Cook applied to Duke University for business school. While there he took an ethics class that he says profoundly impacted him.
As he embarked on his career, and in particular as he began work at Apple in the late 1990s, Cook realized that the most sophisticated developments have equal parts technical and human elements.
"For Apple, we believe strongly that the most important things in life stand at the intersection of technology and the liberal arts," Cook said. "It's the intersection of those things that you can do really profound things for people that really enriches their lives. And so I think, for me at least, it was important to have a broad view of both."
Since finishing his formal schooling, Cook said he continues educating himself and particularly values learning about art and music.
