Yes, we can define so-and-so as a hydrogen atom, but to get to this point we need to have seen lots of things and established that there are sufficient commonalities between things that make them different from other kinds of things; different enough to put them together as 'hydrogen atoms'. While the definition is fine, the method by which we decide it fits into that category brings in the issues I related above. And you have to have the assumptions in your method, as they form the difference between 'Hydrogen atoms always have one proton in their nucleus' and 'Wonderflonium only occurs during a crazy random happenstance'. One has meaning because we've decided based on empirical data that it is an explanation; the latter is simply made up, lacking the same empirical grounding.

"Hydrogen" is defined to have one proton. Atoms exist that only have one proton. Therefore they are hydrogen atoms.
Whether or not we can determine if sample X is a hydrogen atom or contains hydrogen atoms, involves some of the assumptions you mentioned (which you could've just shortened down to "inductive reasoning"). It doesn't matter if we cannot determine what is in sample X, a hydrogen atom will always have one proton, that is a truth free from bias or world view.

For that matter, why do we call Hydrogen an atom, when - by definition - it is merely a proton?
Because it has an electron, usually? Fine, but what about an isotope that doesn't, is it still an atom? Why?
The manner in which we define things, and the criteria we choose, are indicative of our world view. I'll grant you that there are objective facts, BUT we aren't able to understand them completely objectively and we certainly cannot communicate them objectively.

So while the mine company would say it doesn't effect the river upstream of the mine, indigenous people would argue otherwise. I would be reluctant to dismiss the validity of the latter worldview merely because it conflicts with positivism; the situation is more complex.

It is still possible to be wrong. Do not insult the human race by suggesting that opinion (aka local conviction) has just as much claim to truth as a scientific approach.
the Empress wrote:Ok Tedi was a complex situation. In fact *you* are dismissing an entire worldview.
Considerable damage was done to the environment indigenous people were dependent on and negotiation was stalled by the incapacity of the company to engage with a local culture. It's an example where worldview towards 'truth' caused considerable conflict.
My point is, positivism is one way of thinking about the world. I'm not saying it's bad or good, but it's the model in which physical science operates. Extrapolating this worldview into every situation, with the assumption that there is one 'real' truth which can be known is not always useful nor is it the only valid worldview.

And this is the point in the conversation where the physics and chemistry students get their revenge by confusing the poor saps who haven't studied the structure of the atom. Anyone care to throw some physics language in there?

I'm not on some crusade against physical science. It exists within a particular worldview. Someone stated earlier it didn't. I'm reluctant to go into the Ok Tedi case further, because I have actual work to do. However, it's a case demonstrating the need to consider other worldviews, particularly within development. It' made an impact within the mining field. It relates to earlier arguments about the attitudes of scientists further up this thread.
