Traditionally–going back to the classics of Ancient Greece–the classification was based on the subject of study such as zoology, psychology, physics, chemistry etc.
In this century most studies are multi-disciplinary and a new system of classification of sciences is very necessary. The first thing one should take into account now is not the subject but the scientist, the mind of the scientist is the primary concern.
These scientific minds are attached to bodies that drive cars etc. and need money, these bodies carry IDs and are subject to governments and other pressure groups.
Most scientific endeavors are multi-disciplinary, therefore the key classification of science now becomes:
A) Public Science
this is what is done and published by independent individuals, scientists at universities and is published in books that can be found in the public domain, moderately financed. It is what one sees in such magazins as New Scientist, Scientific American etc.
B) Private Science
this is the advanced science and research known and done by scientists of the military, governmental, ‘national security’ guarded establishments and/or contractors, it is highly protected and secret and there are no known limits to funding.
One could also say there are free scientists and ‘captive’ scientists. Some scientists are free in the start of their careers and cease to be so. Victor Schauberger, who was forced to work for the Nazis was a typical example. There are also scientists who self-determinedly choose to work for governments, some captive scientists are posing as free scientists, just as is the case with their journalistic colleagues. And there are fortunately still a few advanced scientists, usually not main stream, who made it anyway into the public domain.
But keep the above separation in science in mind, it is symptomatic of the contemporary competitive culture on Earth.
