To me, the rainbow was a profoundly hopeful symbol, separating the the white light of appearances into its multiple spectrum and revealing a hidden dimension. It reminded me of my belief that it was the mission of science to pierce through the layers of everyday reality and penetrate to the truth.

[To] mechanical progress there is apparently no end: for as in the past so in the future, each step in any direction will remove limits and bring in past barriers which have till then blocked the way in other directions; and so what for the time may appear to be a visible or practical limit will turn out to be but a bend in the road. (Opening address to the Mechanical Science Section, Meeting of the British Association, Manchester.)

To me it seems that those sciences are vain and full of error which are not born of experience, mother of all certainty, first-hand experience which in its origins, or means, or end has passed through one of the five senses. And if we doubt the certainty of everything which passes through the senses, how much more ought we to doubt things contrary to these senses – ribelli ad essi sensi – such as the existence of God or of the soul or similar things over which there is always dispute and contention. And in fact it happens that whenever reason is wanting men to cry out against one another, which does not happen with certainties. For this reason we shall say that where the cry of controversy is heard, there is no true science, because the truth has one single end and when this is published, argument is destroyed for ever.

To many intellectuals such as Celsus, the whole idea of a ‘Creation myth’ was not only implausible but redundant. During this period in Rome, a popular and influential philosophical theory offered an alternative view. This theory – an Epicurean one – stated that everything in the world was made not by any divine being but by the collision and combination of atoms. According to this school of thought, these particles were invisible to the naked eye but they had their own structure and could not be cut (temno) into any smaller particles: they were a-temnos – ‘the uncuttable thing’: the atom. Everything that you see or feel, these materialists argued, was made up of two things: atoms and space ‘in which these bodies are and through which they move this way and that’. Even living creatures were made from them: humans were, as one (hostile) author summarized, not made by God but were instead nothing more than ‘a haphazard union of elements’. The distinct species of animals were explained by a form of proto-Darwinism. As the Roman poet and atomist Lucretius wrote, nature put forth many species. Those that had useful characteristics – the fox and its cunning, say, or the dog and its intelligence – survived, thrived and reproduced. Those creatures that lacked these ‘lay at the mercy of others for prey and profit . . . until nature brought that race to destruction’.

To protest about bullfighting in Spain, the eating of dogs in South Korea, or the slaughter of baby seals in Canada while continuing to eat eggs from hens who have spent their lives crammed into cages, or veal from calves who have been deprived of their mothers, their proper diet, and the freedom to lie down with their legs extended, is like denouncing apartheid in South Africa while asking your neighbors not to sell their houses to blacks.

To preserve our absolute categories or ideals at the expense of human lives offends equally against the principles of science and of history; it is an attitude found in equal measure on the right and left wings in our days, and is not reconcilable with the principles accepted by those who respect the facts.

To prove to an indignant questioner on the spur of the moment that the work I do was useful seemed a thankless task and I gave it up. I turned to him with a smile and finished, 'To tell you the truth we don't do it because it is useful but because it's amusing.' The answer was thought of and given in a moment: it came from deep down in my mind, and the results were as admirable from my point of view as unexpected. My audience was clearly on my side. Prolonged and hearty applause greeted my confession. My questioner retired shaking his head over my wickedness and the newspapers next day, with obvious approval, came out with headlines 'Scientist Does It Because It's Amusing!' And if that is not the best reason why a scientist should do his work, I want to know what is. Would it be any good to ask a mother what practical use her baby is? That, as I say, was the first evening I ever spent in the United States and from that moment I felt at home. I realised that all talk about science purely for its practical and wealth-producing results is as idle in this country as in England. Practical results will follow right enough. No real knowledge is sterile. The most useless investigation may prove to have the most startling practical importance: Wireless telegraphy might not yet have come if Clerk Maxwell had been drawn away from his obviously 'useless' equations to do something of more practical importance. Large branches of chemistry would have remained obscure had Willard Gibbs not spent his time at mathematical calculations which only about two men of his generation could understand. With this trust in the ultimate usefulness of all real knowledge a man may proceed to devote himself to a study of first causes without apology, and without hope of immediate return.

