Happy Birthday, Jaegwon Kim! May your celebrations be as lively and intriguing as your groundbreaking discussions on mental causation. Your brilliant insights into the mind-body problem have left philosophers scratching their heads—and occasionally laughing at themselves—for decades.

From unraveling complex metaphysical puzzles to inspiring countless students with clarity and wit, you've truly mastered the art of making philosophy both profound and entertaining. Here's hoping this birthday brings you joy that transcends mere physical states—though we're still debating how exactly that's possible!

Cheers to another year filled with thoughtful debates, intellectual triumphs, and perhaps finally solving that pesky mind-body conundrum!
