Machiavelli praised the political system and political system, believing that political system and political system can help promote social welfare, develop personal talents, and cultivate citizen virtues. He was a representative of Italy's emerging bourgeoisie in the late Middle Ages and advocated ending Italy's political division and establishing a strong centralized state. He believed that at that time, Italy was in a state of human depravity, national division, and social turmoil. The only way to achieve national unity and social peace was to establish a strong autocratic monarchy. He felt painfully that a strong monarch was needed to save Italy. Therefore, he strongly praised the deception, conspiracy, assassination and other violent methods of the conspirator at the time, Cesare Boggia, Duke of Valentino, and hoped that the monarch would follow his example and use various means to achieve the correct goal. These propositions of his are more comprehensively displayed in the book "On the King".
Machiavelli believes that human beings are extremely stupid and always have unsatisfied desires and inflated ambitions; they are always influenced by interests, seek advantages and avoid disadvantages, and are selfish. Therefore, altruism and justice do not exist, and people's occasional good deeds are just a disguise to gain fame and benefits. He believes that people are "ungrateful, double-minded, deceitful, pretending to be good people, desperate to save others, and greedy for profit"; even the best people are prone to corruption, because doing evil is more beneficial to themselves, and telling lies is more beneficial. Please others. People have a natural tendency to submit to power. What a monarch needs is cruelty, not love. People should choose lions and foxes among wild animals. They should be as cruel as lions and as cunning as foxes. A prince might as well take evil for granted and not be troubled by being accused of cruelty; compassion is dangerous, and human love is enough to destroy a country. Machiavelli famously said: "As long as the end is right, the means justifies the means."
