"The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself. Therefore all progress depends on the unreasonable man."
…according to Shaw, who's the unreasonable man in his example.
I'm gonna say that's bias to the point of being untrustworthy. You could also say 'therefore, the unreasonable one always gets his way, AND SO HE SHOULD'.
Reasonable person principle is about being a decent person it is not about Copernicus accepting geocentric model and living rest of life with it.
