What do we actually know about nature?
The things we know are what we conceive them to be.

How much do we actually know?
We don’t have accurate knowledge about everything we claim to know.

Misleading information exists everywhere.
How can we tell whether the things we know are true or false?

Some people seek knowledge about many things.
Others just want to know enough to get by.

We should not believe only what we see.
Many things exist beyond our knowledge.

Not everything we know is worth knowing.
We don’t always benefit from all the things we know.

Do we need useless knowledge?
Knowing helpful things is what really matters.

Astronomers think they know the mystery of the universe,
But they don’t know that they don’t know.

Supernatural beings didn’t tell humans anything.
It might surprise us that things aren’t what we think they are.
