Faith and doubt both are needed - not as antagonists but working side by side to take us around the unknown curve.

The failure of the system to deal quickly was attributable to Nixon's lying stonewalling and refusal to come clean. So it took 26 months for the final truth to be known.

Fear stifles our thinking and actions. It creates indecisiveness that results in stagnation. I have known talented people who procrastinate indefinitely rather than risk failure. Lost opportunities cause erosion of confidence and the downward spiral begins.

The world is divided into two categories: failures and unknowns.

Failure is a word unknown to me.

As is known it is in the realm of experience inaugurated by psychoanalysis that we may grasp along what imaginary lines the human organism in the most intimate recesses of its being manifests its capture in a symbolic dimension.

I was an only child. I've known only children. From this experience I do believe that the children should outnumber the parents.

Very often I've known people who wouldn't say a word to each other but they'd go to see movies together and experience life that way.

Fame will go by and so long I've had you fame. If it goes by I've always known it was fickle. So at least it's something I experience but that's not where I live.

In a state therefore of great equality and virtue where pure and simple manners prevailed the increase of the human species would evidently be much greater than any increase that has been hitherto known.

Address these environmental issues and you will address every issue known to man. And we keep dabbling in things that aren't really that important in the long term.

Some types of environmental restoration projects are well-known restored wetlands for instance or coal mine reclamation projects. Recently though larger dam removal projects have started a number of them in Washington state.

In every case the environmental hazards were made known only by independent scientists who were often bitterly opposed by the corporations responsible for the hazards.

Prejudices it is well known are most difficult to eradicate from the heart whose soil has never been loosened or fertilized by education they grow firm there firm as weeds among stones.

'Dreams From My Father' reveals more about Obama than is usually known about political leaders until after they're dead. Perhaps more than it intends it shows his mind working in real time sentence by sentence in what feels like a private audience with the reader.

Do not suppose however that I intend to urge a diet of classics on anybody. I have seen such diets at work. I have known people who have actually read all or almost all the guaranteed Hundred Best Books. God save us from reading nothing but the best.

Once the product's task is known design the interface first then implement to the interface design.

By the fourth grade I graduated to an erector set and spent many happy hours constructing devices of unknown purpose where the main design criterion was to maximize the number of moving parts and overall size.

We used to be referred to as bakers and then we became known as cake decorators and now we are known as cake designers. I teach at the French Culinary Institute in New York and cake design is a legitimate profession.

Wherever there is a design that is highly successful in a broad range of similar environments it is apt to emerge again and again independently - the phenomenon known in biology as convergent evolution. I call these designs 'good tricks.'

Through no divine design or cosmic plan we have inherited the mantle of life's caretaker on the earth the only home we have ever known.

Design is an unknown.

Perhaps we don't need these religious concoctions to pillow the fear of death. Just the fact that there is an unknown and something greater can bring a feeling of peace. That's enough for me.

Policemen so cherish their status as keepers of the peace and protectors of the public that they have occasionally been known to beat to death those citizens or groups who question that status.
