[Hmmm. That raises a question:
What are the rules of science?
What is the rule that allows scientists to construct mind-dependent beings (ens rationis) that are true to the presumed mind-independent beings (ens reale)?
It seems that the mind-dependent being must image or point to ‘the subject of study’, thereby producing a sign-object in the mind of the scientist.
Models provide images.
Experimentation provides indexes.]
