“Charlie Gleister had invented a time machine, but he hadn’t invented it right because it didn’t work.”

"Edward Witten" interview, Superstrings: A Theory of Everything? (1992) ed. P.C.W. Davies, Julian Brown
Context: It's been said that string theory is part of the physics of the twenty-first century that fell by chance into the twentieth century. That's a remark that was made by a leading physicist about fifteen years ago.... String theory was invented essentially by accident in a long series of events, starting with the Veneziano model... No one invented it on purpose, it was invented in a lucky accident.... By rights, string theory shouldn't have been invented until our knowledge of some of the areas that are prerequisite... had developed to the point that it was possible for us to have the right concept of what it is all about.

Context: America did not invent human rights. In a very real sense, it is the other way round. Human rights invented America.
Ours was the first nation in the history of the world to be founded explicitly on such an idea.
Context: I have just been talking about forces of potential destruction that mankind has developed, and how we might control them. It is equally important that we remember the beneficial forces that we have evolved over the ages, and how to hold fast to them.
One of those constructive forces is enhancement of individual human freedoms through the strengthening of democracy, and the fight against deprivation, torture, terrorism and the persecution of people throughout the world. The struggle for human rights overrides all differences of color, nation or language.
Those who hunger for freedom, who thirst for human dignity, and who suffer for the sake of justice — they are the patriots of this cause.
I believe with all my heart that America must always stand for these basic human rights — at home and abroad. That is both our history and our destiny.
America did not invent human rights. In a very real sense, it is the other way round. Human rights invented America.
Ours was the first nation in the history of the world to be founded explicitly on such an idea. Our social and political progress has been based on one fundamental principle — the value and importance of the individual. The fundamental force that unites us is not kinship or place of origin or religious preference. The love of liberty is a common blood that flows in our American veins.
