It may be trivial, but it certainly wasn't easy.
John Cowles, 2003 ACL2 Workshop

Why of course the people don't want war. Why should some poor slob on a farm want to risk his life in a war when the best he can get out of it is to come back to his farm in one piece? Naturally, the common people don't want war . . . But after all it is the leaders of the country who determine the policy, and it is always a simple matter to drag the people along, whether it is a democracy, or a fascist dictatorship, or a parliament, or a communist dictatorship ... Voice or no voice, the people can always be brought to the bidding of leaders. That is easy. All you have to do is tell them they are being attacked [and] denounce the pacifists for lack of patriotism and exposing the country to danger.
Herman Goering, Luftwaffe commander, at Nuremberg, 1946

I don't know who discovered water, but it wasn't a fish.

As soon as we started programming, we found to our surprise that it wasn't as easy to get programs right as we had thought. Debugging had to be discovered. I can remember the exact instant when I realized that a large part of my life from then on was going to be spent in finding mistakes in my own programs.
Maurice Wilkes discovers debugging, 1949

Sometimes I think about something and then I don't know any more when I'm done than I did when I started; but I don't let that stop me.

Beer is proof that God loves us and wants us to be happy.
Benjamin Franklin

It is only possible to succeed at second-rate pursuits -- like becoming a millionaire or a prime minister, winning a war, seducing a beautiful woman, flying through the stratosphere, or landing on the moon. First-rate pursuits -- involving, as they must, trying to understand what life is about and trying to convey that understanding -- inevitably result in a sense of failure. A Napoleon, a Churchill, a Roosevelt can feel themselves to be successful, but never a Socrates, a Pascal, a Blake. Understanding is forever unattainable. Therein lies the inevitability of failure in embarking upon its quest, which is nonetheless the only one worthy of serious attention.
Malcolm Muggeridge, 1965

There are two ways of constructing a software design: One way is to make it so simple that there are obviously no deficiencies, and the other way is to make it so complicated that there are no obvious deficiencies. The first method is far more difficult.

W. Edwards Deming

The complexity of practice has always dwarfed the simplicity of theory.
Robert Britcher

We choose our joys and sorrows long before we experience them.
Kahlil Gibran

Good words will not give my people good health and stop them from dying. Good words will not get my people a home where they can live in peace and take care of themselves. I am tired of talk that comes to nothing.
Chief Joseph

In spite of your religion you can be a good person.
