结合下文看，“父亲”这句意犹未尽的话是在告诉“我”：
你天生就有的那些道德感别人不一定有，所以就对别人宽容
一点吧，不要去批评别人。是宽容的问题，不是“资格”的
问题。

Reserving judgments is a matter of infinite hope. I am still a little afraid of missing something if I forget that, as my father snobbishly suggested, and I snobbishly repeat, a sense of the fundamental decencies is parcelled out unequally at birth.
And, after boasting this way of my tolerance, I come to the admission that it has a limit.
