Rabbi Natan Margalit

In this series of classes we will look at new perspectives on how core Jewish ideas, and ways of thinking can deepen and reinforce our work for justice, sustainability and health.  By helping to  shift our orientation toward dynamic relationships, getting beyond either/or traps and visioning hope and freedom instead of despair and gridlock, Jewish wisdom can help us become better at creating the change we want to see-- in ourselves and in the world.  We will use text study, discussion and experiential exercises.  

Six Classes:

Organic Torah Principles of Sustainability: Emergence/Minyan – The whole is greater than the sum of the parts: 

The natural world emerges through relationships of networks, patterns and systems – the whole is always greater than the sum of the parts. Judaism has also been built on this natural principle. The minyan is only one example. We’ll see how Judaism and the natural world connect through the principle of emergence which allows for flexible growth, newness and strength. In practical terms, new and just solutions to social problems only emerge when we look at the whole and the part that everyone plays in creating it.     

Organic Torah Principles of Sustainability: Nestedness/Mikdash – fractal reality and getting past either/or

Nestedness is the way of the natural world: cells are nested inside organs, inside bodies, inside families, etc.  In Judaism mikdash – the sacred holy center, is nested within the inner chamber, within outer walls, within the city gates, etc. We’ll see how this principle allows for both/and solutions instead of false either/or dilemmas.   

Organic Torah Principles of Sustainability: Tipping Points/Mitzvah – Hope, faith and free will: how not to give up. 

In natural systems change isn’t linear, but can jump suddenly from one state to another: the straw can break the camel’s back.  Judaism also embraces this principle as we see in the spiritual technology of the mitzvah: doing a small action which may just change everything – but we never know.  In ecological work we must know that a small action can have huge consequences – both for bad or for good.

Applying Organic Torah: The Ethics of Eating and Agriculture

We will look at how Judaism supports an ethical and sustainable agriculture through changing our perspective to one of gratitude, caring and stewardship.

Applying Organic Torah: Environment and Climate Change

We will see how Jewish principles can give us the tools to shift our attitudes and behavior in battling the crisis of climate change.

Applying Organic Torah: Prayer, Holidays and Social Justice

In this class we will explore the way that the Jewish holiday and prayer cycles support a consciousness of justice and sustainability.

The Radical, Reasonable Route To 80% Reductions

Speaker: Fred Davis

Many in Massachusetts don't realize we’ve been leading the country in conservation and renewables. This updated presentation demonstrates the path to dramatically reduce our use of energy at each level: world, national, state, synagogue, residence. Drilling down from the global to the granular, we appreciate that the process is the same: assess (benchmark), plan, and implement changes over time. It is not beyond us.

Fred Davis, JCAN Vice president pro-tem, has been professionally involved with energy conservation since 1977, starting in residential conservation and solar, and helped devise the first national standards for lamp efficiency. He is president of Fred Davis Corporation, a leading national wholesale supplier of energy-efficient lighting products since 1983. He chaired the first national conference on energy-efficient lighting and has spoken on energy and lighting from Stockholm to Sacramento. Fred was President of the Urban Solar Energy Association, has served on the Board of Northeast Sustainable Energy Association, and on both national and local Boards of the Illuminating Engineering Society of North America. He is a past Co-Chair of the JCRC Energy Committee, and a Past President of the Jewish Genealogical Society of Greater Boston.

Extracting Fossil Fuels from Your Portfolio

Speaker: David Schreiber

As Jews we are obligated to practice tikkun olam and do what we can to repair the world, and also to pursue justice. This workshop is focused on the why, how and what of obtaining comparable returns through carefully designed and balanced portfolios of securities screened for the environmental, social and governance practices of the companies behind them. It is designed to help both individuals and institutions move to fossil-free investments.
