Should knowledge be useful or accurate?

Question from the Internet:

“To what extent should knowledge be useful rather than accurate?”

For knowledge to be useful, it needs to be “true”, meaning it needs to be based on and reflecting actual reality.

In order to attain true and actual knowledge, we need objective perception of reality and an ability to discern true facts from false ones.

And here is our problem.

Our inherent consciousness and perception of reality is 100% false. We receive impression fro “a reality” through our individually tuned physical senses, and whatever input we receive is sorted and evaluated through our 100% egocentric and subjective filters and then this already filtered and distorted data is computed and prepared by a 100% self-serving and self-justifying, individualistic “pleasure/pain” software. And as a result, a certain reality is built and projected around us by this apparatus, and we live in this 100% personal reality according to what we desire, want and aspire for.

Any “truth” or “knowledge” we ascertrain is “ours”, the “facts” we base everything on are “our own facts”.

If we wanted the “real truth” and wanted useful knowledge, firs, we would need to acquire a purified and transparent, selfless and objective viewpoint on reality and an intellect that can work totally selflessly and accurately as if the “I” did not exist, only a pure, unbiased and totally objective observer.

This is actually possible. But in order to reach it we need to make a conscious decision that we are willing to give up and go above our original self-serving, self-justifying, subjective and individualistic viewpoint and start relating to others and the world “as if we we did not exist or matter”. Then when we accept this and are willing to go through a process that leads to such pure and transparent and unbiased viewpoint, we can strat learning and practicing a way of life and a way of observing life which leads to acquiring a totally selfless and objective viewpoint of reality.
