The first branch of which rule containeth the first and fundamental law of nature, which is: to seek peace and follow it. The second, the sum of the right of nature, which is: by all means we can to defend ourselves. Right, for hobbes concerns the liberty or freedom to do a particular action. Recall, in the state of nature, all persons have a right to all things that they judge as necessary for their preservation. It is very important to note, rights for hobbes, in the state of nature, do not have any corresponding duties of others. Duty, as we normally understand it, implies an obligation to refrain from doing something or obligation to do something (negative and positive duty). Obligation, as such, implies the lack of liberty or freedom following from another"s right. But, for hobbes, since everyone has a right to everything, it does not make sense to speak of duties.
