As a Spaniard, I have to say that medieval ages are very different over centuries. The 7th century has nothing to do with the 13th one, which is a bit closer on mindset with the Enlightenment than the obscurity times.

Of course you have no way to get some/improvement in your life as a peasant except if you wanted to join a church which could give you some education and literacy. And a granted dinning table for sure.
