Let's make this birthday one to remember.

89 years old (Born on June 30, 1935)

Happy Birthday, Professor Achinstein! Another year wiser, and yet philosophers still debate whether your brilliance is innate or acquired. Your groundbreaking insights at Yeshiva University have left students and colleagues alike pondering life's deepest questions—like how you manage to make epistemology sound cooler than rock music.

From your celebrated lectures to your influential writings, you've proven that philosophy isn't just about asking tough questions; it's also about having the wit to answer them with style. May this birthday bring you as much joy as you've brought clarity (and occasional confusion) to generations of thinkers. Cheers to another year of philosophical adventures!
