In page Shirley M. Tilghman:

"

For Tilghman, Princeton has two essential missions. "One is to ensure that our doors are open as wide as possible to every talented student in the world who is capable of doing the hard work we ask of them.[citation needed] And that means maintaining our commitment to financial aid, which is the tool – the critical tool – to get those students to Princeton. And the second thing is that we must address the most critical issues, and push back the frontiers of knowledge, and not just in science and technology, but in social policy, and in public policy, and in understanding the nature of the human condition."[2]
