COURTESY is really doing unto others as you would be done unto, and the heart of it lies in a careful consideration for the feelings of other people. 

THE highest we can attain to is not knowledge, but sympathy with intelligence.

IF we are not responsible for the thoughts that pass our doors, we are at least responsible for those we admit and entertain.

we must let nothing pass our lips that charity would check;  we must be always ready to confess our ignorance, and to be silent

NOTHING, in our Lord’s wisdom, strikes me more than His moderation with regard to error.

NARROW-MINDEDNESS is a cause of self-sufficiency.   We are slow to believe what is beyond the scope of our vision.

PREJUDICE is opinion without judgment.

TO speak wisely may not always be easy, but not to speak ill requires only silence.

SPEAK fitly, or be silent wisely.

Those who really converse, reason without arguing, joke without punning, skilfully unite wit and reason, maxims and sallies, ingenious raillery and severe morality.
