Words can certainly be defined, since humans construct them. Natural 
phenomena can only usefully be described, since any definition can be 
falsified with additional data.

On the other hand, all useful scientific inquiry is informed by theory, 
either explicitly or implicitly, so it's useful to get our theories out 
in the open so we can better understand preconceptions that might 
mislead us.
