Dario Cabanelas Rodríguez, born in Trasalba, Ourense, Spain, December 20, 1916, and died there, September 18, 1992, may be considered one of the most important Spanish Arabists of the 20th century.  After studying baccalaureate, philosophy and theology in Santiago de Compostela, he was ordained as a priest into the Franciscan Religious Order in June 23, 1940.  Since 1942, he studied philosophy and humanities, Section of Semitic Philology, at Central University, called today Complutense University, in Madrid, with Extraordinary Degree Award, and he got the doctorate in June 15, 1948, about the topic "Juan de Segovia y el problema islámico", with a Special Award Doctorate.  He was a holder of a scholarship and a collaborator at Miguel Asin Palacios Institute of Spanish National Research Council.  He taught Arabic language and literature at the Complutense University of Madrid and from 1955 was Professor at the University of Granada.  He was a disciple of Emilio Garcia Gomez, he trained a lot of professionals during four generations for more than forty years.  His scientific contributions are very extensive: he wrote over 100 works, among books, articles, bibliographical reviews and reports, as well as being director of 18 doctorates, 26 master dissertations, etcetera, and lectured on the Arab and Islamic world in Spain and abroad.  He specialized mainly in Arabic linguistics, literature and philosophy, and among his most outstanding works are his writings on Ibn Sida and Alonso del Castillo.  Furthermore, he occupied high academic places and dignities, such as Dean of the Faculty of Philosophy and Humanities in Granada (1965-1968), Director of Department of Arabic in Granada (1972-1987), Director of the School of Arabic Studies of Spanish National Research Council in Granada (1972-1984), Membership of Royal Academy of Fine Arts in Granada (1977-1992), President of Alhambra and Generalife Council's Publications Commission (1978-1985), Membership "al honorem" of Institute for Cooperation with the Arab World of the Foreign Office in Spain (1979-1992) and others.

He practised psychiatry in Italy until 1939, before moving with his family to the United States.  There he became fascinated by Freud’s theory, in which he rooted all the features of his own thinking.  He did not want to create a new psychoanalytic terminology, but, although he used Freud’s terms, he gave them radically new meanings. Loewald's father, who died shortly after his birth, was a Jewish physician with an interest in dermatology and psychiatry; his mother a gifted musician, who played the piano. <SEP> Martin Heidegger ( ; ] ; 26 September 188926 May 1976) was a German philosopher and a seminal thinker in the Continental tradition and philosophical hermeneutics.  According to the "Internet Encyclopedia of Philosophy", he is "widely acknowledged to be one of the most original and important philosophers of the 20th century".  Heidegger is best known for his contributions to phenomenology and existentialism, though as the "Stanford Encyclopedia of Philosophy" cautions, "his thinking should be identified as part of such philosophical movements only with extreme care and qualification". <SEP> Hans Zollner is a German theologian and psychologist.  He has been a member of the Jesuits since 1990.  He studied philosophy and theology in Regensburg and Innsbruck.  Since 2003, he has taught at the Institute of Psychology at the Pontifical Gregorian University in Rome.  Zollner has been the academic Vice Rector of the Gregorian since 2010.
