Based on what you're saying here, are you arguing for a kind of Scholasticism?
Finally, your criticism of a "radically egalitarian" view is somewhat perplexing to me. Would you mind expanding on that point?
And yes, a teleological philosophy like scholasticism makes the most sense if we are trying to figure out the best way to live. Otherwise we just end up with the specious word game philosophy that everyone hates
Because nobody could read and copies the bible were sparse the catholic church was the single source of word of god. The printing press changed things. The bible became widespread and people read the bible for themselves. With that came an important shift, that one's own interpretation of a text was a valid interpretation. Tons of important literary works became widespread. The middle class valued literacy and saw it as a ticket to wealth and began teaching their kids to read and write competitively at younger and younger ages. They invented the education system we have today; the entire idea of a sequential learning system based around books, and becoming an adult when you could read at a certain level (as opposed to the catholic belief that you were an adult when you were old enough to fight at age ten), that was also the enlightenment and romantic period. Protestantism came about because people valued individual interpretations of the bible, which the catholic church had serious qualms with since that was their entire claim to authority...
So the fact that you grew up in a family which valued literacy, which sent you to a university where you spent four years reading books, and then came out of that with your own valid and rational ideas about what those texts mean, and your rite of passage into adulthood is based on your ability to read and write at a university level, that is still very much framed in the values of the enlightenment.
A good book for you to check out is Rodney Stark's "For the Glory of God", written by a secular historian debunking much of the above narrative.
The fact that many educated today take your narrative for unarguable fact also illustrates the problem. The 'enlightenment' narrative is ironically very self limiting.
As far as protestantism and the printing press being invented prior to the enlightenment, yeah. Without widespread use of both you don't get the enlightenment for reasons I mentioned previously. And neither were really new ideas, either. Ancient greece had the printing press, high rates of literacy and a belief in interpreting texts for yourself, but these ideas were lost during the dark ages.
At any rate, we are obviously referring to different things by the term 'enlightenment', definitely different historical epochs.