To reduce sensation to a science, to make psychological analysis into a microscopically precise method - that's the goal that occupies, like a steady thirst, the hub of my life's will.

Torque was the greatest thing in the world, as far as Lina was concerned.

To satisfy our doubts . . . it is necessary that a method should be found by which our beliefs may be determined by nothing human, but by some external permanency -- by something upon which our thinking has no effect. . . . Our external permanency would not be external, in our sense, if it was restricted in its influence to one individual. It must be something which affects, or might affect, every man. And, though these affections are necessarily as various as are individual conditions, yet the method must be such that the ultimate conclusion of every man shall be the same. Such is the method of science. Its fundamental hypothesis, restated in more familiar language, is this: There are Real things, whose characters are entirely independent of our opinions about them; those Reals affect our senses according to regular laws, and, though our sensations are as different as are our relations to the objects, yet, by taking advantage of the laws of perception, we can ascertain by reasoning how things really and truly are; and any man, if he have sufficient experience and he reason enough about it, will be led to the one True conclusion. The new conception here involved is that of Reality.

The new conception here involved is that of Reality. It may be asked how I know that there are any Reals. If this hypothesis is the sole support of my method of inquiry, my method of inquiry must not be used to support my hypothesis. The reply is this: 1. If investigation cannot be regarded as proving that there are Real things, it at least does not lead to a contrary conclusion; but the method and the conception on which it is based remain ever in harmony. No doubts of the method, therefore, necessarily arise from its practice, as is the case with all the others. 2. The feeling which gives rise to any method of fixing belief is a dissatisfaction at two repugnant propositions. But here already is a vague concession that there is some one thing which a proposition should represent. Nobody, therefore, can really doubt that there are Reals, for, if he did, doubt would not be a source of dissatisfaction. The hypothesis, therefore, is one which every mind admits. So that the social impulse does not cause men to doubt it. 3. Everybody uses the scientific method about a great many things, and only ceases to use it when he does not know how to apply it. 4. Experience of the method has not led us to doubt it, but, on the contrary, scientific investigation has had the most wonderful triumphs in the way of settling opinion. These afford the explanation of my not doubting the method or the hypothesis which it supposes; and not having any doubt, nor believing that anybody else whom I could influence has, it would be the merest babble for me to say more about it. If there be anybody with a living doubt upon the subject, let him consider it.

To save wildlife and wild places the traction has to come not from the regurgitation of bad-news data but from the poets, prophets, preachers, professors, and presidents who have always dared to inspire.

To say that science is the measure of all true knowledge is not a scientific truth but a philosophic claim about science. It's scientism posing as science.

To shew thee such tokens I have leave; and if thou wilt pray again, and weep as now, and fast even days, thou shall hear yet greater things.

To talk of diseases is a sort of Arabian Nights entertainment.

To study the self is to forget the self. Maybe if you sat enough zazen, your sense of being a solid, singular self would dissolve and you could forget about it. What a relief. You could just hang out happily as part of an open-ended quantum array.

To suppose that the eye with all its inimitable contrivances for adjusting the focus to different distances, for admitting different amounts of light, and for the correction of spherical and chromatic aberration, could have been formed by natural selection, seems, I confess, absurd in the highest degree...The difficulty of believing that a perfect and complex eye could be formed by natural selection , though insuperable by our imagination, should not be considered subversive of the theory.

To the man of science, on his unassuming and laborious travels, which must often enough be journeys through the desert, there appear those glittering mirages called 'philosophical systems'; with bewitching deceptive power they show the solution of all enigmas and the freshest draught of the true water of life to be near at hand; his heart rejoices, and it seems to the weary traveller that his lips already touch the goal of all the perseverance and sorrows of the scientific life... Other natures again, may well grow exceedingly ill-humoured and curse the salty taste which these apparitions leave behind in the mouth and from which arises a raging thirst – without one having been brought so much as a step nearer to any kind of spring.

