> For most of my life I had assumed that all the people that had lived before our modern times were dumb. Really dumb. Borderline braindead.<p>It's an extreme strawperson argument. That's not what I think and thought of pre-modern people, nor does it match anything I've read.<p>They were biologically the same species as us. However, there was almost universal illiteracy and belief in things like causing sick people to bleed, witches, alchemy; embrace of extreme cruetly; disasterous (by modern standards) outcomes for lifespan, health, survival of children, justice, freedom, prosperity, famine, war, etc. etc.<p>We're not so perfect. The trick is to learn about humanity - about ourselves - from them, and look closely in the mirror for our own cruetly, etc. How many people die from lack of healthcare, for example?
