Sorry, I think I wasn’t as clear as I could have been. I was just trying to comment on how it seemed like Dennet was bringing it back to a question of designer-or-not. I should have just left it alone I guess.
I think maybe believers have a harder time with the “without reference to a designer” part, partially because it is at a point of disagreement between theists and atheists, and partially because the designer question is a given for them. In any case, I’m happy to leave the designer part aside and focus on design in biology.
I am interested, for instance, in how biological motors do what they do and the purpose/function behind the various components. I worked on a project to design a molecular motor with ~90 atoms, the scale difference between that and flagella or FTPase is just amazing.
