Hazy and fuzzy answers were not an option. If they could not find the right answer, the only choice was to keep on trying till they did. This often meant they had to break down the questions and tests into smaller and smaller parts. They would often need to do this so they could measure their test results. Scientific testing and clear thinking need hard facts to get the right answers.
Natural science uses a form of logic that puts things into classes.
Science types things by taking great care to look at how they are alike and how they differ. A difference may mean a thing or life form ends up as a new class or type. We may put a thing or life form that is like the others in the same group or class. This system of classifying things helps scientists to understand the broad links between life forms and the lifeless world. It's too bad that the public often missed all these links.
