“Every intellectual has a very special responsibility. He has the privilege and the opportunity of studying.”

We must plan for freedom, and not only for security, if for no other reason than only freedom can make security more secure.

“It can’t happen here” is always wrong: a dictatorship can happen anywhere.

Economic growth without social progress lets the great majority of the people remain in poverty, while a privileged few reap the benefits of rising abundance.

The pain that you hold is yours. This pain is not your curse; this pain is your privilege.

Life is a gift, and it offers us the privilege, opportunity, and responsibility to give something back by becoming more.

The privilege of a lifetime is to become who you truly are.

Think for yourself and let others enjoy the privilege of doing so too.
