Acquired Rights
284. Among the connatural rights of the third class, which make up innate relative freedom, I stated the general right `to posit all the lawful actions that are useful to us and cannot reasonably be impeded by others, and to acquire other rights by means of our connatural rights' (cf. 273). When exercised by us, the connatural right to posit these actions becomes the universal source of all our acquired rights.
285. Because all rights acquired in this way are founded in a connatural right, the present work, dealing with acquired rights, continues and flows from the previous book on connatural rights. I have therefore already expounded in the previous book the effective principle of the whole study of acquired rights.
286. We will begin by seeing how acquired rights come into being, and by investigating their act of acquisition and the nature of their efficient cause.
