You use a peculiarly limited definition of 'science.' According to
The Dictionary (that is the Oxford English Dictionary) science is
characterised by concern with knowledge and theory. Philosophy can
properly be called a science. The four software freedoms are a work
of philosophy and therefore science.
Contrary to your requirement for measurement, botanical and
biological classifications are not based on numbers, and are most
definitely science.
If by science you mean 'based on the scientific method,' then I ask
you what is using Trisquel if it is not taking part in an experiment
on the validity of a philosophy.
OTOH it might be that the .de (or other) word you are translating
from is slightly unlike the English word and more specific. The
English word is a borrow from Spanish and Portuguese, so it's less
likely there's confusion on Quiliro's part.
