 One natural kind of limit to democratic authority is the external kind of limit. Here the idea is that there are certain considerations that favor democratic decision making and there are certain values that are independent of democracy that may be at issue in democratic decisions. For example, many theories recognize core liberal rights—such as rights to property, bodily integrity, and freedom of thought and expression—as external limits to democratic authority. Locke is often interpreted as arguing that individuals have natural rights to property in themselves and the external world that democratic laws must respect in order to have legitimate authority (Locke 1690).
