“I’m an idealist without illusions.”

2014, Statement on Cuban policy (December 2014)
Context: I’m under no illusion about the continued barriers to freedom that remain for ordinary Cubans. The United States believes that no Cubans should face harassment or arrest or beatings simply because they’re exercising a universal right to have their voices heard, and we will continue to support civil society there. While Cuba has made reforms to gradually open up its economy, we continue to believe that Cuban workers should be free to form unions, just as their citizens should be free to participate in the political process.
Moreover, given Cuba’s history, I expect it will continue to pursue foreign policies that will at times be sharply at odds with American interests. I do not expect the changes I am announcing today to bring about a transformation of Cuban society overnight. But I am convinced that through a policy of engagement, we can more effectively stand up for our values and help the Cuban people help themselves as they move into the 21st century.

Context: The last level of metaphor in the Alice books is this: that life, viewed rationally and without illusion, appears to be a nonsense tale told by an idiot mathematician. At the heart of things science finds only a mad, never-ending quadrille of Mock Turtle Waves and Gryphon Particles. For a moment the waves and particles dance in grotesque, inconceivably complex patterns capable of reflecting on their own absurdity.
