Social media and the Internet haven't changed our capacity for social interaction any more than the Internet has changed our ability to be in love or our basic propensity to violence, because those are such fundamental human attributes.

It is well to look around at whom, and not just what, surrounds us. Population structure will change everything. Our health, wealth, and peace depend on it.

My entire youth was spent with an incredibly ill parent... I don't think you can grow up that way and not be marked by that experience.

I like to have met someone in real life before being their Facebook friend.

Not ignorance, but ignorance of ignorance, is the death of knowledge.

Social media reactions to celebrity death have taken on a predictable pattern: an outpouring of shock with expressions of grief, followed by a ghoulish need to know all the details, to see the scene of the death and the family in mourning. Then a post-mortem dissection of all the perceived flaws the celebrity had.

I'm used to being in front of camera and knowing what to think. But if you're asking me to be me, I get very self-conscious. My job isn't to be me. Being an actor, people think you can do a eulogy at a funeral, a speech at a wedding. I find all that very nerve-racking.

It is bitter to lose a friend to evil, before one loses him to death.
