Why pragmatism is dangerous

The Prime Minister has just announced that he would wish to make changes to the Human Rights Act. I have a problem with this. The basic issue is that this PM and his party are not guided by founding principles. The high theme of this government is "whatever works". For me that is extremely dangerous. A state that fails to establish explicitly where its limits truly are will expand to control all things. Political principles are not about what the State should do , but about what the state should not do. These limits to state power are the key to a successful democracy. The Human Rights act explicitly sets out what the State may not do. Tinkering with it can only increase the scope of state power and that must be resisted.
