I've enrolled in my first online course: The Architectural Imagination, offered by the Harvard Graduate School of Design. I completed the first module, The Architectural Imagination: An Introduction. Like any college course, there are lectures, readings, and assignments. The opening lecture establishes the difference between a mere building and a work of architecture. The first instructor, K. Michael Hays, starts with Kant, which is good, then moves on to Gilles Deleuze. I had forgotten how opaque Deleuze could be. The first assignment was to analyze two structures and identify what makes them architectural. I will post my response to the assignment next.
Next up in the course is module two, Reading Architecture: Column and Wall. I'll post my responses to that module in the near future.
