What I Have Not Learned

As I approach retirement and reflect on nearly 80 years of life and over 50 years as an educator, I am struck by a humbling realization: the more I learn, the less I seem to know. Influenced by Wittgenstein’s Tractatus Logico-Philosophicus and its final proposition—“Whereof one cannot speak, thereof one must remain silent”—I have come to appreciate the limits of knowledge and the importance of humility in scholarship and life. My career, though unplanned, has taken me across diverse roles in philosophy, computer science, and instructional systems, yet the most profound lesson came not from academic achievements but from the realization that knowledge alone is insufficient without care for others. Echoing my professor’s advice to think for oneself but live for others, I have grown to believe that the true purpose of education extends beyond skill acquisition; it lies in fostering compassion, intellectual humility, and meaningful contributions to humanity. I lament that I may have done too little to instill these ideals but hope that my students will surpass me in advancing lives centered on peace, service, and community. Ultimately, as my father once said, what remains is not what you say but what you do, and it is my earnest desire that education continues to inspire action toward the betterment of others.
