Andrew Tuck sits in a stylish loft in New York City's Soho neighborhood with some of his life's work spread before him. There's his philosophy book, published by a top-drawer academic press, which he wrote in the 1980s while working at his day job: teaching students at Columbia University. Then there's his recording of some jazz tunes that he composed while he worked as a musician at night during the same period. "I was living my undergraduate dream," says Tuck, now 47. "I was teaching at an Ivy League institution and working with well-known musicians."
