We know a little bit more today than we used to know,  but we still know too little, and certainly there are  many different processes — economic, social, political — that need to be studied more.
Danas znamo nešto više no što smo nekad znali, ali još uvijek znamo premalo, a zasigurno je mnogo različitih procesa -- ekonomskih, društvenih, političkih -- koje treba i dalje proučavati.
