We cannot do everything in Africa, but doing nothing is not an option.
We cannot really love anyone with with whom we never laugh.
As I watch what is happening in the Middle East and the carnage that comes over our television screens every evening, I cannot help but ask myself, what is wrong with humankind that we cannot stop the killing?
Without food, we cannot survive, and that is why issues that affect the food industry are so important.
There's no reason why we cannot become smarter, more perfect, and maybe even live longer.
We cannot continue to close our eyes to the fact that we have to truly embrace green jobs, new technologies and alternative sources of energy.
One isn't necessarily born with courage, but one is born with potential. Without courage, we cannot practice any other virtue with consistency. We can't be kind, true, merciful, generous, or honest.
Without a doubt, first thing we should do is clean up our fiscal house, and that starts with balancing our budgets and digging out of this red ink. We cannot expect to continue in this fashion and remain the leader of the free world.
We are searching for some kind of harmony between two intangibles: a form which we have not yet designed and a context which we cannot properly describe.
Either we need to redefine what probable cause means and say that police are not subject to it, or we arrest officers right away just as we would with any other person accused of committing a crime. Either we write new laws or enforce existing ones; we cannot have it both ways.
For all of its uncertainty, we cannot flee the future.
No matter how many troops we have in place or how long they stay, we cannot impose a parliamentary democracy there any more than the insurgents can impose a theocracy.
Our first responsibility is to protect the American people and we cannot put on blinders to expect that everyone who seeks asylum does so in good faith.
It is claimed, but with what truth we cannot say, that there is a well-defined propaganda among the aliens of colour to bring about the degeneration of the white race.
There is no one thoroughly despicable. We cannot descend much lower than an idiot; and an idiot has some advantages over a wise man.
We cannot continually barricade ourselves under some falsified idea of race, because our idea of blackness and race is simply reactionary. Africans didn't walk around Africa being black and proud, they walked around proud.
Egypt is going through difficult times and we cannot allow it to carry on.
Employers will work you longer for less money and under questionable safety conditions because it is their duty to prioritize the bottom line. As individuals, we cannot complain. That's why we need a union to speak for us, certainly when our safety, our health, and our very lives are at stake!
We cannot conceive of matter being formed of nothing, since things require a seed to start from... Therefore there is not anything which returns to nothing, but all things return dissolved into their elements.
I have argued above that we cannot prevent the Singularity, that its coming is an inevitable consequence of the humans' natural competitiveness and the possibilities inherent in technology.
We cannot, of course, eliminate all accidents - no industry can do that.
We cannot be any stronger in our foreign policy for all the bombs and guns we may heap up in our arsenals than we are in the spirit which rules inside the country. Foreign policy, like a river, cannot rise above its source.
We cannot teach people anything; we can only help them discover it within themselves.
We cannot sacrifice innocent human life now for vague and exaggerated promises of medical treatments thirty of forty years from now. There are ways to pursue this technology and respect life at the same time.
We give advice, but we cannot give the wisdom to profit by it.
The race of mankind would perish did they cease to aid each other. We cannot exist without mutual help. All therefore that need aid have a right to ask it from their fellow-men; and no one who has the power of granting can refuse it without guilt.
If we attend continually and promptly to the little that we can do, we shall ere long be surprised to find how little remains that we cannot do.
My view is that we cannot be ruled by fear. When we do that, we are not making ourselves see. We are not thinking things through. We are not looking at what works.
We cannot make events. Our business is wisely to improve them.
We cannot have a separate group of people that are military and a separate civilian society. Otherwise, it's dangerous to democracy.
There are good reasons why natural selection has become widely accepted as an explanation of evolutionary development. When applied to mammals and other large animals, it fits perfectly. But we cannot assume that all evolutionary steps arise from selection, particularly when looking at smaller animals.
Equal and united people can above all become a part of the civilization toward which mankind is moving. If we cannot be at the head of the column leading to such a civilization, there is certainly no need for us to be at is tail.
We cannot tear out a single page of our life, but we can throw the whole book in the fire.
We cannot stop what we cannot see.
Small use it will be to save democracy for the race if we cannot save the race for democracy.
There are no rules for friendship. It must be left to itself. We cannot force it any more than love.
