It seems to me the story you posted furthers my point: the Rabbi’s genius, again for reasons we can not fathom (I believe we are taught some Rabbis were very handsome and others were not) caused him to look ugly (at least in the eyes of vain and rude people; we surely should assume the rav’s wife found him attractive, should not we?) Also, I believe in the future world we will have a resemblance to our appearance in this world, correct me if I am wrong.
See, the point is, we have people without eyesight, we have people without limbs, we have tetraplegics, countless diseases – we correctly say – along with Western culture – we should help them live to the fullest. To that aim, we scream against work discrimination (even though we are well aware that, say, a healthy employee’s productivity is different). We promote sports and other activities, nowadays there are many athletes among them. We even become angry at words such as “blind” or even “disabled”, we mandate words to define them and enforce that with laws and with social stigma. However the main point remains: no one wishes upon ourselves and our children to be like that. While we can (and should) try to support every human being – disabled or not – to live to the fullest and to fulfill their wishes, the fact remains that they are different and we don’t know why and we can’t help it. This is the real, serious problem. We can say, I do not know why. Or we can try to rationalize, although I have the impression that the very few persons who are at such a high level they’re able to, do not discuss this with unlearned people.
