Rabbi Zadok ha-Kohen Rabinowitz of Lublin , or Tzadok Hakohen or Tzadok of Lublin, was a significant Jewish thinker and Hasidic leader.
Biography
He was born into a Lithuanian Rabbinic family and then became a follower of the Hasidic Rebbe, Rabbi Mordechai Yosef Leiner of Izbica, and of Yehudah Leib Eiger, whom he succeeded in 1888. He is a classic example of a Litvish Jew turned Chasidic. As a young man he gained widespread acclaim as an . Rabbi Zadok refused to accept any rabbinic post for most of his life. He eked out a living by his wife running a small used clothing store. Upon the death of Eiger in 1888, Zadok Hakohen agreed to take over the leadership of the Hasidim. It was then that he began to give his public classes that would take place on Shabbat, Holidays, Rosh Chodesh and special occasions. The transcriptions of those classes were compiled into his work known as Pri Tzadik. Rabbi Zadok was a prolific writer in all areas of Judaism, halakhah, Hasidut, Kabbalah, angelology, and ethics; he also wrote scholarly essays on astronomy, geometry, and algebra. One of his lone surviving students was Rabbi Michael Mokotovsky, whose son was Rabbi Avraham Eliyahu Mokotovsky, better known by his penname Eliyahu Kitov.
Ideas
Zadok HaKohen's radical philosophy of Judaism very much continues the thinking of his teacher Rabbi Mordechai Yosef Leiner. Zadok HaKohen was much more of a prolific writer than Leiner ever was. It is therefore difficult to determine where Rabbi Zadok's radicalism is a mere articulation of ideas left somewhat veiled in the writings of Leiner and where Rabbi Zadok is actually breaking new ground.
Tzidkas HaTzaddik
You can learn a lot about a person from his dreams. What we dream is a reflection of who we are. It is the measure of our aspirations and goals, and of those values we hold dear and place above all else. One does not squelch the evil inclination but rather helps channel its energies positively.
Pri Tzaddik, Genesis
Humanity's first sin was not Adam and Eve's eating of forbidden fruit, but rather the way they ate it. The Tree of Knowledge, says he, was not a tree or a food or a thing at all. Rather it was a way of eating. Whenever a person grabs self-conscious pleasure from the world, he falls, at that moment, from God consciousness, and eats from the Tree of Knowledge.
Takkanas HaShavim
Zadok HaKohen said that the Oral Law developed to its full potential after the victory of the Hasmoneans over the Greek culture, a culture characterized by deep analysis and hair-splitting argument. These virtues were converted to a holy nature with the victory of Israel over Greece. This was the fulfillment of the verse “God will give beauty to Yefet and this beauty will dwell in the tents of Shem”. After the victory, Jews could begin the successful integration of natural science, logic and philosophy into the world of the Written Law. Only then could the Oral Law truly begin to flourish.
Influence
Zadok HaKohen's philosophy was a major influence on Rabbi Yitzchok Hutner. Rabbi Moshe Tuvia Lieff has given numerous lectures on the works of Zadok HaKohen.
