Any opportunity to revisit the wisdom of Rabbi Dr. Abraham Joshua Heschel of blessed memory is an opportunity to be relished.
Dr. Heschel made a deep impact upon my life in my most formative years, as an undergraduate student. On two occasions, I got to hear him, first in a three lecture series at a Catholic university and once at a university student convention. Even after several decades I can still remember much of what he said and the way that he said it.
I was certain that I could not have enough of his fantastic wisdom so impressively and authentically imparted. I rushed out to purchase his books and they became my constant companions.
Every Shabbat on campus, largely observed all alone, I would read Heschel’s magnificent essay in book form with woodcut illustrations, The Sabbath: Its Meaning for Modern Man. This was my entrance each week on campus to Heschel’s concept of the Sabbath as a Sanctuary in Time.
In later years, I could boast of personal contact with Dr. Heschel and ownership of numerous autographed editions of his dozens of life changing books.
The Prophets, God in Search of Man, Insecurity of Freedom and Man Is Not Alone are a few of my favorites, but there are so many other pearls. Professor Fritz Rothschild published a wonderful compilation of Heschel’s writings still available, that I highly recommend, Between God and Man.
Heschel’s daughter Susannah Heschel published her own edited work of his writings, Abraham Joshua Heschel: Essential Writings.
Your original question explaining, “Wonder rather than doubt is the root of knowledge” is to be seen in the context of Heschel’s concept of radical amazement. The quote comes from his book, Man Is Not Alone.
Dr. Heschel could not abide complacency. A human must live in a state of amazement at the magnificence of God and God’s creation. In Heschel’s day doubt became the popular byword of theologians. Heschel wished to turn theological inquiry from doubt to wonder.
In Man Is Not Alone Heschel teaches us how to approach the task at hand, he writes, “The greatest hindrance to knowledge is our adjustment to conventional notions, to mental clichés. Wonder or radical amazement, the state of maladjustment to words and notions, is, therefore, a prerequisite for an authentic awareness of that which is.”
“Standing eye to eye with being as being, we realize that we are able to look at the world with two faculties — with reason and with wonder. Through the first we try to explain or to adapt the world to our concepts, through the second we seek to adapt our minds to the world.”
It should be obvious that Heschel within four years of arriving in America from Europe became a master of the English language and devoted himself to the creation of an experience through words. This is seen in his work, The Earth is the Lord’s.
Let me add that in Jewish tradition our daily prayers found in the Siddur—Jewish prayer book reflect Heschel’s wonder and radical amazement by offering a series of berakhot (blessings) acknowledging God’s beneficence in our lives each morning for the natural activities of humankind such as awakening, sight, stepping on solid ground or wearing clothing. These acts are all too often taken for granted.
The Jew is called upon to not take anything for granted. We must live our lives in wonder and radical amazement. This is indeed a tall order.
Let us end with a further quotation of Heschel on wonder. "Wonder goes beyond knowledge. We do not doubt that we doubt, but we are amazed at our ability to doubt, amazed at our ability to wonder. … We are amazed at seeing anything at all, amazed not only at particular values and things but at the unexpectedness of being as such, at the fact that there is being at all.”
