Liberals and conservatives are opponents in the most literal sense, each using the myth of pure evil to demonize the other side and unite there own.

Liberals are experts in thinking about issues of victimization, equality, autonomy, athe rights of individuals, particularly those of minorities and nonconformists.  Conservatives, on the other hand, are experts in thinking about loyalty to the group, respect for authority and tradition, and sacredness.  When one side overwhelms the other, the results are likely to be ugly.  A society without liberals would be harsh and oppressive to many individuals.  A society without conservatives would lose many of the social structures and constraints that Durkheim showed are so valuable.  Anomie would increase along with freedom.  A good place to look for wisdom, therefor, is where you least expect to find it: in the minds of your opponents.  You already know the ideas common on your own side. If you can take off the blinders of the myth of pure evil, you might see some good ideas for the first time.
