W. D. Ross was already known for his scholarly editions of Aristotle when he published his own lasting contribution to philosophy in 1930. The Right and the Good proposed an ethical theory not based on absolute rules or merely on scoring results of one’s actions, but on weighing certain intuitively known “prima facie” duties. In 38 days, the right of the US public to freely copy and reuse Ross’s book will legally outweigh any duty to keep it proprietary. #PublicDomainDayCountdown
