This post is entitled "On Liberalism", and as such is about liberalism. Let's break it down etymologically, shall we? "On" meaning "about" or "concerned with". That's the easy part.
"Liberalism" is from the Latin word "liber", meaning "free". As such, the term "liberal" concerns itself with freedom. In this analysis, I will mostly concern myself with English usage. Even that is slightly beyond the limits of my expertise, but I press on.
At one time, before the modern era, "liberal" was primarily associated with largess, or freedom of action. Another common sense of use was in the sense of the "liberal arts". This was a "free" education, meant to equip the student to respond to challenges from trains of thought outside of purely Christian development. It was contrasted with scholastic modes of education that were more rigid and admitted less wandering.
I have it from no less authority than Winston Churchill when I say that the term "liberal" was first used in a political sense during the Spanish Civil War of the 1820-23. It was associated with Enlightenment trains of thought that agitated against government by monarchy in 19th-century Europe. In varying degrees, since that time, the term "liberal" has been applied to those who desire to peel back traditional and cultural norms with the stated goal of "progress". As opposed to this definition, a "conservative" was one who wished in some way to preserve these same institutions for the good of nations in particular and societies in general.
"So why call your blog 'This Liberal Blog'?". Good question. Liberalism isn't a defining life ethic, or at least not one of very much value. But it is an inclination, or a general leaning, with which I identify. I believe that "liberality" in thought and education, meaning freedom, allow us to fully take ownership of our cultural legacy. I believe it is necessary to distinguish between liberality and license.
Many of the forces that have appropriated the term "liberal" are in fact proponents of license. License demands freedom for its own sake, to do what it wants. In contrast, liberality only asks for the freedom to determine what is right and to do it.
And for that, I am a liberal.
