Two recent experiences provoked me to reflect on the disparity between what I want to know and how much I actually know. To live at peace with this disparity, I’ve had to develop strategies for dealing with my ignorance without falling into skepticism or dogmatism. I share three of those lessons below.

Two Humbling Experiences

First. My newspaper never arrives before I finish breakfast! For this reason, I keep my Oxford Dictionary of the Christian Church on the dining table. This amazing resource contains 1798 double-column pages and many thousands of entries of relevance to church history. It begins with “Aaron” the brother of Moses and ends with “Zwingli” the Swiss reformer. I learn something new, interesting, and useful every morning. But I am also stung with something I’d rather not think about. Almost every time I read from that huge book I am reminded of my ignorance and my insignificance: the millions of lives lived, experiences had, institutions founded, and systems created.

Second. Recently, a long-time friend with whom I have not spoken in years called to catch up. During the course of our conversation, he asked what I thought of the state of the church in the United States. Perhaps he thought that because I’ve taught theology for 35 years to thousands of students from two generations I would have a grasp on what things had been, how they have changed, and where they stand. After a few lame attempts to say something intelligent, I think I said, “I really don’t know.”

You must understand that I’ve always had a passion to know, to understand my world, the flow of human history and my place in it. As a young person I had questions to which I needed answers. How can you act intelligently in a world you do not understand? So, I read and read. I read the Bible, theology, the history of nations, church history, and philosophy. Hundreds of books and tens of thousands of pages! I found satisfactory answers to some of my questions. But many more remain, and new ones arise almost every day.

The first lesson: know your ignorance. Perhaps I should say “feel” your ignorance, because you cannot know the extent of what you do not know. Speak and act with humility and caution.

Big Picture Theories

Of course, there is no shortage of big picture theories. Theories of society and politics, metaphysical theories, theories of human nature, climate futurology, economic theories, and theological visions. Comprehensive theories give us an illusory feeling of omniscience, of knowing the essential truth of all things. Perhaps that is why we like them. But there is no consensus about which theories are true. For abstract theories paint only the vaguest general outlines of their subject matter. They cannot be verified, for they do not create transparent understanding of why things in all their intricate interrelations are exactly as they are.

Our minds long for simplicity and clarity. Simplicity allows us to see the whole thing at one instant, and clarity gives us confidence that we see things as they truly are. Mathematical knowledge is the paradigm case of simplicity and clarity. Physics is the most mathematical of the natural sciences. But what you gain in certainty and clarity of knowledge you lose in descriptive power. For there is more to nature than quantity, much more! Knowing the basic physical/mathematical laws of matter does not give you the power to describe the actual state of the vast array of different kinds of things we experience in the universe. Such non-mathematical theories as we find in psychology, sociology, economics, and politics must be abstract, simple, and general for us to understand them. Like theories in physics, theories that deal with human behavior, insofar as they are abstract, simple, general, offer little help in understanding why things are the way they are in all their actuality.

The Second lesson: The wise person will avoid mistaking theory for actuality or the model for the thing. Theory never exhaustively explains actuality. Let the model direct your attention to the thing.

First-Hand Experience

We all know the limits of first-hand experience. No individual human being’s experience extends to every place and time. The very purpose of education is to make available to each individual the experiences and insights of countless other individuals from other places and times. It is the distinctive glory of humanity that we are not limited in knowledge and wisdom to our natural instincts or to what we can learn from our own experiences. Still, each individual must integrate information received from diverse sources into a unified whole centered in themselves. We are limited to the information we receive and to our powers of integration; we cannot leap outside of ourselves to get a God’s-eye point of view. Nor can we know how well our limited vision of things corresponds to a universal consciousness.

Though we must acknowledge the limits of our knowledge, few of us can believe that one individual’s vision of the world bears no resemblance to those of other individuals or to that of a universal consciousness. For this belief would render futile all attempts to learn from each other, to understand each other, or to achieve consensus. And why strive for a common vision apart from the conviction that this common vision bears some resemblance to reality? For then we would be limited to exploring the internal powers and possible objects of the human mind without reference to the way things truly are.

Now let’s revisit my two humbling experiences mentioned above. Admittedly, I cannot come to know and understand the experiences, thoughts and deeds of every human being who has ever lived. However, if I assume that all human beings possess the same powers, possibilities and weaknesses, I can learn more and more about my own humanity by studying the history of the human spirit in the lives of past individuals. (Reading entries from the Oxford Dictionary of the Christian Church makes sense after all!) Making the same assumption—that all human beings possess the same powers, possibilities and weaknesses—and thinking in the reverse direction, I can learn better to understand the experiences of other people by examining carefully my own first-hand experiences.

As I stumbled to answer my friend’s question about the state of the church in the United States, I ended up saying something like this: “I can’t speak from extensive, detailed knowledge of the big picture, but I can tell you how it looks from where I stand.” This humble and cautious approach seemed to satisfy my friend. He could compare his limited perspective with my limited perspective in a process that promised to clarify and supplement his understanding. Combined together many limited perspectives may move us all closer to the goal of comprehensive understanding.

The Third Lesson: Avoid both arrogance and despair (or dogmatism and skepticism) in your quest for true understanding. Listen carefully and dialogue respectfully to all voices and allow them to clarify and purify your first-hand understanding of the matter at issue.
