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.

Leonardo da Vinci was lucky to be born the same year that Johannes Gutenberg opened his printing shop. As a young person, he could get information about whatever struck his curiosity. The Internet is to our age what Gutenberg's press was to his, so he would have loved being alive today.

If you want to live your life in a creative way, as an artist, you have to not look back too much. You have to be willing to take whatever you’ve done and whoever you were and throw them away. The more the outside world tries to reinforce an image of you, the harder it is to continue to be an artist, which is why a lot of times, artists have to say, “Bye. I have to go. I’m going crazy and I’m getting out of here.” And they go and hibernate somewhere. Maybe later they re-emerge a little differently. (Steve Jobs)

I think the biggest innovations of the twenty-first century will be the intersection of biology and technology. A new era is beginning, just like the digital one was when I was his age.

I used to be an angry man myself. I’m a recovering assaholic so I could recognize that in Steve. (quoting Jean-Louis Gassée)

What Einstein was able to do was - to use a cliche - think out of the box.
