I have always valued and admired intelligence, education, introspection and thoughtfulness above all else.
For many years I thought there was no such thing as "too introspective" and when George W. Bush talked about not being very introspective it made my already deep hatred for him that much deeper.
I also always hated the saying "the road to Hell is paved with good intentions" which I heard my very Catholic aunt say when I was very young. This irked me because I hated the idea that good intentions could lead to bad things. I didn't want to accept that. It actually bothered me a lot, even at a very young age, that people would say such a thing.
Just within the last half a year or so I've been undergoing somewhat of a transition in my political beliefs... even though I'm 32, and you might think that would be a point where you were fairly set in your ways.
I will never like republicans, or agree with their denial of science (evolution, global warming, their silly idea that people choose to be gay, etc) but I am starting to realize that there may be something to be said for a certain... clarity of thought, certitude, even if that certitude is not on the most firm footing.
I think the west has been paralyzed by too much introspection, we've lost our vigor and clarity of purpose and thought. So, in this sense maybe there can be such a thing as too much intelligence or knowledge. I instinctively reject that notion but... I wonder. I do wonder. Maybe the key is to pair intelligence and knowledge, with still having clarity and purpose and certitude. A difficult trick to pull off for many.
Likewise with good intentions, I now realize that they CAN in fact lead to horrible outcomes. The good intentions of bringing everyone into the melting pot of the US, trying to get along with everyone, be multicultural... I bought into this for 31 out of my 32 years. Now I am starting to think that some of the cultural forces at play in our world are too diametrically opposed, their history and starting point for thought too different from the western tradition... for a successful mixing to take place.
I believe there may be differences with the Islamic world, for instance, too fundamental for the result to be anything other than one civilization, or the other, ultimately falling.
I have to admit I admire the clarity of purpose and nationalistic solidarity the US had in, say, the earlier part of the 20th century, around WW2 most especially. Of course, I do understand a lot of this is rose-colored simplification of history. However, I don't think it can be denied that there was some truth to it.
