What does the following quote mean? 

"I don't know half of you half as well as I should like; and I like less than half of you half as well as you deserve"
The exact meaning of this quote is unclear, but it could be a reference to an ancient Greek saying that people are not fully known or understood by others, and that each person deserves respect and love based on their own unique qualities. The idea that we need to strive to understand and appreciate one another more deeply can also be interpreted as a call for greater empathy and altruism.
