• Mordecai M. Kaplan (1881-1983) was one of the most influential Jewish thinkers of the 20th century.  We believe that his thought may be even more important in the 21st century.

  • "Reconstructionism is a method, rather than a series of affirmations or conclusions concerning Jewish life or thought. ... Reconstructionism is not the ideas about God, ritual, community ... which anyone may hold. It is a method of dealing with Judaism, or with that which unites Jews in time and space, and differentiates them as a group from non-Jews."  -- Mordecai M. Kaplan, Questions Jews Ask (1956), pp. 80-81.

"Kaplan on Creation, Creativity, and Us"

Kaplan is much undervalued as a theologian.  We think of him as a sociological thinker, with his central concept of “Judaism as a Civilization.”  But, of course, he is much more than that.  We might refer to him as the sociologist become theologian.  Below we will see the theologian at work.

Kaplan understands that when we talk of creation we mean to refer to the order and unity that comes out of the chaos – out of the Tohu va-Vohu as the Torah puts it.  (I love this expression, not the chaos but the words, because there is so much chaos in my life and in the world that I need to remove.)  The order and the unity that are the primary qualities of creation may be found not only in the outer universe but also in the inner life of each of us.  The inner life is always a reflection of the larger cosmos.  We are connected.  Thus, whenever we create, we are in a sense contributing to the greater order and unity that is the ongoing process of creation. Our creative acts are a manifestation of the Divine. ...

From the Executive Director

Why a Kaplan Center?

More than 80 years ago, at the very beginning of the very first issue of The Reconstructionist journal, Rabbi Mordecai M. Kaplan and his colleagues reprinted an editorial from a 1928 issue of that journal’s predecessor, The S.A.J. Review, succinctly explaining their reasons for the creation of a new movement. “[T]he problem of Jewish life is just th[e] problem of unity,” the editorial stated. “A solution to the problem of Jewish life depends upon finding, or making, a positive ideology which will enable both Orthodox and Reform, both believers and nonbelievers, to meet in common and to work together. It is only by conceiving Judaism as a civilization, and not as a general religious movement embracing many sects, that we will be able to construct such an ideology and reconstruct the Jewish civilization." ...

The Kaplan Conversations

We are happy to offer you a new venture from the Kaplan Center.  Each month, we will present a selection from the recently published Communings of the Spirit – The Journals of Mordecai M. Kaplan, Volume 2: 1934–1941, edited by Mel Scult.  We invite you to react to Kaplan’s often radical ideas, to his daily struggles with himself, and to his entanglements with the Jewish community.  We will then put up some of the responses on our website.

So come and join the conversation by clicking here.


 For the Cognoscenti: The Kaplan Quiz (Round 8) 

On December 8, 1950, a modern Orthodox rabbi in Pittsburgh named Morris Landes wrote to Rabbi Kaplan to introduce the work that would become Rabbi Landes’ doctoral dissertation at the University of Pittsburgh, an “analysis of the varying conceptions of the mitzvot massiot held by accepted leaders of American Jewish thought in the Reform, Reconstructionist, Conservative, and Orthodox ranks.” Rabbi Landes asked Rabbi Kaplan “to list ten men in the general Conservative ranks and ten among the Reconstructionists, who would be considered accepted leaders of their denominational thought.  It is understood that the same names may appear in both lists. There is no desire here to put you in the difficult position of choosing the ten leaders of your denomination, merely ten representative leaders of denominational thought, whose published works are available, with the understanding that there might be others who might equally appear on this list.”

In a letter dated December 21, 1950, Rabbi Ira Eisenstein replied to Rabbi Landes on behalf of Rabbi Kaplan.  Rabbi Eisenstein wrote that Rabbi Landes’ letter “was discussed by [Rabbi Kaplan] and one or two of us in the Reconstructionist Foundation office, and I am pleased to submit herewith the names of ten Reconstructionists whom you might want to use for your study.  I think that it would be best for you to approach the Rabbinical Assembly of America to get the list of ten Conservative men.”  (Rabbi Eisenstein for some reason did not mention in his letter that he was then the president of the Rabbinical Assembly.)

The list of Reconstructionist thought leaders set out in Rabbi Eisenstein’s letter included Rabbis Kaplan and Eisenstein themselves as well as Rabbis Eugene Kohn, Jack J. Cohen, and Milton Steinberg, who had died a few months earlier.  The other five names on the list are far from obvious. 

Question:  What is the name of one of those other five people on the Reconstructionist list (two of whom were not rabbis)?

If (as we expect) numerous people correctly identify one of those Reconstructionist thought leaders, the tie will be broken in favor of the person who submits the most correct names. Accordingly, you should do your best to submit five names. (Caution:  If you send in more than five names, we will accept the first five and discard the rest.) 

Please send your answers to [email protected].  Once again, the first person to answer correctly wins free admission to a Kaplan Center conference or other event.  The correct answer will be posted in a few days.

Eric's Forum

For the next year, I will be using this space to post selections from the published writings of Mordecai Kaplan that address issues of continued relevance to Jewish (and non-Jewish) life. Most of these will be passages that are not well known. A new selection will be posted every month. 

For each passage chosen, I will provide a brief introduction that places it in its historical context and situates it within the rest of Kaplan’s thought. After each excerpt, I will share my own thoughts on the passage and then invite you to post your own response to it. My hope is that this forum will thereby become a venue for a vibrant discussion of contemporary issues in Jewish life that is in dialogue with the thought of Mordecai Kaplan. Teaching Kaplan at McGill University and elsewhere, I have seen that engaging with Kaplan in this way leads to rich conversations.

This month’s selection is taken from Questions Jews Ask: Reconstructionist Answers. This book was published by the Reconstructionist Press in 1956 and gathers together many of the “Know how to Answer” columns that Kaplan wrote for The Reconstructionist magazine throughout the 1950s. These columns were responses to questions addressed to Kaplan in writing at lectures given in the late 1940s and early 1950s. (Kaplan insisted that audiences submit their questions on note cards because he believed that this both led to clearer questions and encouraged them to formulate their thoughts as a question.) The book divides the columns thematically—Jewish peoplehood, God, ritual etc.—and each section begins with a significant article published in The Reconstructionist that challenged Kaplan’s approach to the subject, followed by the response that Kaplan published at the time. ...

Education Corner

Jeffrey Schein

Reclaiming and Reconstructing Kaplan’s Educational Legacy

The Kaplan Center is excited to be partnering with the Reconstructionist Rabbinical College and the Jewish Reconstructionist Communities to stage a two-act “play” re-envisioning contemporary Jewish education. 

The first act:  A six-session online seminar, titled “Jewish Education for an Evolving World,” beginning January 9, 2018, facilitated by Rabbi Dr. Jeffrey Schein, the Kaplan Center's Senior Education Consultant, and Sue Penn, the Director of Education at University Synagogue in Irvine, California.  The course asks the question, “What Would a Reconstructed Reconstructionist Jewish Education Look Like?”  Educators, rabbis, and lay leaders are invited to reconsider Kaplan’s vision of Jewish education from Judaism as a Civilization, with an eye toward evaluating how his dreams and goals have fared over the 83 years since he articulated this vision in the final chapter of that great book.  

The second act:  The critical questions coming out of the course will engage a think tank of educators participating in the Reconstructionist Movement Convention that will take place in Philadelphia on November 15-18, 2018.

The seminar will take place on Tuesday afternoons, from1:30-3:15 Eastern time, on January 9, 16, 23, and 30 and on February 6 and 13.  More information, as well as a registration link, is available at: https://www.jewishrecon.org/networks/2017/education-evolving-world.
