cicero, "De Inventione", cca. 86–84 BC)

"Take away probability, and you can no longer please the world; give probability, and you can no longer displease it." (Blaise Pascal, "Thoughts", 1670)

"Ignorance gives one a large range of probabilities." (George Eliot, "Daniel Deronda", 1876)

"When you have eliminated all which is impossible, then whatever remains, however improbable, must be the truth." (Arthur C Doyle, "The Sign of Four", 1890

"Every probability - and most of our common, working beliefs are probabilities - is provided with buffers at both ends, which break the force of opposite opinions clashing against it […]" (Oliver W Holmes, "The Autocrat of the Breakfast-Table", 1891) 

"It is more than possible; it is probable." (Arthur C Doyle, "The Memoirs of Sherlock Holmes", 1893)

"If everything, everything were known, statistical estimates would be unnecessary. The science of probability gives mathematical expression to our ignorance, not to our wisdom." (Samuel R Delany, "Time Considered as a Helix of Semi-Precious Stones", 1969)

"People are entirely too disbelieving of coincidence. They are far too ready to dismiss it and to build arcane structures of extremely rickety substance in order to avoid it. I, on the other hand, see coincidence everywhere as an inevitable consequence of the laws of probability, according to which having no unusual coincidence is far more unusual than any coincidence could possibly be." (Isaac Asimov, "The Planet That Wasn't", 1976)

"In the real world irrational things happened, impossible coincidences happened, because probability required that coincidences rarely, but not never, occur." (Orson Scott Card, "Ender’s Game", 1985)

"One of the elementary rules of nature is that, in the absence of a law prohibiting an event or phenomenon, it is bound to occur with some degree of probability. To put it simply and crudely: Anything that can happen does happen." (Kenneth W Ford)
