Known unknown and unknowable

We are all taught what is known, but we rarely learn about what is not known, and we almost never learn about the unknowable. That bias can lead to misconceptions about the world around us.

The known is pressed on us from the first.

Even when we are right on the edge ofthe unknown, we may not be aware of it.

Be aware of something, and be aware of the way of the communication with something.

In school we start each course at the beginning of a long book full of things that are known but that we do not yet know.

We understand that beyond that book lies another book and that beyond that course lies another course. The frontier of knowledge, where it finally borders on the unknown, seems far away and irrelevant, separated from us by an apparently endless expansion of the unknown.
