When you decide whether to give your support to a party of the Left or of the Right, you are actually making a judgment about what you think politics is for. If you believe that it is the function of government to alter or determine people's perceptions and responses – their innermost feelings about themselves and others – then you will probably opt for the Left. If you take the view that the state should concern itself only with behaviour – with what people do, especially insofar as it affects other people, rather than what they think or feel – then you will be more likely to veer to the Right. So this is really a question of whether you want politics to be concerned with what goes on in people's heads as much as with events in the objective world.