To this day, scientists know of only two layers of sediment 'broadly distributed across several continents that exhibit coeval abundance peaks in a comprehensive assemblage of cosmic impact markers, including nanodiamonds, high-temperature quenched spherules, high-temperature melt-glass, carbon spherules, iridium and aciniform carbon.' These layers are found at the Cretaceous-Paleogene Boundary 65 million years ago, when it has long been agreed that a gigantic cosmic impact in the Gulf of Mexico caused the mass extinction of the dinosaurs, and at the Younger Dryas Boundary 12,800 years ago.

To understand what a person is, it is necessary always to refer to what he may be in the future, for every state of the person is pointed in the direction of future possibilities.

To trust immediate intuitions rather than collective examination that is rational, careful, and intelligent is not wisdom: it is the presumption of an old man who refuses to believe that the great world outside his village is any different from the one that he has always known.

Tout y est sobre, exact, nu, précis, correct. Un phare est un chiffre

To understand this new frontier, I will have to try to master one of the most difficult and counterintuitive theories ever recorded in the annals of science: quantum physics. Listen to those who have spent their lives immersed in this world and you will have a sense of the challenge we face. After making his groundbreaking discoveries in quantum physics, Werner Heisenberg recalled, "I repeated to myself again and again the question: Can nature possibly be so absurd as it seemed to us in these atomic experiments?" Einstein declared after one discovery, "If it is correct it signifies the end of science." Schrödinger was so shocked by the implications of what he'd cooked up that he admitted, "I do not like it and I am sorry I had anything to do with it." Nevertheless, quantum physics is now one of the most powerful and well-tested pieces of science on the books. Nothing has come close to pushing it off its pedestal as one of the great scientific achievements of the last century. So there is nothing to do but to dive headfirst into this uncertain world. Feynman has some good advice for me as I embark on my quest: "I am going to tell you what nature behaves like. If you will simply admit that maybe she does behave like this, you will find her a delightful, entrancing thing. Do not keep saying to yourself, if you can possibly avoid it, 'But how can it be like that?' because you will get 'down the drain,' into a blind alley from which nobody has yet escaped. Nobody knows how it can be like that.

To us investigators, the concept 'soul' is irrelevant and a matter for laughter.

Toward the end of his book, Miller explains his need to unite science and religion: science does not explain the meaning and purpose of life. That may be, but why should we assume religion explains such things any better? Just because religion attempts to answer such questions does not mean its answers are correct. And such answers never seem to achieve any consensus. What is the meaning of life? Your answer is as good as mine--or just as bad.

True hope has no room for delusion.

[...] true hedonic engineering, as distinct from mindless hedonism or reckless personal experimentation, can be profoundly good for our character. Character-building technologies can benefit utilitarians and non-utilitarians alike. Potentially, we can use a convergence of biotech, nanorobotics and information technology to gain control over our emotions and become better (post-)human beings, to cultivate the virtues, strength of character, decency, to become kinder, friendlier, more compassionate: to become the type of (post)human beings that we might aspire to be, but aren't, and biologically couldn't be, with the neural machinery of unenriched minds. Given our Darwinian biology, too many forms of admirable behaviour simply aren't rewarding enough for us to practise them consistently: our second-order desires to live better lives as better people are often feeble echoes of our baser passions.

True Relations never break and relation which breaks were never true

True understanding is an indivisible land of liberation beyond all judgement and all conclusions.

Truly, Buffon was the father of all thought in natural history in the second half of the 18th century.

Truth is not as pompous and romantic as myth ... but it has the immeasurable value of being the Truth.

True understanding is an indivisible land of liberation beyond all judgement and all conclusions. In that land only will we be able to build a true castle of actual human civilization, with conscience flowing through its nerve center, stronger than all instinctual, primitive traits of the animal within.

Truly the light is sweet, and a pleasant thing it is for the eyes to behold the sun: But if a man live many years, and rejoice in them all; yet let him remember the days of darkness; for they shall be many. And all that cometh is vanity.

