I choose just over rationality, but would argue I hope to be both.
That said, if I try to remain conscious of being just to those around me, those i like and don't know (or don't like), I should also be able to behave in a rational manner.
I think the danger of being rational is that with a surprisingly little amount of... neglect or denial or 'best intent' you can rationalize almost anything. And then claim rational thinking justifies your position/ behavior. Which does not mean the position/ behavior is just.
So I guess I believe the slippery slope is less obvious in 'being rational' as opposed to 'being just.' And I recognize that we live in an inherently unjust world, as exemplified by the rape vs. bank robbery example offered by vodkazvictim.
The corollary might be that in the 1930's and 1940's the Nazis rationalized the extermination of millions. But the action was not rational.
So I am skeptical about being 'one or the other.' And I am skeptical that the best of us manages to be either all of the time. Or honest. Or generous. Or even well intended. I would say I want to be a responsible person, except too often in our unjust, irrational world, taking responsibility triggers unfair consequences... I have a friend who spent a year in prison for accepting responsibility for business practices at his firm THAT HE HAD NOT PARTICIPIATED IN, while those who had taken part received no more time. And on top of that, the government could not prove anyone had actually been harmed. But it was post-Enron, and the defense attorneys were concerned ANY business man even accused might be sent away for 20 years or more. I find that unjust, and the general behavior of the US government to be irrational.
But at the core the government is responsible to the people, which i continue to believe is better than the opposite. So please do not misunderstand, I love my country, I simply disagree with many of it's policies and practices...
And we can have this discussion about which is preferable because of the freedom of our various nations... even if they are not always rational or just.
But enough of that... solid post, thanks for making me think... Now, back to the porn!
