One way that architects determine the livability of a house or office building is through post-occupancy evaluation (Brand 1994, 65-66). Once the new owners have moved in, representatives from the architect, builder, or developer ask a series of questions. Does the roof leak? Is there enough parking? Is the kitchen big enough? Are there enough electrical outlets? Is there room for expansion or reconfiguration to meet changing needs? What do those who live and work in the building like and not like about it? Which design features work well, and which don't? What could have been done better? Are the occupants happy or unhappy with the structure?

Such evaluations are rare enough in the building trade, since architectural artistes would rather move on to new challenges than learn from their past mistakes; but they are unknown when it comes to worldviews. What would a philosophical post-occupancy evaluation look like?

When faced with change, it is better to bend before you break. The best buildings learn. So do the best philosophies. It remains to be seen whether Objectivism can be taught to learn.
