He has a lot of individualistic notions, for example, the idea of a social contract, but his view of individuals is as empty vessels that are filled by society. These find different expression in different societies. This encourages people to vote to reproduce the ideal society over time. Note also that this is a dynamic, historical process, rather than R's mythical hope that an all-wise Legislator would come along and design the perfect society to be imposed on people. His hoped-for proletarian social contract involves disalienation, a potential within humanity.
R is very readable.
I haven't read far beyond those.
