Our understanding of nature is only the result of imperfect observations of nature. For example shadows or optical illusions can sometimes make us think that something exists when it does not exist. While we may have the observations of nature we must recognize that believing in all of those observations could be impractical and could be dangerous. Because not all observations are accurate and not all observations are truth so we must take actions based on an incomplete understanding of nature and what our mind assumes exists in nature.

In the book
The world is not always — or ever — exactly as it seems; a dirty, miserable ferry ride may, on a second look, turn out to be something else entirely. We never see reality directly; we see only a model of it, built from imperfect observations — and wisdom never forgets the difference. The danger is not ignorance — there is nothing wrong with not knowing — the danger is the man who is certain he knows what he does not. — The Instruments (Awareness/Perception/Expectations)
