Two casts of mind

“No two things could be more directly opposite than the cast of mind of the logician and that of the mathematician”

Charles Sanders Peirce

An engineer and an artist

“It’s the only job I can think of where I get to be both an engineer and an artist. There’s an incredible, rigorous, technical element to it, which I like because you have to do very precise thinking. On the other hand, it has a wildly creative side where the boundaries of imagination are the only real limitation.” Andy Hertzfeld

"It’s chilling to recall how this cast of young and inexperienced people who cared more than anything about doing great things created what is perhaps the key technology of our lives. Their own words and images take me back to those rare days when the rules of innovation were guided by internal rewards, and not by money." Steve Wozniak
