It is good to know where you came from. It is even better to know where you’re going. (Antonin Scalia, late justice of the U.S. Supreme Court)
Scalia’s comments in a commencement address are most appropriate for graduates who are excited about having completed their course of study, but who face an unknown future. The future is the focus of graduation exercises, hence the name commencement, which means beginning. The value of what has been learned is limited if you don’t know where you’re headed.
For the wise can see where they are going, but fools walk in the dark. (Ecclesiastes 2:14)
