Robotson Crusoe–or–What Is Common Sense?

I will present a perspective on human-level commonsense behavior (HLCSB) that differs from commonsense reasoning (CSR) as the latter is often characterized in AI. I will argue that HLCSB is not far beyond the reach of current technology, and that it also provides solutions to some of the problems that plague CSR, most notably the brittleness problem. A key is the judicious use of metacognitive monitoring and control, especially in the area of automated learning.
