Good thought, but Abraham Isaac Kook was a proponent of a religious national philosophy. Rav Kook was appointed the first Chief Rabbi of Israel. He tried to broaden the outlook of the yeshivot to cope with modern ideas and train spiritual leaders. His mystical leanings helped him embrace even the non-religious pioneers and earned him the respect of the entire Zionist world. Rav Kook set up his own Yeshiva, which later became known as Mercaz Harav. He was an outspoken critic of the British Mandatory government and a staunch defender of the Revisionist Movement during the infamous Arlozoroff affair, once he became convinced of their innocence. His many works in philosophy and halacha include "Iggeret Hareaya", "Orot Hateshuva", "Shabbat Haaretz", "Daat Kohen" and "Mishpat Kohen" .
