Machiavelli on Republic states and Hereditary Lineage

Machiavelli spent much of the second half of his life concerned with regaining a governmental position in Italy following their political coup. For a statesman, ironically, Machiavelli was a quiet and shadowy individual, though his opinions on political rule are strong and controversial. He believed that a prince must always present himself as perfect and that all countries out to have a constant cavalry in order to have a fortress of sorts(though he disapproved of most stone fortresses). This made sense in his time due to the roaming barbarians that would eventually take over his country. Machiavelli believed no man can hold power without a knowledge of tactics and to trust no one. Such a Prince has only few advisers and admirers are brushed off, otherwise the Prince will lose respect, a ruler he says must be simultaneously generous, holding festivals, and mean or brusque, occasionally cruel without reason. Do you agree with his philosophy? Do you find it hypocritical?
