Wisdom For The Future
Illustration
by G. K. C. MacDonald

William Thomson (later Lord Kelvin) was one of the greatest physicists of nineteenth-century England. When he was away at college, his father wrote to him: “You are young: take care you be not led to what is wrong. A false step now, or the acquiring of an improper habit, might ruin you for life. Frequently look back on your conduct and thence learn wisdom for the future.”
