“This is just my way of pointing out that we people who leap without looking are not stupid. We know damn well we might be headed for a fall. But we also know that, sometimes, it's the only way out.”

“our world requires that decisions be sourced and footnoted, and if we say how we feel, we must also be prepared to elaborate on why we feel that way...We need to respect the fact that it is possible to know without knowing why we know and accept that - sometimes - we're better off that way.”

“Most times we only see things for the way we are. But we're good at lying to ourselves. Sometimes we need somebody who's not living in our skin to point out how things really are.”

“When we gaze at a star in the Milky Way which is 50,000 light-years away from our sun, we are looking back 50,000 years in time.""The idea is much too big for my little head.""The only way we can look out into space, then, is to look back in time. We can never know what the universe is like now. We only know what it was like then. When we look up at a star that is thousands of light-years away, we are really traveling thousands of years back in the history of space.”

“We don't always have a choice how we get to know one another. Sometimes, people fall into our lives cleanly--as if out of the sky, or as if there were a direct flight from Heaven to Earth--the same sudden way we lose people, who once seemed they would always be part of our lives”

“The biggest mistake we can make is to think that we've figured the whole thing out. The people I know who are the greatest skeptics, who are least certain about how the world and the universe works, are also the most intelligent.... Absolute certainty is only for stupid people. It requires a certain intelligence for us to realize how little we actually know.”
