We wish we had a rational argument, but we are in a reasoned argument.
In a completely rational argument, empiricism is king. If the argument is about what temperature water boils, then we need only take a pan full of water, a thermometer, and a fire, and the answer becomes clear: 212 Good Old American degrees, or 100 Eurotrash degrees. Argument over.
We all love that sort of certainty, possibly more here. Whenever possible, we like to claim empirical certainty, because otherwise we are forced into the uncertainty of reason, of balancing conflicting data and interpretations.
For instance, we are comforted by empirical data about radiation, that it takes X amount of radiation to produce undesirable result Y. And, alternatively, it only takes X amount, etc.
But how much of that do we really know? Can we say, with authority, that we have enough examples of rampant irradiation to draw upon? Do we understand the nature of radiation sufficiently to have such precise epidemiology? Where would we have gotten it, given the relative paucity of such events as we are witnessing, the Goddess be praised?
We rightly put great faith in empirical evidence, we would all love to be as certain as a scientist can be, put the argument to experiment, and it is done. But to smack each other in the face with “empirical” evidence that is really an informed conjecture fails, it reduces our opportunity to a reasoned course of action.
Take, for instance, that chart outlining radiation doses/effects currently making the interrounds by the good grace of XKCD. It is remarkably precise, the hallmark of solid empirical evidence. But I have to wonder where and when the experiments were done? How much direct data do we have regarding the effect of radiation upon us water bags? I would hope not very much, and would want even less.
So, gentlepersons, pals and gals, let us set aside the pretense that we can solve this argument with direct experimental observation and the rock-solid solace of empirical data. We most likely cannot, we are forced into the realm of reason. Certainty is a sham in this discussion, we need to have ourselves a little slack-cutting party, even for the pro-nuke morons who are bent on irradiating our children till they glow in the dark and… Oops. Sorry. I’ll work on that.
