>This analogy is not generally accepted by most philosophers. Briefly: philosophy is not a science.

Which philosophers are you referring to? I'd agree with "many" but "most" is an empirical claim I'd not be brave enough to make. Do you perhaps mean to say "economics isn't a natural science"?

Case in point: there is tons of kuhnians running around that think of science as a consent-seeking endeavor with agreed upon principles. They recognise that any hard delineation between say econ not being a science but physics being one, usually kicks out a lot of progress in physics as not scientific. Especially those theoretical physics whose predictions are extremely fruitful bbut where experimental data is out of reach right now.
