In Csikszentmihalyi's book "Creativity", pg 119, Barry Commoner is quoted: > I write with this pen [he removes a fountain pen from his breast pocket and holds it up]. And it’s very clear to me that my ability to think and write at the same time depends on the flow of ink. The thing I enjoy most is the flow of my own ideas and getting them down on paper. I will not write with a ballpoint pen, because it doesn’t really flow. That’s why I use a fountain pen. And only a fountain pen that really works very well.
