An artist and a scientist or engineer of the highest calibre differ little: both express something of the truth they perceive so that others can benefit.

I actually think there's actually very little distinction between an artist and a scientist or engineer of the highest calibre. I've never had a distinction in my mind between those two types of people. They've just been to me people who pursue different paths but basically kind of headed to the same goal which is to express something of what they perceive to be the truth around them so that others can benefit by it.
