I've spent a good part of my life just philosophizing to myself and trying to understand just what my positions are on issues. But I don't really think I became mature with how I treated my positions until I was nineteen when I started to have crystallized positions.
And I just am curious what constitutes maturity?
Is it unerring skepticism of all ideas without proof? It is the ability to accept that others have different opinions from you which can be equally valid and meaningful? Is it that two sides of a debate crop up not always from lack of information, but because there is no easy clear cut answer to what the end result is? Is it a complex melding of the whole.
I'm tending to think there are three big stages (I'm sure there's better speakers than me on the issues.)
One where you are a child and tend to accept whatever you are told to an extent, with some room for BS detection and the flights of fancy that is prone to child.
The adolescent which either finds a position and stubbornly clings to it like it is required for their survival, which may be just as much a rejection of their parents position as it can be acceptance... or what I did, which was bend and twist my position to whatever new fact seemed to overwhelm the one before and strong positions tended to swing me around.
And a Mature position which is based off personal preference, while allowing others to their personal preferences. On positions of policy and important decisions, these are positions based off personal facts and values, but there is a mature ability to debate with someone who holds another mature position. Perhaps with some insult humor thrown in, but it is only humor if the other man laughs with you. Sometimes the only option is to agree to disagree because you know the facts are the same, but what you value is entirely distinct from the other person.
But I am probably just playing amateur philosopher here. So other viewpoints and discussions is welcome.
