Great debates in Jewish History

 Imagine that you were able to rethink everything you knew about the universe, the laws of nature, your own consciousness, and the very idea of existence and reality. Imagine the new insights you will gain, the fresh perspective with which you will embark on the journey of life each morning.

What is? does exactly that. Drawing on the wisdom of Chassidic teaching, the most basic building blocks of existence are reexamined from the bottom up, revolutionizing our understanding of life, reality, and our place in the world.

Lesson One: Is the World Real?
Everything that we experience, we experience inside our heads, leading to the intriguing question: Maybe there is no existence outside of our minds? But perhaps a more fundamental question would be: What practical difference does it make if the world is real or not?


Lesson Two: Is Time Travel Possible?
Is time the engine that drives the whole of existence, or is it just a product of our subjective experience? If the future is impenetrable, the past irretrievable, and the present moment too fleeting to meaningfully inhabit, what part of our lives can we call our own?


Lesson Three:Why does evil exist?
Why do bad things happen to good people? The question has been asked—and answered—for thousands of years. But even if we understood the purpose of evil, would this make it more palatable and acceptable? Would it aid us in our efforts to defeat evil?


Lesson Four:Who is G‑d?
What are we talking about when we talk about G‑d? Is “G‑d” just a word we use when we can’t explain something? If G‑d cannot be explained or described, does this not render the concept of “belief in G‑d” completely meaningless?


Lesson Five:What is consciousness?
All injustice and strife, and even personal unhappiness, can be traced to selfishness. Yet self-esteem is essential for a healthy psyche and a productive life. To navigate this paradox, we first need to unravel the mystery of self-awareness: Where does our sense of self come from?


Lesson Six: Are we bound by fate?
If G‑d already knows what we will do tomorrow, is our “free choice” nothing more than an illusion? And with so many powerful influences outside of our control—or even our awareness—influencing our choices, how “free” could they possibly be?
