Milton Friedman is almost certainly a liberal, in the classical sense. His belief in the sacrosanct nature of the free market, the need for limited and minimal government and his concern for human liberty clearly place him within a philosophical tradition of neoliberalism. The fact that he agrees with J.S. Mill that the individual should be free to pursue his own interests so long as they do not infringe upon the liberty of other individuals, is a strong indication of his admiration for 18th and 19th Century laissaiz-faire principles (as is the Adam Smith necktie he wore on the TV program "Free to Choose"!). Whether his re-popularisation of those principles can be considered "conservative" in the sense that he seeks a return to the pre-Roosevelt (i.e. pre-economic intervention) era, is debatable because the principles themselves lie squarely within the classical liberal tradition.
