Classical liberals favor democracy because it operates as a ruling of the people by the people, rather than rule by someone else.
This lends itself to the concept of negative freedom, or freedom from being compelled by the state or other authority to do something. So Daniel Jacobson, professor of philosophy at University of Michigan, raises the question: Do we have absolute sovereignty over our bodies?
The crucial point for liberalism is that liberty ought to be the default. It shouldn’t be easy to justify compulsion.
