Help! I am becoming a communist!

First, I greedily consume a novel by an avowed communist and didn't know it.

Then I stumble onto this quote:

“[People] make their history… not under circumstances chosen by themselves but under circumstances directly encountered, given and transmitted from the past. The tradition of all dead generations weighs like a nightmare on the brain of the living.” ~ Karl Marx

and I think it is the truest thing I've read in the last week.
