If I were required to guess off-hand, and without collusion with higher minds, what is the bottom cause of the amazing material and intellectual advancement of the last fifty years, I should guess that it was the modern-born and previously non-existent disposition on the part of men to believe that a new idea can have value.
The ideal for me is to mix it up. When I have a writing workshop, I like to have people that are anthropologists and people who are poking around in other fields, I like to have them all in the same workshop, and not worry about genre.
