Human nature are guided by self interest but are concerned for others.
The state should only govern by consent, limited government - social contract theory, for a 'true' state (rejects divine right to govern)
Natural laws and natural rights of society predate the state.
Private property is a natural right and the state's role is merely to arbitrate between individuals competing for trade and resources.
Powers should be dispersed - exec, legislative, judiciary
Not a full democrat - accepted property rights and the way this leads to some inequalities.
