Ubi Arcano Dei Consilio §24

²⁴ The inordinate desire for pleasure, concupiscence of the flesh , sows the fatal seeds of division not only among families but likewise among states; the inordinate desire for possessions, concupiscence of the eyes , inevitably turns into class warfare and into social egotism; the inordinate desire to rule or to domineer over others, pride of life , soon becomes mere party or factional rivalries, manifesting itself in constant displays of conflicting ambitions and ending in open rebellion, in the crime of lese majeste, and even in national parricide.
