The main purpose of the book is what a ruler needs to do to maintain political power while being attacked by foreign powers. The thesis in the book stated in the introduction is "The immediate practical purpose of The Prince radically original treatment of crucial philosophical and political issues continues to attract new readers, many of whom are often unaware of any practical political goal Machiavelli might have intended in his argument." The central themes that were I noticed while reading this book was the statesmanship and warcraft; goodwill and hatred; virtue and fortune. The themes were often stated throughout the book with statesmanship and warcraft, Machiavelli stated on page 43 that "where good armies exist there must be good laws." During the freewill and hatred, stated on page 62 "the prince should concentrate upon avoiding those things that make him hated and contemptible." Virtue and fortune were often a big issue in the book; Machiavelli says that a prince should have more virtue than base his power on fortune. The conclusion that is brought by Machiavelli is the fact that if a prince follows his suggests he will be able to maintain rule through all costs. The most important message that Machiavelli tried to get across is that fortune can take control over a man's thoughts and a man's virtue is the only thing that can keep a man on the right track and not fall through from fortune.
