“There’s a fascinating frailty of the human mind that psychologists know all about, called “argument from ignorance.” This is how it goes. Remember what the “U” stands for in “UFO”? You see lights flashing in the sky. You’ve never seen anything like this before and don’t understand what it is. You say, “It’s a UFO!” The “U” stands for “unidentified.”But then you say, “I don’t know what it is; it must be aliens from outer space, visiting from another planet.” The issue here is that if you don’t know what something is, your interpretation of it should stop immediately. You don’t then say it must be X or Y or Z. That’s argument from ignorance. It’s common. I’m not blaming anybody; it may relate to our burning need to manufacture answers because we feel uncomfortable about being steeped in ignorance.”

“When asked about which scientist he'd like to meet, Neil deGrasse Tyson said, "Isaac Newton. No question about it. The smartest person ever to walk the face of this earth. The man was connected to the universe in spooky ways. He discovered the laws of motion, the laws of gravity, the laws of optics. Then he turned 26.”

“The problem, often not discovered until late in life, is that when you look for things in life like love, meaning, motivation, it implies they are sitting behind a tree or under a rock. The most successful people in life recognize, that in life they create their own love, they manufacture their own meaning, they generate their own motivation. For me, I am driven by two main philosophies, know more today about the world than I knew yesterday. And lessen the suffering of others. You'd be surprised how far that gets you.”

“To make any future that we dreamt up real requires creative scientists, engineers, and technologists to make it happen. If people are not within your midst who dream about tomorrow - with the capacity to bring tomorrow into the present - then the country might as well just recede back into the cave because that's where we're headed.”

“You can't have people making decisions about the future of the world who are scientifically illiterate. That's a recipe for disaster. And I don't mean just whether a politician is scientifically literate, but people who vote politicians into office.”

“I think the greatest of people that have ever been in society, they were never versions of someone else. They were themselves.”

“We live in the kind of society where, in almost all cases, hard work is rewarded.”

“I think the greatest of people in society carved niches that represented the unique expression of their combinations of talents, and if everyone had the luxury of expressing the unique combinations of talents in this world, our society would be transformed overnight.”

“The universe is almost 14 billion years old, and, wow! Life had no problem starting here on Earth! I think it would be inexcusably egocentric of us to suggest that we're alone in the universe.”

“Passion is what gets you through the hardest times that might otherwise make strong men weak, or make you give up.”

“We explore our environment, more than we are compelled to utter poetry, when we're toddlers. We start doing that later. Before that happens, every child is a scientist.”