Truth is not a right to be claimed, but a gift for those who are able to conquer it. ☥

Truth is not a science. Virtue is not a faith. Love is not a religion.

Truth is not a thing Or a concept. It is as multidimensional In its meaning As it is in its reflection. It is both invisible And visible. It carries tons of weight, But can be carried. It is understood first through the spirit Before science, And felt in the heart, Before the mind. Truth is not always heard by reason, Because reason sometimes Ignores Truth. Always listen to your conscience. Your conscience is your heart And reason is your mind. Your mind is simply there to reason With your heart. But remember, Truth is in your heart, And only through your heart Can you connect to the light of God. He who is not motivated by his heart Will not see Truth, And he who thinks only with his mind Will be blind to Truth. He who does not think With his conscience, Does not stand by God, For the language of light Can only be decoded by the heart. He who reads and recites words of God Also does not stand by God – If he merely understands Words with his mind But not his heart. Truth is black and white, And the entire spectrum Of colors in-between. It can have many parts, But has a solid foundation. Truth lacks perfection, For it is the reflection of all, Yet its reflection as a whole, Is more beautiful Than the accumulated flaws Of the small. Truth is the only brand Worth breathing And believing. So stand for truth In everything you do, And only then Does your life have Meaning.

Try and penetrate with our limited means the secrets of nature and you will find that, behind all the descernible laws and connections, there remains something subtle, intangible and inexplicable. Veneration for this force beyond anything that we can comprehend is my religion. To that extent I am, in fact, religious.

Try harder to learn, than to shine

Tutku insanın, amaçlarına ulaşma çabası gösterme yeteneğidir.

Truth, independent of the Self, is irrelevant to the biological existence of human life.

Truths are as much a matter of questions as answers.

Try to remember that artists in these catastrophic times, along with the serious scientists, are the only salvation for us, if there is to be any.

Two moral forces shaped how we think and live in this shining twentieth century: the Virgin, and the Dynamo. The Dynamo represents the desire to know; the Virgin represents the freedom not to know. What's the Virgin made of? Things that we think are silly, mostly. The peculiar logic of dreams, or the inexplicable stirring we feel when we look on someone that's beautiful not in a way that we all agree is beautiful, but the unique way in which a single person is. The Virgin is faith and mysticism; miracle and instinct; art and randomness. On the other hand, you have the Dynamo: the unstoppable engine. It finds the logic behind a seeming miracle and explains that miracle away; it finds the order in randomness to which we're blind; it takes the caliper to a young woman's head and quantifies her beauty in terms of pleasing mathematical ratios; it accounts for the secret stirring you felt by discoursing at length on the nervous systems of animals.

Ultimately amorality is immorality.

Uhyggelige karle, disse videnskabsmænd. Slikt fritænkervæsen!

Umut, yaşamaya ve büyümeye eşlik eden, onunla birlikte bulunan bir ruhsal öğedir. Eğer güneş almayan bir ağaç, gövdesini güneşin geldiği yöne eğerse, ağacın, tıpkı insan gibi "umut ettiğini" söyleyemeyiz; çünkü insandaki umut, bir ağaç için söz konusu edilemeyecek duyguları ve farkında olmayı içerir. Ama gene de ağacın güneşin gelmesini umduğunu, ve gövdesini güneşe doğru bükmekle bu umudu dile getirdiğini söylemek yanlış değildir.

Una científica compañera mía me contaba un reciente viaje que realizó a la meseta de Nueva Guinea, donde visitó una tribu todavía en la edad de piedra que apenas había tenido contactos con la civilización. Ignoraban lo que son los relojes de pulsera, las bebidas refrescantes y los alimentos congelados. Pero conocían el Apolo 11. Sabían que los humanos han pisado la Luna.

Understanding requires insight. Insight must be anchored.

Two powerful factors which creates difference between destroying your relationship and deepening it are EGO and Attitude

Umut, inanç'a eşlik eden ruh halidir. Umutluluk hali olmaksızın inanç ayakta duramaz, dayanıksız kalır. Umut yalnız ve yalnız inanç temeli üzerinde durabilir.
