“We may, indeed, set it down as an absolute certainty, that many things are erroneously deemed impossible; for, till we know all the possible—and how far we are from that need not be insisted on—how can we know what is impossible?”

— Robert Chambers (publisher, born 1802)

“I’m here to say we must reject such despair. I’m here to insist that we are not as divided as we seem. And I know that because I know America. I know how far we’ve come against impossible odds. I know we’ll make it because of what I’ve experienced in my own life, what I’ve seen of this country and its people -- their goodness and decency --as President of the United States. […] I see what's possible when we recognize that we are one American family, all deserving of equal treatment, all deserving of equal respect, all children of God. That’s the America that I know.”

Barack Obama (1961) 44th President of the United States of America

2016, Memorial Service for Fallen Dallas Police Officers (July 2016)
Context: Faced with this violence, we wonder if the divides of race in America can ever be bridged. We wonder if an African-American community that feels unfairly targeted by police, and police departments that feel unfairly maligned for doing their jobs, can ever understand each other’s experience. We turn on the TV or surf the Internet, and we can watch positions harden and lines drawn, and people retreat to their respective corners, and politicians calculate how to grab attention or avoid the fallout. We see all this, and it’s hard not to think sometimes that the center won't hold and that things might get worse. I understand how Americans are feeling. But, Dallas, I’m here to say we must reject such despair. I’m here to insist that we are not as divided as we seem. And I know that because I know America. I know how far we’ve come against impossible odds. I know we’ll make it because of what I’ve experienced in my own life, what I’ve seen of this country and its people -- their goodness and decency --as President of the United States. [... ] I see what's possible when we recognize that we are one American family, all deserving of equal treatment, all deserving of equal respect, all children of God. That’s the America that I know.

“Till we know that, what is all our knowledge; how shall we even so much as "detect?”

Thomas Carlyle (1795–1881) Scottish philosopher, satirical writer, essayist, historian and teacher

For the vulpine sharpness, which considers itself to be knowledge, and "detects" in that fashion, is far mistaken. Dupes indeed are many: but, of all dupes, there is none so fatally situated as he who lives in undue terror of being duped.
1840s, Heroes and Hero-Worship (1840), The Hero As King

“We know how to speak many falsehoods which resemble real things, but we know, when we will, how to speak true things.”

Hesiod Greek poet

We know to tell many fictions like to truths, and we know, when we will, to speak what is true.
We know how to tell many lies that pass for truth, and we know, when we wish, to tell the truth itself.

“There are perhaps only three things we can and need to know with certainty: where we are, where we want to be, and by what means we should maneuver the unclear territory between here and there.”

Mike Rother (1958) American business academic

“We absolutely must leave room for doubt or there is no progress and no learning. There is no learning without having to pose a question. And a question requires doubt. People search for certainty. But there is no certainty. People are terrified — how can you live and not know? It is not odd at all. You only think you know, as a matter of fact. And most of your actions are based on incomplete knowledge and you really don't know what it is all about, or what the purpose of the world is, or know a great deal of other things. It is possible to live and not know.”

“The idea behind structuralism is that there are things we may not know but we can learn how they are related to each other.”

Claude Lévi-Strauss (1908–2009) French anthropologist and ethnologist

As quoted in his obituary, Daily Telegraph (4 November 2009) http://www.telegraph.co.uk/news/obituaries/science-obituaries/6496558/Claude-Levi-Strauss.html
Context: The idea behind structuralism is that there are things we may not know but we can learn how they are related to each other. This has been used by science since it existed and can be extended to a few other studies — linguistics and mythology — but certainly not to everything.
The great speculative structures are made to be broken. There is not one of them that can hope to last more than a few decades, or at most a century or two.
