A colour is a physical object as soon as we consider its dependence, for instance, upon its luminous source, upon other colours, upon temperatures, upon spaces, and so forth.

The plain man is familiar with blindness and deafness, and knows from his everyday experience that the look of things is influenced by his senses; but it never occurs to him to regard the whole world as the creation of his senses.

When I recall today my early youth, I should take the boy that I then was, with the exception of a few individual features, for a different person, were it not for the existence of the chain of memories.

Thing, body, matter, are nothing apart from the combinations of the elements, - the colours, sounds, and so forth - nothing apart from their so-called attributes.

Many an article that I myself penned twenty years ago impresses me now as something quite foreign to myself.

Physics is experience, arranged in economical order.

Man is pre-eminently endowed with the power of voluntarily and consciously determining his own point of view.

The presentations and conceptions of the average man of the world are formed and dominated, not by the full and pure desire for knowledge as an end in itself, but by the struggle to adapt himself favourably to the conditions of life.

The biological task of science is to provide the fully developed human individual with as perfect a means of orientating himself as possible. No other scientific ideal can be realised, and any other must be meaningless.

Science always has its origin in the adaptation of thought to some definite field of experience.

A colour is a physical object as soon as we consider its dependence, for instance, upon its luminous source, upon other colours, upon temperatures, upon spaces, and so forth.

A movement that we will to execute is never more than a represented movement, and appears in a different domain from that of the executed movement, which always takes place when the image is vivid enough.

Personally, people know themselves very poorly.

The task which we have set ourselves is simply to show why and for what purpose we hold that standpoint during most of our lives, and why and for what purpose we are provisionally obliged to abandon it.

My table is now brightly, now dimly lighted. Its temperature varies. It may receive an ink stain. One of its legs may be broken. It may be repaired, polished, and replaced part by part. But, for me, it remains the table at which I daily write.

Bodies do not produce sensations, but complexes of elements (complexes of sensations) make up bodies.

If our dreams were more regular, more connected, more stable, they would also have more practical importance for us.

Similarly, many a young man, hearing for the first time of the refraction of stellar light, has thought that doubt was cast on the whole of astronomy, whereas nothing is required but an easily effected and unimportant correction to put everything right again.

The fact is, every thinker, every philosopher, the moment he is forced to abandon his one-sided intellectual occupation by practical necessity, immediately returns to the general point of view of mankind.

Without renouncing the support of physics, it is possible for the physiology of the senses, not only to pursue its own course of development, but also to afford to physical science itself powerful assistance.

Ordinarily pleasure and pain are regarded as different from sensations.

The ego is as little absolutely permanent as are bodies.

At times, we were forced to go through a history of dependence, unable to determine our own destiny. But today, we are at the threshold of a new turning point.

Schools are successful only insofar as they reduce the dependence of a child's opportunities upon his social origins.

The real message of the Dance opens up the vistas of life to all who have the urge to express beauty with no other instrument than their own bodies, with no apparatus and no dependence on anything other than space.

If the United States is to protect itself from the economic and the political threats created by this excessive dependence, we must reduce our reliance on foreign energy sources and on foreign oil as quickly and as efficiently as possible.

As the cost of gasoline rises and our dependence on foreign oil continues to increase, the effect of sending over $100 billion each year to OPEC nations hurts every American.

The price of indulging yourself in your youth in the things you cannot afford is poverty and dependence in your old age.

It is important that the United States move with all deliberate speed to develop and get into usage alternative fuels that will allow us to end our dependence on foreign oil.

One of my top priorities in Congress is to reduce U.S. dependence on fossil fuels.

If we don't continue to pursue alternative, emissions-free energy sources like nuclear fuel, we are at risk of increasing our dependence on costly natural gas.

The essence of religion consists in the feeling of an absolute dependence.

We need an energy revolution by breaking our dependence on fossil fuels, polluting fuels... I am very, very confident our small state will lead this. We will be noticed by the country and the world.

Well, for starters, we have to do more to create demand for new technologies that can reduce our dependence on foreign oil and environmental degradation.

True happiness is... to enjoy the present, without anxious dependence upon the future.

Ethanol has reduced our nation's dependence on imported energy, created thousands of jobs, reduced air pollution, and increased energy security. And renewable fuels cost less at the pump. It is a growth fuel that fuels opportunities for millions of Americans.

The provisions contained in this plan will ensure that the United States has the infrastructure necessary to meet energy needs through future decades, easing dependence on unpredictable foreign oil markets, and creating thousands of new jobs for American workers.

We need a balanced, long term energy policy to reduce our dependence on foreign oil and preserve the beauty of the land we love.

In spite of our poverty and our economic dependence, we do not have to give in, neither because we are sometimes abandoned nor because of the wish of some nations to impose their economic or political models.

The U.S. now imports over half of its oil supply from the Middle East. This dangerous dependence on foreign energy sources is an issue of national security.

It is probably not love that makes the world go around, but rather those mutually supportive alliances through which partners recognize their dependence on each other for the achievement of shared and private goals.

By reducing our dependence of foreign oil and increasing alternative energy sources such as ethanol, we can begin to bring down prices at the pumps, create thousands of new jobs and bring a much needed boost to our economy.

Our dependence on foreign energy sources is our Achilles heel, not just in the realm of diplomacy, but in terms of our future as the world's economic leader.

And I am a conservative. Sometimes conservatives forget we are supposed to conserve, to save, to be efficient. Plus our dependence on other sources of energy is causing our country to not be independent and to really be vulnerable. So this is a security issue.

The great city can teach something that no university by itself can altogether impart: a vivid sense of the largeness of human brotherhood, a vivid sense of man's increasing obligation to man; a vivid sense of our absolute dependence on one another.

Dependence begets subservience and venality, suffocates the germ of virtue, and prepares fit tools for the designs of ambition.

By encouraging renewable energy sources such as wind energy, we boost South Dakota's economy and we help reduce America's dependence on foreign oil.

A colour is a physical object as soon as we consider its dependence, for instance, upon its luminous source, upon other colours, upon temperatures, upon spaces, and so forth.

First, we have to find a common vocabulary for energy security. This notion has a radically different meaning for different people. For Americans it is a geopolitical question. For the Europeans right now it is very much focused on the dependence on imported natural gas.
