Found this amazing translated edition at an auction and got it for 2 eur! The book reads today less as an eccentric counter-Darwinian tract than as a visionary anticipation of several currents in modern biology. Specially where biology’s frontier is “collective and relational”: group selection, species societies, niche construction, gene-culture co-evolution, even systemic echoes of evo-devo. So rather than being “anti-Darwin”, he looks like a bridge figure: extending Darwinism into ecology, behavior, and culture well before the Extended Evolutionary Synthesis gave those ideas formal grounding.
