As a young socialist, I generally avoided reading the acknowledged classics of socialist thought. This allowed me to persist in the pleasant and untested belief that someone had worked out a plausible comprehensive theory somewhere for how all this was supposed to work, and I just didn't know about it yet.
And so, if anyone asked me for my institutional model of socialism, I could gesture to these dense volumes and explain that someone smarter than me must have thought of it already. I was just here as an evangelist for a system that more profound minds had already worked out. How could they not have? Don't you see how thick their books are?
