Summary: Ayn Rand's philosophy of Objectivism upholds seven major virtues as indispensable to our lives. Yet what of other qualities of character – such as ambition, courage, spontaneity, liveliness, discretion, patience, empathy, and friendliness? Are these virtues, personality traits, or something else? In this 2013 talk at ATLOSCon, I argued that such qualities are best understood as "moral amplifiers," because their moral worth wholly depends how they're used. I explained why people should cultivate such qualities and why they must be put into practice selectively.
