Science is knowledge (scientia) that is systematically gained and/or organized. That entails that the terminology of science be systematic, i.e, a nomenclature rather than a hodgepodge of terms. This can make discussions about science hard since people have to learn a body of nomenclature before understanding a science. This applies to all sciences, whether natural sciences, social sciences, historical sciences, or subjects with some systematization such as systematic theology.
But a more pressing challenge for discussions of science is the use of words that have both technical and non-technical meanings. Within a science only the technical usage should apply but discussions of a science inevitably use some of the same words from general usage as well. So terms with a precise meaning within a science are used along with the same term with an imprecise or ambiguous meaning.
If this were a problem that applied only to minor terms that would be a minor problem but it is a problem with major terms and terms whose meaning is disputed. The result is that people who disagree are talking past one another, misunderstanding one another, and fail to communicate. This happens especially in cases of controversy or strong disagreement. What can be done about it?
One solution is to qualify terms so it is clear what meaning is intended. For example, instead of saying “evolution” specify “unguided evolution”, “guided evolution” or “theistic evolution”. Instead of saying “design” specify “intelligent design”, “intentional design” or “divine design”. Instead of saying “creation” specify “transcendent creation”, “special creation” or “intelligent creation”. These qualified terms should be defined but the presence of a qualifier alerts people to the more specific meaning intended.
