From a toxicological standpoint, if you want to drink 10 liters of water then indeed you may just as well drink some arsenicum and not go through the hell of death by water poisoning.
But water is needed by your body in some quantity so you need to consume it anyway.
But is it 'good'?
No, it's nessesary, a nessesity.
I know these things BECAUSE of science.
We are experiencing miscommunication. I am stating precisely what you are saying: things are complex, and the only way to make sense of them is to use science.
I did read your links, and I know perfectly what you mean. We are talking past each other. My understanding of what you said was that since there is no clear distinction, it's not a scientific discussion.
if you, on the other hand are saying that because there is no clear distinction, we have to use science, then we are in agreement.
The same applies for well being. And, among all the shades of grey, if you take the extremes, there
will be a clear distinction, as there is with food and poison. There is no doubt that 1 liter of arsenic if poisonous for humans (it's actually lethal). 10 liters of water can be pretty bad for you, might even kill you, but 20 cl are pretty good for you. It's a degree, a range of values.
Science itself is (moral)value-less, it's moral-agnostic if you will.
It can be used for what some consider good and it can be used for what some consider evil.
Science cannot decide what is good or bad or evil, humans can.
And we certainly do use science to make up our opinion about good and bad and evil.
But you have to realise that the value comes om us, humans, not the science or the scientific method.
I think I wrote this at least 10 times, but apparently you care more to write than to read.
I am setting the matter of morals aside for the moment, I am interested in discussing how to achieve the following goals, which I stated before: survival of the species, sustainability, nurturing and creative environment are all favourable conditions that can be evaluated, measured, studied and tested scientifically.
Facts, not opinions.
