What Have We Done - Raising Children and Human Freedom

My youngest son (17) is just back from an academic program at University of Dallas.  Two weeks with 20 or so other teens, reading literature and philosophy, playing capture the flag and ultimate frisbee, making new friends and flirting (quite a bit).  He had a great time.
We spent the evening receiving a bit of a data dump on his experiences there.  Much of what we heard were biographies of those he became friends with, the pranks they played, the jokes they told - but peppered in there were references to discussions of John Donne and Nietzche at 2AM (there was a curfew but sounds like it was routinely broken by these "great kids").  It warms a mother's (and a father's) heart.....
Sounds like UD has become a possibility for college applications.  That was part of our intent in spending the money to send him.  UD or not, it seemed like a program that would benefit him in several ways - resume building, perspective building.  The outcome seems to have fulfilled our hopes - he's full of comments about Antigone, Agammemnon and Shakespeare's Sonnet 94 (which I have been informed is "chill" - current teen speak for cool).  He wants to finish memorizing it. ( I am trying to contain myself!) 
Whether Prince 94 ends up going to UD or somewhere else our money was well spent, invested, in sending him to the summer program.
These kind of investments are part of proposing a way of life, of a way of focusing on eternal and essential truths to our children.  And this proposal is itself an essential element in respecting the freedom, the human freedom of our children.  In this, we imitate our Father who is the originator of our freedom.  He proposes Life to us and we in our turn, join in proposing Life to our maturing children.
