Doctoral training is devoted almost entirely to learning to do research, even though most Ph.Ds who enter academic life spend far more time teaching than they do conducting experiments or writing books.

For some students, especially in the sciences, the knowledge gained in college may be directly relevant to graduate study. For almost all students, a liberal arts education works in subtle ways to create a web of knowledge that will illumine problems and enlighten judgment on innumerable occasions in later life.

If you think education is expensive, try ignorance.
