The Gemaros themselves, that means Niglah alone accounts for the idea that there are two levels in the definitions of צדיק בינוני ורשע.
1) As it relates to being judged, where as a practical matter one is a צדיק if most of ones deeds are good etc.
2) מהות מדריגת צדיק ובינוני ורשע, where there is an entire new sets of definitions for these terms, as will be discussed in the subsequent classes.
