“In the penultimate decade of the twentieth century science is sufficiently advanced to resolve the puzzles that stymied scientists in the last century and demonstrate, without metaphysical speculation, the consistency of evolution in all realms of experience. It is now possible to advance a general evolution theory based on unitary and mutually consistent concepts derived from the empirical sciences.”

“The best case scenario is a rapid attack by precision-guided weapons, striking Saddam's communications in the first hours and preventing his deranged orders from being obeyed. Then a massive landing will bring food, medicine and laptop computers to a surging crowd of thankful and relieved Iraqis and Kurds. This could, in theory, all happen.”

“The planet is fine. The people are [bleeped out]. Because everyone is trying to save the planet. The planet doesn’t need that. The planet will take care of itself. People are selfish. And that's what they're doing is trying to save the planet for themselves to have a nicer place to live. They don't care about the planet in theory. They just care about having a comfortable place. And these people with the fires and the floods and everything, they overbuild, they put nature to the test and they get what's coming to them. That's what I say. That's what's happening, and I can't wait for the sea levels to rise. I can't wait for some of these cities to disappear. There are places that are going to go away. The map is going to change and that's because -- people think nature is outside of them. They don't take into them the idea that we are part of it. They say, "oh, we're going for a nature walk. We're going to the country because we like nature." Nature is in here. [points to chest] And if you're in tune with it, like the Indians, the Hopis, especially, the balance of life, the balance, the harmony of nature, if you understand that, you don't overbuild. You don’t do all this moron stuff.”

“The actual evolution of mathematical theories proceeds by a process of induction strictly analogous to the method of induction employed in building up the physical sciences; observation, comparison, classification, trial, and generalisation are essential in both cases. Not only are special results, obtained independently of one another, frequently seen to be really included in some generalisation, but branches of the subject which have been developed quite independently of one another are sometimes found to have connections which enable them to be synthesised in one single body of doctrine. The essential nature of mathematical thought manifests itself in the discernment of fundamental identity in the mathematical aspects of what are superficially very different domains. A striking example of this species of immanent identity of mathematical form was exhibited by the discovery of that distinguished mathematician... Major MacMahon, that all possible Latin squares are capable of enumeration by the consideration of certain differential operators. Here we have a case in which an enumeration, which appears to be not amenable to direct treatment, can actually be carried out in a simple manner when the underlying identity of the operation is recognised with that involved in certain operations due to differential operators, the calculus of which belongs superficially to a wholly different region of thought from that relating to Latin squares.”

“To be in the margin is to be part of the whole but outside the main body. As black Americans living in a small Kentucky town, the railroad tracks were a daily reminder of our marginality. Across those tracks were paved streets, stores we could not enter, restaurants we could not eat in, and people we could not look directly in the face. Across those tracks was a world we could work in as maids, as janitors, as prostitutes, as long as it was in a service capacity. We could enter that world but we could not live there. We had always to return to the margin, to cross the tracks, to shacks and abandoned houses on the edge of town. There were laws to ensure our return. To not return was to risk being punished. Living as we did-on the edge-we developed a particular way of seeing reality. We looked both from the outside in and and from the inside out. We focused our attention on the center as well as on the margin. We understood both. This mode of seeing reminded us of the existence of a whole universe, a main body made up of both margin and center. Our survival depended on an ongoing public awareness of the separation between margin and center and an ongoing private acknowledgment that we were a necessary, vital part of that whole. This sense of wholeness, impressed upon our consciousness by the structure of our daily lives, provided us an oppositional world view-a mode of seeing unknown to most of our oppressors, that sustained us, aided us in our struggle to transcend poverty and despair, strengthened our sense of self and our solidarity. … Much feminist theory emerges from privileged women who live at the center, whose perspectives on reality rarely include knowledge and awareness of the lives of women and men who live in the margin. As a consequence, feminist theory lacks wholeness, lacks the broad analysis that could encompass a variety of human experiences. Although feminist theorists are aware of the need to develop ideas and analysis that encompass a larger number of experiences, that serve to unify rather than to polarize, such theory is complex and slow in formation. At its most visionary, it will emerge from individuals who have knowledge of both margin and center.”

“It has been observed here this morning that we are called fanatics. Bless me! That is nothing. Who has not been called a fanatic who has discovered anything new in philosophy or science? We have all read of Galileo the astronomer who, contrary to the system of astronomy that had been received for ages before his day, taught that the sun, and not the earth, was the centre of our planetary system? For this the learned astronomer was called "fanatic," and subjected to persecution and imprisonment of the most rigorous character. So it has been with others who have discovered and explained new truths in science and philosophy which have been in opposition to long-established theories; and the opposition they have encountered has endured until the truth of their discoveries has been demonstrated by time. The term "fanatic" is not applied to professors of religion only…I will tell you who the real fanatics are: they are they who adopt false principles and ideas as facts, and try to establish a superstructure upon a false foundation. They are the fanatics; and however ardent and zealous they may be, they may reason or argue on false premises till doomsday, and the result will be false. If our religion is of this character we want to know it; we would like to find a philosopher who can prove it to us. We are called ignorant; so we are: but what of it? Are not all ignorant? I rather think so. Who can tell us of the inhabitants of this little planet that shines of an evening, called the moon? When we view its face we may see what is termed "the man in the moon," and what some philosophers declare are the shadows of mountains. But these sayings are very vague, and amount to nothing; and when you inquire about the inhabitants of that sphere you find that the most learned are as ignorant in regard to them as the most ignorant of their fellows. So it is with regard to the inhabitants of the sun. Do you think it is inhabited? I rather think it is. Do you think there is any life there? No question of it; it was not made in vain. It was made to give light to those who dwell upon it, and to other planets; and so will this earth when it is celestialized. Every planet in its first rude, organic state receives not the glory of God upon it, but is opaque; but when celestialized, every planet that God brings into existence is a body of light, but not till then. Christ is the light of this planet. God gives light to our eyes.”

