Tahirians And Holont

I am rereading Starfarers by Poul Anderson. In this novel, human beings interact with Tahirians and Holont. Since I summarized information about these two kinds of beings nearly three years ago, it is convenient to link to those posts now.

Other relevant posts are:

STL And Social Change

I think that there is a post summarizing information about the planet that the Tahirians are transforming but I cannot find that one right now. However, some blog readers might also like to search the blog?
