I personally am allways looking for vulgarity, it is to me as sweet as the scent of roses. Which brings me to the following point.
You speak somewhat derisively about informal use of language in this case. But in my opinion, complicated language does not increase the authority or clarity of that which is said, if anything, it clouds the facts and provides a lot of food for discussion about unimportant matter that is far beside the argument.
For me, and the three year old, it's better if you first formulate your thoughts as "a casual approximation which might fly for a bit." and then, when people start poking holes in it, you go on to fortify your theory with smart arguments.
Yet this is not what I observe in this discussion, and I know I am not the only one here who was confused. Take BillyHoyt, he's still wrestling with your first analogy, he hasn't even started on the double helix nonsense.
But luckily I also see that with the help of your last few posts, I'm getting there, which is nice.
On the P.S.-es: I can't answer that question yet as I don't know what you mean by the "challenge of existence". The existence of what?
And my native language is indeed Dutch.
