What is moral may not be rational.
What is rational may not be moral.
Rationality comes from the intellect, yet, there are things which can not be grasped by the intellect. For a good example, read a few of things written by William Barret. Or if your into mysticism, you can even go and try Wililam James ... or if you wanna get really hardcore, try Heidegger ...
As for morality for oneself ... well, yeah, I agree ... but who can reach that level? Remember the story I wrote about in another thread. If you have not read it, I will remind you here.
I was in iaido class and my instructor once said to me, "when you have reached fourth dan, you will draw your sword how you think it should be drawn. Not the way you were taught or the way other do it. And this is when you are not learning martial arts, but when martial arts learns you ..." Coincidentally, in another martial arts class, another instructor said, "when you reach fourth dan, you will throw a punch how you think a punch should be thrown and not the way you learned or the way someone else of higher rank does it ..."
By why fourth dan? Because you can reach third dan and still be mechnical. But yet, martial arts is call martial "arts" simply because it is a art form. But someone of lower ranking will not the "art" out of it because they are merely following and mimicing others, namely, the instructor ... so it is very mechnical, very scientific if you will. But if "copying" and just mimicing and learning the forms is the pinnicale of martial arts, why call it martial arts instead of martial "science" ... the answer is self evident ...
My main point being is, not many people can reach fourth dan, just like not many people can be "individualistic" without being egoistic and selfish. Just like not many people can reach self-actualization. Additionally, morality is indeed a social/collective issue. For instance, cannibalism and polygamy is accepted in some cultures while shunned in others. Morality is relative to the culture and culture is a social/collective thing ...
A Westerner is very likely to be raised with Christian morality whereas a Hindu is raised with Hindu morality just like an East Asian is raised with Confucian morality ... you can not escape that. Meaning we will always be a "camel" as noted in the Three Metamorphoses as stated by Zarathustra. I mean, personally, one of the reasons why "witty" has become a "virtue" in the West is because of Machiavelli, who turned Christianity upside down ...
Nonetheless, in the extreme, I do agree that indivdual consciousness is the highest human achivement, yet, not everyone, in fact, very few can reach this stage ... and I am definitely not one of them ...
As for being on topic, well ... all I can say is this:
The Nazis and the Japanese thought what they did was rational. And up until the US jumped in, it seemed that the Axis were succeeding in their gloabl conquest. Therefore, does that mean killing Jews was also rational? Arendt says no because she said Hitler was too obsessed about killing Jews instead of staying on track. I personally think the most rational thing to do with conquered peoples is to get them to work for you ... why kill them when you can use their specializations and knowledge into new things? Not to mention the added manpower ... and that's one of the reasons why the Mongols were so successful ...
So, because they (Axis) lost the war, does it automatically make their gobal campaigns irrational and hence immoral? Well, then, the Mongols "terrorized" many and were highly successful in their conquest but were immoral in the eyes of the terrorized. So does rationality and morality go hand in hand?
As stated earlier in this post, what is rational may not be moral and what is moral may not be rational ...
