The empirical theorists believe that an empirical science of politics based on facts alone is possible, whereas the others, the trans-empirical theorists, are of the opinion that the study of politics neither can nor should be purely scientific.
The transempiricists, on the other hand, believe that whatever be the situation in the natural sciences, facts and values are so closely inter-twined with each other that, in the study of politics, one can not separate them except in the most trivial instances.
