You can never know what is and what is not powerful, but you can always find out what the powerful people are scared of. A state like China looks so powerful, but they are so scared of the Internet, so the Internet is more powerful than them.
The strength required for the vision of the most powerful reality is not only compatible with the most powerful strength for action, for monstrous action, for crime - it even presupposes it.
An enormous amount of modern ingenuity is expended on finding defences for the indefensible conduct of the powerful. As I have said above, these defences generally exhibit themselves most emphatically in the form of appeals to physical science. And of all the forms in which science, or pseudo-science, has come to the rescue of the rich and stupid, there is none so singular as the singular invention of the theory of races.
Now, in practice, in daily social interactions, etc., there may be all kinds of biases and prejudices that are unspoken, that people aren't aware of, that affect who's hired, and who gets loans, and how kids are treated in school. But it's a powerful thing if you have on your side an idea that the overwhelming majority of people believe in because that's how you can build a consensus that's lasting.
Public opinion is a mysterious and invisible power, to which everything must yield. There is nothing more fickle, more vague, or more powerful; yet capricious as it is, it is nevertheless much more often true, reasonable, and just, than we imagine.
When a government becomes powerful it is destructive, extravagant and violent; it is an usurer which takes bread from innocent mouths and deprives honorable men of their substance, for votes with which to perpetuate itself.
What patient can trust the knowledge of a physician without reputation or furniture, in a period when publicity is all-powerful and when the government gilds the lamp posts on the Place de la Concorde in order to dazzle the poor?
We lose ourselves when we compromise the very ideals that we fight to defend. And we honor those ideals by upholding them not when it's easy, but when it is hard.
A page of Addison or of Irving will teach more of style than a whole manual of rules, whilst a story of Poe's will impress upon the mind a more vivid notion of powerful and correct description and narration than will ten dry chapters of a bulky textbook.
It is a true observation of ancient writers, that as men are apt to be cast down by adversity, so they, are easily satiated with prosperity, and that joy and grief produce the same effects. For whenever men are not obliged by necessity to fight they fight from ambition, which is so powerful a passion in the human breast that however high we reach we are never satisfied.
Again there is another great and powerful cause why the sciences have made but little progress; which is this. It is not possible to run a course aright when the goal itself has not been rightly placed.
The journey will be difficult. The road will be long. I face this challenge with profound humility, and knowledge of my own limitations. But I also face it with limitless faith in the capacity of the American people.
Imagination is everything.
It is the preview of life's coming attractions.
Imagination is more important than knowledge.
Never give up on what you really want to do.
The person with big dreams is more powerful than one with all the facts.
