When I started the publication project with Herbert Gintis on
the homo socialis (Gintis and Helbing, 2015), the most important
motive for me was to trigger a scientific debate. So, from my
perspective, our joint paper on the homo socialis is not to be seen
as an end point or eternal truth, but as the starting point of a new
theory for socio-economic systems. In this comment, I will expand
on my paper with Herbert Gintis, and I will use the opportunity
to present some further thoughts and materials.
