The discipline, nonetheless, is exacting: everything that can be observed should be observed, even if it is only recalled as the bland background from which the intriguing bits pop out like Venus in the evening sky. The goal is always finding something new, hopefully unimagined and, better still, hitherto unimaginable.
Karl Barry Sharpless
The Heisenberg principle - If something is closely observed, the odds are it is going to be altered in the process. The more a price pattern is observed by speculators the more prone you have false signals; the more the market is a product of nonspeculative activity, the greater the significance of technical breakout
All good intellects have repeated, since Bacon's time, that there can be no real knowledge but that which is based on observed facts. This is incontestable, in our present advanced stage; but, if we look back to the primitive stage of human knowledge, we shall see that it must have been otherwise then. If it is true that every theory must be based upon observed facts, it is equally true that facts cannot be observed without the guidance of some theory. Without such guidance, our facts would be desultory and fruitless; we could not retain them: for the most part we could not even perceive them.
Tessa distinguished absolutely between pain observed and pain shared. Pain observed is journalistic pain. It's diplomatic pain. It's television pain, over as soon as you switch off your beastly set. Those who watch suffering and do nothing about it, in her book, were little better than those who inflicted it. They were the bad Samaritans.
John le Carre
One of the most difficult features of direct experince is that it is unfiltered by any theories or expectations. It's hard to observe without imposing a theory to explain what we're seeing, but the trouble with theories, as Einstein said, is that they explain not only what is observed, but what can be observed. We start to build expectations based on our theories.
The hypotheses which we accept ought to explain phenomena which we have observed. But they ought to do more than this; our hypotheses ought to foretell phenomena which have not yet been observed; ... because if the rule prevails, it includes all cases; and will determine them all, if we can only calculate its real consequences. Hence it will predict the results of new combinations, as well as explain the appearances which have occurred in old ones. And that it does this with certainty and correctness, is one mode in which the hypothesis is to be verified as right and useful.
As to those other things which we hold on the authority, not of Scripture, but of tradition, and which are observed throughout the whole world, it may be understood that they are held as approved and instituted either by the apostles themselves, or by plenary Councils, whose authority in the Church is most useful, e.g. the annual commemoration, by special solemnities, of the Lord's passion, resurrection, and ascension, and of the descent of the Holy Spirit from heaven, and whatever else is in like manner observed by the whole Church wherever it has been established.
If the Commission is to enquire into the conditions "to be observed," it is to be presumed that they will give the result of their enquiries; or, in other words, that they will lay down, or at least suggest, "rules" and "conditions to be (hereafter) observed" in the construction of bridges, or, in other words, embarrass and shackle the progress of improvement to-morrow by recording and registering as law the prejudices or errors of to-day.

I have observed several hundred salespeople who were taught to use deceptive practices like 'bait and switch' and encouraged to play negotiation games with customers. They were so stressed by this behavior that they suffered from a high incidence of alcohol and substance abuse, divorce, job-jumping, and low productivity. In the same industry, I have observed countless people who had been taught to sell with high integrity. Ironically, their customer satisfaction, profit margins, and salesperson retention were significantly higher.
It has been observed in all ages that the advantages of nature or of fortune have contributed very little to the promotion of happiness; and that those whom the splendour of their rank, or the extent of their capacity, have placed upon the summits of human life, have not often given any just occasion to envy in those who look up to them from a lower station; whether it be that apparent superiority incites great designs, and great designs are naturally liable to fatal miscarriages; or that the general lot of mankind is misery, and the misfortunes of those whose eminence drew upon them an universal attention, have been more carefully recorded, because they were more generally observed, and have in reality only been more conspicuous than others, not more frequent, or more severe.
Did you really think we want those laws observed?" said Dr. Ferris. "We want them to be broken. You'd better get it straight that it's not a bunch of boy scouts you're up against... We're after power and we mean it... There's no way to rule innocent men. The only power any government has is the power to crack down on criminals. Well, when there aren't enough criminals one makes them. One declares so many things to be a crime that it becomes impossible for men to live without breaking laws. Who wants a nation of law-abiding citizens? What's there in that for anyone? But just pass the kind of laws that can neither be observed nor enforced or objectively interpreted - and you create a nation of law-breakers - and then you cash in on guilt. Now that's the system, Mr. Reardon, that's the game, and once you understand it, you'll be much easier to deal with.
What caused me to undertake the catalog was the nebula I discovered above the southern horn of Taurus on September 12, 1758, while observing the comet of that year... This nebula had such a resemblance to a comet in its form and brightness that I endeavored to find others, so that astronomers would not confuse these same nebulae with comets just beginning to shine. I observed further with suitable refractors for the discovery of comets, and this is the purpose I had in mind in compiling the catalog. After me, the celebrated Herschel published a catalog of 2000 which he has observed. This unveiling the sky, made with instruments of great aperture, does not help in the perusal of the sky for faint comets. Thus my object is different from his, and I need only nebulae visible in a telescope of two feet [focal length].
