through a kind of dream consciousness."
—Richard Kearney, quoted here yesterday afternoon
"You make me feel like I'm living a teenage dream."

Quoted here last year on this date—
Alexandre Borovik's Mathematics Under the Microscope (American Mathematical Society, 2010)—
"Once I mentioned to Gelfand that I read his Functions and Graphs ; in response, he rather sceptically asked me what I had learned from the book. He was delighted to hear my answer: 'The general principle of always looking at the simplest possible example.'….
So, let us look at the principle in more detail:
Always test a mathematical theory on the simplest possible example…
This is a banality, of course. Everyone knows it; therefore, almost no one follows it."
