Leonardo da Vinci did not take received wisdom - whether from ancient classical thinkers or medieval scholars or from the Bible - without questioning it. And this was the beginning of the scientific method. This is another lesson for our time: that when we have evidence that contradicts a certain belief, we should be willing to change it. I think this made Leonardo, in some ways, a person who better understood the beauty of God's creation than a person who just takes all received wisdom from the Bible on faith.

I think when money starts to corrupt journalism, it undermines the journalism, and it undermines the credibility of the product, and you end up not succeeding.

I think that we shouldn't be fixated all the time on the ups and downs of the weekly ratings, of the quarter-hour ratings.

Smart people are a dime a dozen. What matters is the ability to think different... to think out of the box.

Leonardo da Vinci was comfortable being illegitimate, gay, a misfit, a heretic. But he also respected other people. He didn't get into disputations. He was a genius but he had a certain humility. In his notebooks you see lists of people he wanted to grill about things like how the water diversions in Milan work; he was always interested in learning from other people.

More generally, I made an effort to leave out things that weren't relevant to the main narrative themes of the book, namely that there were two sides to Steve Jobs: the romantic, poetic, countercultural rebel on one side, and the serious businessperson on the other.

We relate to Leonardo da Vinci because his genius was just being passionately curious about everything. He wanted to know everything he could know about our universe, including how we fit into it. We can't all have a superhuman intellect like Albert Einstein's, but we can be super-curious. And we can also quit smashing curiosity out of the hands our children.
