Only a few know, how much one must know to know how little one knows.– Werner Heisenberg (1901 – 1976)
In one sense, we don’t need to know much to know how little we know.
We just need to know that our thoughts are questions about the world, educated guesses at most. They are practical tools to help us orient and navigate in the world. Their role is not to give us any final or absolute answers to anything.
And yet, to know that, we often need to wade through a great deal of worldly knowledge. We need to know a lot about different things and see that what we know is a tiny drop in the ocean of all there is to know, and also that what we think we know often isn’t as certain or valid as we thought. Even our most basic assumptions are up for question.
At a social level, this is especially clear when we learn about the history of thought, science, and worldviews, and we see how different it is across cultures and how much all of it changes over time. What we take as a given today – about specifics and our worldview as a whole – will be seen as obsolete by future generations.
There is a shortcut to realizing how litte we know, and that is to examine our thoughts more directly. We can see how our mental “field” creates an overlay of images on the world and makes up what we think we know about ourselves, others, and the world. It’s all created in our own mind. None of it is “out there” inherent in anything. It’s all just questions about the world. None of it contains any final or absolute truth.
If we rely on knowing things to feel safe or loved or good about ourselves, then this can seem distressing. But, in reality, this realization and noticing is immensely freeing.
We get to see thoughts more as they are, and we get to see their role and function and what they can do – which is to provide some provisional and practical orientation and guidance, and what they cannot do – which is to provide any truths or final answers.
That goes for what we collective think we know and understand about the world. It applies to our personal lives and what we think we know about others, situations, and ourselves. And it applies to our most basic assumptions about existence.