“There is a right and legitimate Pan-Islamism to which every sincere and believing Mahomedan belongs--that is, the theory of the spiritual brotherhood and unity of the children of the Prophet. It is a deep, perennial element in that Perso-Arabian culture, that great family of civilisation to which we gave the name Islamic in the first chapter. It connotes charity and goodwill towards fellow-believers everywhere…It means an abiding interest in the literature of Islam, in her beautiful arts, in her lovely architecture, in her entrancing poetry. It also means a true reformation -- a return to the early and pure simplicity of the faith, to its preaching by persuasion and argument, to the manifestation of a spiritual power in individual lives, to beneficent activity for mankind. This natural and worthy spiritual movement makes not only the Master and His teaching but also His children of all climes an object of affection to the Turk or the Afghan, to the Indian or the Egyptian. A famine or a desolating fire in the Moslem quarters of Kashgar or Sarajevo would immediately draw the sympathy and material assistance of the Mahomedan of Delhi or Cairo. The real spiritual and cultural unity of Islam must ever grow, for to the follower of the Prophet it is the foundation of the life of the soul.”

“I had no idea what I was doing when I wrote Search. There was no carefully designed work plan. There was no theory that I was out to prove. I went out and talked to genuinely smart, remarkably interesting, first-rate people. I had an infinite travel budget that allowed me to fly first class and stay at top-notch hotels and a license from McKinsey to talk to as many cool people as I could all around the United States and the world.
I went to see Karl Weick, who had totally influenced my life. I had read his work a thousand times, and I'd never met him. I went to Oslo to talk with Einar Thorsrud, who had studied empowerment on oil tankers. I went to the Tavistock Institute in London, where the leading thinkers on organizational development were looking at why people work together effectively in team configurations under certain circumstances.
Word of the meeting got back to McKinsey USA, and I was invited to give a presentation to the top management of PepsiCo… The time was drawing near for the Pepsi presentation to take place. One morning at about 6, I sat down at my desk overlooking the San Francisco Bay from the 48th floor of the Bank of America Tower, and I closed my eyes. Then I leaned forward, and I wrote down eight things on a pad of paper. Those eight things haven't changed since that moment. They were the eight basic principles of Search.”

“Both the law of inertia and the law of gravitation contain a numerical factor or a constant belonging to matter, which is called mass. We have thus two definitions of mass; one by the law of inertia: mass is the ratio between force and acceleration. We may call the mass thus defined the inertial or passive mass, as it is a measure of the resistance offered by matter to a force acting on it. The second is defined by the law of gravitation, and might be called the gravitational or active mass, being a measure of the force exerted by one material body on another. The fact that these two constants or coefficients are the same is, in Newton's system, to be considered as a most remarkable accidental coincidence and was decidedly felt as such by Newton himself. He made experiments to determine the equality of the two masses by swinging a pendulum, of which the bob was hollow and could be filled up with different materials. The force acting on the pendulum is proportional to its active mass, its inertia is proportional to its passive mass, so that the period will depend on the ratio of the passive and the active mass. Consequently the fact that the period of all these different pendulums was the same, proves that this ratio is a constant, and can be made equal to unity by a suitable choice of units, i. e., the inertial and the gravitational mass are the same. These experiments have been repeated in the nineteenth century by Bessel, and in our own times by Eötvös and Zeeman, and the identity of the inertial and the gravitational mass is one of the best ascertained empirical facts in physics-perhaps the best. It follows that the so-called fictitious forces introduced by a motion of the body of reference, such as a rotation, are indistinguishable from real forces…. In Einstein's general theory of relativity there is also no formal theoretical difference, as there was in Newton's system…. the equality of inertial and gravitational mass is no longer an accidental coincidence, but a necessity.”

“It is remarkable that this generalization of plane geometry to surface geometry is identical with that generalization of geometry which originated from the analysis of the axiom of parallels. …the construction of non-Euclidean geometries could have been equally well based upon the elimination of other axioms. It was perhaps due to an intuitive feeling for theoretical fruitfulness that the criticism always centered around the axiom of parallels. For in this way the axiomatic basis was created for that extension of geometry in which the metric appears as an independent variable. Once the significance of the metric as the characteristic feature of the plane has been recognized from the viewpoint of Gauss' plane theory, it is easy to point out, conversely, its connection with the axiom of parallels. The property of the straight line as being the shortest connection between two points can be transferred to curved surfaces, and leads to the concept of straightest line; on the surface of the sphere the great circles play the role of the shortest line of connection… analogous to that of the straight line on the plane. Yet while the great circles as "straight lines" share the most important property with those of the plane, they are distinct from the latter with respect to the axiom of the parallels: all great circles of the sphere intersect and therefore there are no parallels among these "straight lines". …If this idea is carried through, and all axioms are formulated on the understanding that by "straight lines" are meant the great circles of the sphere and by "plane" is meant the surface of the sphere, it turns out that this system of elements satisfies the system of axioms within two dimensions which is nearly identical in all of it statements with the axiomatic system of Euclidean geometry; the only exception is the formulation of the axiom of the parallels.”

Hans Reichenbach (1891–1953) American philosopher

The geometry of the spherical surface can be viewed as the realization of a two-dimensional non-Euclidean geometry: the denial of the axiom of the parallels singles out that generalization of geometry which occurs in the transition from the plane to the curve surface.
