Education, and I regret to say this as an educator, but there's no indication that education has a direct effect on happiness.

As countries embrace mass higher education, the cost of maintaining universities increases dramatically relative to an elite system.

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.

An educated man must have a "curiosity in exploring the unfamiliar and unexpected, an open-mindedness in entertaining opposing points of view, tolerance for the ambiguity that surrounds so many important issues, and a willingness to make the best decisions he can in the face of uncertainty and doubt".

The college that takes students with modest entering abilities and improves their abilities substantially contributes more than the school that takes very bright students and helps them develop only modestly.

Ever since economists revealed how much universities contribute to economic growth, politicians have paid close attention to higher education.

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.
