One thing that being a scientist has taught me is that you can never be certain about anything. You never know the truth. You can only approach it and hope to get a bit nearer to it each time. You iterate towards the truth. You don't know it.

People have often said to me, 'Surely when you are with the tramps they don't really accept you as one of themselves? Surely they notice that you are different--notice the difference of accent?' etc., etc. As a matter of fact, a fair proportion of tramps, well over a quarter I should say, notice nothing of the kind. To begin with, many people have no ear for accent and judge you entirely by your clothes. I was often struck by this fact when I was begging at back doors. Some people were obviously surprised by my 'educated' accent, others completely failed to notice it; I was dirty and ragged and that was all they saw. Again, tramps come from all parts of the British Isles and the variation in English accents is enormous. A tramp is used to hearing all kinds of accents among his mates, some of them so strange to him that he can hardly understand them, and a man from, say, Cardiff or Durham or Dublin does not necessarily know which of the south English accents is an 'educated' one. In any case men with 'educated' accents, though rare among tramps, are not unknown. But even when tramps are aware that you are of different origin from themselves, it does not necessarily alter their attitude. From their point of view all that matters is that you, like themselves, are 'on the bum'. And in that world it is not done to ask too many questions. You can tell people the history of your life if you choose, and most tramps do so on the smallest provocation, but you are under no compulsion to tell it and whatever story you tell will be accepted without question. Even a bishop could be at home among tramps if he wore the right clothes; and even if they knew he was a bishop it might not make any difference, provided that they also knew or believed that he was genuinely destitute. Once you are in that world and seemingly of it, it hardly matters what you have been in the past. It is a sort of world-within-a-world where everyone is equal, a small squalid democracy...

George Orwell, The Road to Wigan

Never give up. Keep your thoughts and your mind always on the goal.

Tom Bradley

The key to your happiness is to own your slippers, own who you are, own how you look, own your family, own the talents you have, and own the ones you don't. If you keep saying your slippers aren't yours, then you'll die searching, you'll die bitter, always feeling you were promised more. Not only our actions, but also our omissions, become our destiny.

Abraham Verghese

I am your anointed Queen. I will never be by violence constrained to do anything. I thank God I am endued with such qualities that if I were turned out of the Realm in my petticoat I were able to live in any place in Christendom.

Elizabeth I

I want to talk about jobs and health care and pension security and what we're going to do to stop the brain drain in Ohio and make it possible for our young people to stay here and build a life in Ohio rather than in Pennsylvania or West Virginia or God knows where.

Ted Strickland

Man, alone, has the power to transform his thoughts into physical reality; man, alone, can dream and make his dreams come true.

Napoleon Hill

If the skies fall, one may hope to catch larks.

Francois Rabelais

To me there is no picture so beautiful as smiling, bright-eyed, happy children; no music so sweet as their clear and ringing laughter.

P. T. Barnum

Be true to the game, because the game will be true to you. If you try to shortcut the game, then the game will shortcut you. If you put forth the effort, good things will be bestowed upon you. That's truly about the game, and in some ways that's about life too.

Michael Jordan

It is remarkable how many misconceptions there are here about life in the developing world and I think that that knowledge gap has done a lot to contribute to the imbalance quite frankly.

Emma Thompson

The history of science is everywhere speculative. It is a marvelous hiatory. It makes you proud to be a human being.

Karl R. Popper

Never, my dear Sir, do you take it into your head that I do not love you; you may settle yourself in full confidence both of my love and my esteem; I love you as a kind man, I value you as a worthy man, and hope in time to reverence you as a man of exemplary piety.

Samuel Johnson
