Precepts of lord Ptah-hotep
Ptah-hotep was vizier under Jedkare Isesi 2350 BC - I admire the thoughts of this very ancient and honourable man. Here is one of his guidelines for all the sleazy and corrupt politicians.
“If you have become great after having been little, if you have become rich after having been poor, when you are at the head of the city, know how not to take advantage of the fact that you have reached the first rank.
Harden not your heart because of your elevation; you are become only the administrator, the prefect, of the provisions which belong to Ptah.
Put not behind you the neighbor who is like you; be unto him as a companion."
