Inside the VR of our brains, we attempt to create patterns of information that describe the universe outside of our brains.

For example Newton's second law:  F = ma. This is a type of knowledge that we can use to describe and predict the outside world.

To the extent that this knowledge actually describes the outside world, then it contains truth.

There is nothing subjective about whether F = ma describes the outside world or "contains truth", however we can never know for sure if it does.

For value, it depends on what is meant by it. I see it often as a type of moral knowledge. Given the knowledge I know, what SHOULD I do? 

Should I value skydiving for example.
