Dear, Chuck, Ken, Keith et al,
Deduction from experience:
I suggest that a simple example of the presence of deduction in design
thinking occurs along with the abductive projection of possible design
developmental paths to follow when one deduces that one path is probably the
more productive based on past experiences in similar design situations.
