Thank you for the comment. As for the axes, the y-axis always denotes the desirability of the given value-system (except for Figure 1). And you are exactly right with the x-axis—that is a multidimensional space of value-systems that we put on a line, because drawing this in 3D (well, (multi+1)-D :-) ) would be a mess. I will see if I can make it somewhat clearer in the post.
