I don't know if you have ever seen, in the States, a comedy called 'Little Britain' ? - the only reason I mention the comedy is that one of the characters heeps saying, "Yeah but, no but, yeah but................". This is how I fell about this topic. It is a very interesting one, because it brings up so many arguments. I even started replying half an hour ago, then decided to go away, have a good think, and then come back to it.
No suffering and anguish ? It sounds fabulous; but like with all things, there are positives and negatives. I think that part of the learning curve of humanity includes access to each and every emotion; each and every experience. Take some element out of that, and I am not sure what we would be like.
With my own slant on my religious views, I feel that we do all need to experience everything - well, as much as possible. Without pain, the appreciation of Good health would be meaningless; without sorrow, similarly, joy would mean nothing.
Would we still find fulfillment in our lives ?
Ican see that those devout enough to give their time to charities, those who help the sick, those who work in third world countries, '
Médecins sans frontière' - none of these would exist. Without these opportunities for us to develop as humane humans, we would be greatly lacking in positive aspects and experience.
God's world (and I do call it God's world, with apologies and respectfor anyone who does not subscribe to 'God'), has pain and anguish 'built in'; animals feed on each other. We've all seen the programmes on television where a lioness catches up with a gazelle, and rips it's throat open. That is nature. that is the part of nature that fuels our need to survive, to better ourselves, to develop skills from our needs.
If I was a writer, I would have to summatize the lives of the people as 'unfulfilled, without purpose - boring, even'.
And don't forget that I speak as one who knows physical and mental pain; as do most of the population odf the world.
Still, images of Ethiopia, Darfur, The Congo, South America, ..... - well, I could go on forever, couldn't I ? - are flashing through my mind . I don't know. The world in the question doesn't exist, and no one could ever be able to forecast how a change would affect something as intrinsic as our world without experiencing it.
One last thought; we thought Tuberculosis was a thing of the past; we stopped giving our children vaccines for TB; what has happened ? Nature has come back with TB in full vengence; it is now a 'new danger' again. Medication (antibiotics) are having less and less effect on bacterial infections than they used to.
Perhaps this is Yin & yan.
