Here's a slightly different definition of conservative that may add to the debate
(Taken from a Guardian article about a government study -
see at
http://www.guardian.co.uk/international/st...017505,00.html)"conservatism can be explained psychologically as a set of neuroses rooted in 'fear and aggression, dogmatism and the intolerance of ambiguity'."
Of course, reading to the end of the article this is added:
"The variables we talk about are general human dimensions," he said. "These are the same dimensions that contribute to loyalty and commitment to the group. Liberals might be less intolerant of ambiguity, but they may be less decisive, less committed, less loyal."
Which I think is a valid point. Conservativism defined in a broader sense than Republican - can enhance society in some ways. It tends to be a normalizing force. During great social change and massive upheaval, people might out of fear return to look at the idealized past and lament the loss. This can lead to many negative problems (as mentioned, prejudice, hatred and etc) but also to positive additions in a compromise between the liberal forces of massive change and the conservative desire to remain unchanged. The liberal may bring the new ideas, and fight for them to the death - but without the conservative voice to lend some sense of constancy, the lofty ideas can lead ultimately to their own destruction.
I think each of us (even me, an avowed liberal) have conservative tendencies. We desire to spend holidays with familiar faces, we want to wake up each morning and know that the world outside my window will look the same. (I want my car to still be where I parked it the night before) But inevitably, things will change - children grow up and move far away, buildings fall to nature and man (my car gets towed). And it is the liberal ability to accept these changes that keeps us from despairing over the loss of a familiar landmark... but ultimately it is the conservative that will accept the changes and make them part of the status quo once again. Then the ideas that the liberal fought for yesterday become part of the institution today - so the massive civil liberties drive in the sixties has today become the institution that future children will take as given fact. Indeed, the true conservative (in a strictly theoretical definition of the term) will fight to keep the civil liberties against any who want to erase them - because they are now part of the institution and known universe we have grown accustomed to.
For more specific examples of the positive contribution made by conservatism, I can think as far back to the beginning of our country. There were two rather publicized revolutions within a decade of each other, but only one was successful. In America, the forces of change (we'll just call them the liberals) fought to change the entire political system when the status quo of subjugation to a king became intolerable. There was a massive upheaval, but it was ultimately the conservative desire that would lead to the final formation of a lasting union - because while one part of their lives changed (rule by the people vs monarch), the people ultimately wanted to return to a *normal* life and no longer wished to fight. In France, the liberal forces fought against the same system of monarchy, but the people ultimately could not establish a lasting democracy at that time because the conservatives could not gain enough power to quell further rebellions/change in the government. So, the people were subjected to years of war and terror, until a strong (ultimately conservative) force came to power and reinstated a monarchy.
I'll end this long post with the additional consideration that had the conservatives not won in 1865, we would not have the same country to worry about. I'm afraid this prob deviates from the initial topic idea - but I also have a hard time considering the current leadership as any kind of good conservatism - I tend to associate their neo-conservatism with nothing but negatives and so try to differentiate between neo-conservatism and just conservatism.
