Nick's comment on "fundamental decencies" shows that he understood that his father's advice was within society's moral values, however, he allows himself to circumvent that advice and issue judgments, but keep it to himself.
We can arrive at this answer because:
- Nick is a man who judges people constantly.
- However, he keeps his judgments to himself, as he knows it's not right to divulge them.
- This is because judging people is not a moral value established by society.
- He learned this from his father, who stated that he must not judge anyone.
So Nick can see non-judgment as part of the "fundamental decencies" established in society, which are presented as correct, but which are not always followed by everyone.
