We all tend to shoot from the hip here. That's why threads wander so much.
I like Walt Whitman a great deal. One of my favorite quotes is
"Do I contradict myself? Very well then, I contradict myself. I am large, I contain multitudes."
It seems to me that a failure to wander, or a failure to risk wandering, smacks of intellectual arrogance. While certainly there is a logical limit to mental exploration and its accompanying linguistic representation, most of us are probably a hodge-podge assemby of viewpoints that we are trying to order into a whole. Personally, I think the more viewpoints one can accurately represent, the better he or she ends up representing their own point of view.
Constrast that with some of the extremeness presented from both the hard right and the hard left... it can get ugly sometimes.
It sounds like the anthropic principle (weak or strong) is little more than a way of trying to understand things in human terms. Valuable for understanding, perhaps, but it seems to me to be skewed by our own perceptions so much as to possibly lose real information.
It is. And like the entry states, it is more or less a tautology. The universe is intelligible because we are intelligent. The Hawking chapter I linked to gives an excellent suggestion as to why that is so. However, cosmology would suggest that being anthropocentric isn't just a philosophical shortcoming, it is "natural."
Human-caused extinctions are fairly common, though I doubt that four-leaf clovers are endangered. But extinctions have been caused by other creatures too, if it is no more than a species being driven to extinction by another better adapted species, or by a predator species that hunts a certain kind of prey to extinction.
Unconscious nature is capable of sending a large asteroid or comet to wipe out 90% of the species on earth. It has done it before. This does not mean we shouldn't try to understand and live within nature's balance. But it does mean that we shouldn't be too proud or to guilty, about our manipulation of nature. Other things have manipulated it more.
You written this in a way that helps me better articulate the difference that I see and it pretty much centers on the notion of
intent. Nature doesn't really "send" astroids, at least I don't suppose it does. Astroids just happen to be around. Humans however can intend to inflict their will on astroids though. Again, it may be natural, but it is natural "once removed." Likewise, extinctions may be somewhat "natural" in the scheme of things, but what seems "unnatural" is any that human beings intend to create.
Further, the four-leaf clover analogy to me is an attempt to show how conscious ideologies could end up affecting nature in ways that just unconcious survival would not.
The idea that unnatural constitutes the inability to "break nature's laws" doesn't quite fit for me. For example, suppose we are able to genetically re-generate prehistoric life through preserved DNA... it's the stuff of Hollywood I realize, but not outside our current ability to research and plan for. If in fact, we are able to say create a T-Rex from mosquito blood encased in amber, then how "natural" is that really? It's not supernatural, but it certainly isn't natural.
Nature selected the T-Rex from existence. We re-introduce it while not having broken any real natural law. We
intend or choose to do X, Y, Z. It seems something like photosynthesis is necessitated by natural laws, while much of what we do is not. This intention of ours will grow stronger and more compentent as time progresses, provided we don't kill ourselves off first.
To me, this places us in a different place of natural order than say the dog or the dodo bird.
