Be honorable yourself if you
wish to associate with honorable people.
The difference between a moral man and a man of honor is that the latter regrets a discreditable act, even when it has worked and he has not been caught.
H. L. Mencken
Real integrity is doing the right thing, knowing that nobody's going to know whether you did it or not.
Love all, trust a few, do wrong to none.
Wisdom is knowing what to do next;
virtue is doing it.
David Star Jordan
Do not believe in anything simply because you have heard it. Do not believe in anything simply because it is spoken and rumored by many. Do not believe in anything simply because it is found written in your religious books. Do not believe in anything merely on the authority of your teachers and elders. Do not believe in traditions because they have been handed down for many generations. But after observation and analysis, when you find that anything agrees with reason and is conducive to the good and benefit of one and all, then accept it and live up to it.
There is no pillow so soft as a clear conscience.
If we are ever in doubt about what to do,
it is a good rule to ask ourselves what we
shall wish on the morrow that we had done.
