The relation between Locke's political views and his view of happiness should be pretty clear from what has been said. Since God has given each person the desire to pursue happiness as a law of nature, the government should not try to interfere with an individual's pursuit of happiness. Thus we have to give each person liberty: the freedom to live as he pleases, the freedom to experience his or her own kind of happiness so long as that freedom is compatible with the freedom of others to do likewise. Thus we derive the basic right of liberty from the right to pursue happiness. Even though Locke believed the path of virtue to be the “best bet” towards everlasting happiness, the government should not prescribe any particular path to happiness. First of all, it is impossible to compel virtue since it must be freely chosen by the individual. Furthermore, history has shown that attempts to impose happiness upon the people invariably result in profound unhappiness. Locke's viewpoint here is prophetic when we look at the failure of 20 th Century attempts to achieve utopia, whether through Fascism, Communism, or Nationalism.
In book III, Locke discusses abstract general ideas. Everything that exists in the world is a particular “thing.” General ideas occur when we group similar particular ideas and take away, or abstract, the differences until we are left only with the similarities. We then use these similarities to create a general term, such as “tree,” which is also a general idea. We form abstract general ideas for three reasons: it would be too hard to remember a different word for every particular thing that exists, having a different word for everything that exists would obstruct communication, and the goal of science is to generalize and categorize everything.
