Science is a way to teach how something gets to be known, what is not known, to what extent things are known (for nothing is known absolutely), how to handle doubt and uncertainty, what the rules of evidence are, how to think about things so that judgments can be made, how to distinguish truth from fraud, and from show.

What is not surrounded by uncertainty cannot be the truth.

But logic is not all, one needs one's heart to follow an idea.
