This past weekend, Prince Nikolaus was in Granada to attend the inaugural conference for the Institute of Philosophy Edith Stein, which is a sister organization to the Liechtenstein-based International Academy of Philosophy. The conference, entitled "Realist Phenomenology: Josef Seifert and the Christian Tradition" celebrated the 70th birthday of Austrian-born philosopher Josef Seifert, who has been a friend of Prince Nikolaus for several decades, as well as a friend of the late Pope John Paul II.
The Congress, held at the Granada Diocesan Seminary, was opened by Mons. Javier Martinez, the Archbishop of Granada, and also featured the announced donation of a private library to the institute.
