"Contrary to your requirement for measurement, botanical and biological classifications are not based on numbers, and are most definitely science."
Since I accepted Quiliro's view of a measurement ("it is, or it is not; 0 and 1"), botanical and biological issues are of course scientific ones. For example, a biologist defines "to be a member of the species xy, a plant has to look like ....) and then they can observe and conclude whether this plant is or is not part of the species. What you said about philosophy etc is true; my point of view only includes natural sciences. BUT if you include such fields like philosophy, then you can't refuse religion to be a scientific topic any longer. Theology has the same scientific value like philosophy, and the first one deals with religion as its topic. Perhaps we use the words in different ways due to language differences, but this does not change the inconsistency of their usage.
