“if the main reason we listen to music in the first place is to hear passion expressed- as i've believed all my life-then what good is this music going to prove to be? what does that say about us? what are we confirming in ourselves by doting on art that is emotionally neutral? and, simultaneously, what in ourselves might we be destroying or at least keeping down?”

“Music does bring people together. It allows us to experience the same emotions. People everywhere are the same in heart and spirit. No matter what language we speak, what color we are, the form of our politics or the expression of our love and our faith, music proves: We are the same.”

“What you said was true. we don't live or love in a vacuum. There are people around us who care about us who would be hurt, maybe destroyed if we let ourselves feel what we might want to feel.”

“I realize that a certain school of thoughtsays that who we are is something we construct for ourselves. We build ourselves out of what we think we remember, what we believe to be true about our life; and the possessions we gather around us are supposedly a part of this, that we are, to some extent what we own.”

“That's what this book is about: other worlds, what awaits us on them, what they tell us about ourselves, and - given the urgent problems our species now faces - whether it makes sense to go. Should we solve those problems first? Or are they a reason to go?”

“but if I've learned anything, it's that we don't know half of what we think we do. And we know ourselves least of all.”
