The idea here is that true command requires personal self-governance; someone who cannot take care of themselves lacks the discipline and judgment needed to lead others. This notion is attributed to William Penn, who emphasized personal virtue and self-control as foundations for responsible governance. In leadership terms, a commander must demonstrate self-discipline and reliability before exercising authority over subordinates and missions. The other figures are known for different areas—air power theory, battlefield leadership, or Civil War reforms—so they don’t align with this specific statement. That makes William Penn the best fit.
