Reveal not every secret you have to a friend, for how can you tell but that friend may hereafter become and enemy. And bring not all mischief you are able to upon an enemy, for he may one day become your friend.
However much you study, you cannot know without action. A donkey laden with books is neither an intellectual nor a wise man. Empty of essence, what learning has he whether upon him is firewood or book?
Human beings are members of a whole, In creation of one essence and soul. If one member is afflicted with pain, Other members uneasy will remain. If you have no sympathy for human pain, The name of human you cannot retain.
When a mean wretch cannot vie with another in virtue, out of his wickedness he begins to slander. The abject envious wretch will slander the virtuous man when absent, but when brought face to face his loquacious tongue becomes dumb.
