Some of you will recall that I'm reading the 10-volume Encyclopedia of Philosophy (second edition) at the rate of two pages per day. I've been at it since 24 April 2007. Today I finished the letter "U." Among the entries I've read are:

Ugliness
Ulrich (Engelbert) of Strasbourg
Unamuno y Jugo, Miguel de
Unconscious
Underdetermination Thesis, Duhem-Quine Thesis
Unity and Disunity of Science
Universal Properties in Indian Philosophical Traditions
Universals, A Historical Survey
Utilitarianism
Utopias and Utopianism

I read the two pages first thing in the morning. It takes about 15 minutes.
