Finally !!! The New Catholic Encyclopedia, now about thirty-five years old, is available on line ( see link below ). This will be a great boon to philosophers, theologians, scientists, teachers, and ordinary Catholics, other Christians, and doubters/skeptics/agnostics/atheists.
This will especially welcome to those of you who bought a copy of the " Elements of Philosophy " by William A. Wallace, one of my all time favorites. When I got this book, I found that it leaned so heavily on the Catholic Encyclopedia that the only way you could read it was to go to the library where you had access to the New Encyclopedia.
Those unacquainted with Fr. Wallace will find him highly qualified as a Physicist, Philosopher and Theologian. He was a Navy Lieutenant Commander in WW2, serving in the Pacific at the end of the war. He was also one of Editors of the NCE.
I used " Substance " as a topic to give you philosophers a taste of the content.
History of Fr. William A. Wallace O.P. and list of Publications
Fr. Wallace is getting up in years now but still active the last I heard. I hope some of his former students and confrers will chime in and give us any updates/information you have.
