I endeavoured to sketch out (and it was, I believe, the first systematic attempt to accomplish such a task) the laws which govern the extinction of species, with a view of showing that the slow, but ceaseless variations, now in progress in physical geography, together with the migration of plants and animals into new regions, must, in the course of ages, give rise to the occasional loss of some of them, and eventually cause an entire fauna and flora to die out; also, that we must infer, from geological data, that the places thus left vacant from time to time, are filled up without delay by new forms, adapted to new conditions, sometimes by immigration from adjoining provinces, sometimes by new creations. Among the many causes of extinction enumerated by me, were the power of hostile species, diminution of food, mutations in climate, the conversion of land into sea, and of sea into land, &c.

But before we attempt to set ourselves up as exponents of universal reform, it would be wise to remember that progress is of slow growth, and also to remember that moderation, patience, forbearance, and charity are virtues in their own right. The only action which can be effective in the long run is that which helps others to help themselves. Before we assume too great responsibilities in the governing of others, it would be the part of wisdom very completely to discharge our responsibilities for governing ourselves. A large amount of work has to be done at home before we can start in on the neighbors, and very considerable duties have to be performed in America before we undertake the direction of the rest of the world. But we must at all times do the best we can for ourselves without forgetting others, and the best we can for our own country without forgetting other nations.
Calvin Coolidge
The main preparation to be made for receiving in the physical vehicle the vibrations of the higher consciousness are: its purification from grosser materials by pure food and pure life; the entire subjugation of the passions, and the cultivation of an even, balanced temper and mind, unaffected by the turmoil and vicissitudes of external life; the habit of quiet meditation on lofty topics, turning the mind away from the objects of the senses, and from the mental images arising from them, and fixing it on higher things; the cessation of hurry, especially of that restless, excitable hurry of the mind, which keeps the brain continually at work and flying from one subject to another; the genuine love for the things of the higher world, that makes them more attractive than the objects of the lower, so that the mind rests contentedly in their companionship as in that of a well-loved friend.
Annie Besant
Difficult as the course is, the dangers do not come from the difficulties; they come from extremists in India and at home. I will tell you what I mean. I am firmly convinced that such writings as appear in such papers as the Daily Mail will do more to lose India for the British Empire, will do more to cause a revolutionary spirit, than anything that can be done in any way by anyone else. I got many letters, I need hardly say, of all points of view. I had a very characteristic one last week... It was from a colonel; he was an old man, you could tell that by his writing; and he used this phrase: He said, "You and Lord Irwin are negrophiles." Perhaps he was a member of the United Empire party. That is not the way to cement the Empire. This sort of thing, and the spirit behind it, will break up our Empire infallibly, and that is what I am out to fight.
Stanley Baldwin
There are two ways of considering society. According to some, the development of human associations is not subject to providential, unchangeable laws. Rather, these associations, having originally been organized in a purely artificial manner by primeval legislators, can later be modified or remade by other legislators, in step with the progress of social science. In this system the government plays a preeminent role, because it is upon it, the custodian of the principle of authority, that the daily task of modifying and remaking society devolves.According to others, on the contrary, society is a purely natural fact. Like the earth on which it stands, society moves in accordance with general, preexisting laws. In this system, there is no such thing, strictly speaking, as social science; there is only economic science, which studies the natural organism of society and shows how this organism functions.

It is true that we were cautious in our planning. There were many uncertainties about how well our Lunar module systems and our Pressure suit and backpack would match the engineering predictions in the hostile lunar environment. We were operating in a near perfect vacuum with the temperature well above 200 degrees Fahrenheit with the local gravity only one sixth that of Earth. That combination cannot be duplicated here on Earth, but we tried as best we could to test our equipment for those conditions. For example, because normal air conditioning is inadequate for lunar conditions, we were required to use cold water to cool the interior of our suits. We did not have any data to tell us how long the small water tank in our backpacks would suffice. NASA officials limited our surface working time to 2 and 3/4 hours on that first surface exploration to assure that we would not expire of hyperthermia.
