Never open the door to a lesser evil, for other and greater ones invariably slink in after it.
None is so perfect that he does not need at times the advice of others.
The path to greatness is along with others.
Better mad with the rest of the world than wise alone.
There is no wilderness like a life without friends; friendship multiplies blessings and minimizes misfortunes; it is a unique remedy against adversity, and it soothes the soul.
A man of honour should never forget what he is because he sees what others are.
