Mighty mouse?

Scientists modify a mouse gene to create a super-active, super-long-lived, super-healthy mouse.

My questions:

1. Do we actually want to live twice as long?
2. Do we actually want to be seven times as active? Can you imagine what that would do to human society?
3. As the article rightly points out, this has to do something to the mice’s brains. What might it do to ours?

The real battle

WARNING: What follows is going to be a pretty bitter rant. Let me qualify everything I may say (since I won’t have time to edit it) with this: no, I have not lost my faith. I am still every bit the traditionalist, pro-life, wholeheartedly believing Catholic I was. I’ve simply seen too much in the past few days to believe that we’re having any success whatsoever at reaching those who need us more than anyone else: the poor.

————————

We’re fighting the wrong battle. Abortion is so visible; it attracts so much attention; but, it’s a wicked feint. We’re like French soldiers haplessly manning the impregnable Maginot Line while the Germans, ruthlessly efficient, simply marched around. We feel so good praying our Rosaries in front of abortion clinics; we might even spend time showing others the horrors of “termination” with graphical photos of dismembered fetuses. We donate to pro-life causes; we volunteer at agencies that promote support of pregnant women. We really do make a difference.

But for every person we help lead back to a culture of life, we lose countless others who fall victim to the ultimate modern seduction. It goes by a simple name; it is a simple ploy; and unfortunately, it works. It’s called the Pill, and it may be the Enemy’s perfect weapon.

Think about it: what else can you procure that will instantly divest you of any responsibility for anyone but yourself? Just take a pill every day (or even better, a shot every three months or a patch every week), and you no longer have to worry about kids interrupting your pleasure. It’s no wonder that the vast majority of poor Hispanic women, of whom a large number are nominally Catholic, fall for it. Why have a brood of children when you can have sex with your boyfriend (and why bother to get married for that matter?) with impunity?

And yes, there are consequences to this libertine mentality. Sexually-transmitted diseases are rife. But there’s another subtle aspect to this sabotage of fertility: an often warranted faith in the infallibility of modern medicine. If we do get sick, the doctors can fix it. What’s scary is that, in many cases, we can.

So, on the one hand, we have the Catholic ideal: accepting the God-given gift of marriage and fertility, loving children as we procreate them, supported by a community–a Church–that makes the raising of future faithful generations possible. It’s an incomparably beautiful vision–but it relies upon self-denial. On the other hand, we have the modern ideal: planned parenthood. Sex is for your pleasure only; if you want to, you can let it follow its “natural” course to produce children; if you don’t, it’s not a problem. Hedonism rules under the guise of liberty, and self-denial is the ultimate evil.

Look at the evidence and tell me which of these two visions is winning the hearts of the one group of people that we are commanded above any other to serve: the poor. We well-catechized Catholics can see the beauty of the culture of life–and even we, if we really look into our hearts are seduced to some extent by the other side. Imagine those who do not know their Faith–those who often simply struggle from day to day to make ends meet. They are provided–usually for free, by our health care system–access to the modern vision of freedom. We Catholics, on the other hand, offer an alternative that is costly. Beautiful and true, yes, but at a price that most people today are unwilling to pay.

So what can we do to stem what I’ve described as an inexorable tide? I really don’t know, but here are some thoughts.

We have failed first and foremost in community. If a woman has a child in an adulterous relationship, we should step and help her to take care of him. If she can’t, then we should take the child in. We must, for our own souls’ sake, rely upon others of like commitment.

We have also been failed by our priests. If Father neither preaches from the pulpit nor counsels in private that contraception is a problem, then the message is obvious: that it’s OK. Even worse, if he actively counsels his flock in private (or in public) that it’s OK to contracept and have sex outside of marriage–and I know this happens in our parishes daily–there is no way we will be able to convince people otherwise. Especially not in a hierarchical Latin-American society where the padre, for some reason which escapes me, still commands a vestigial position of authority. Our pastors must be men of faith who preach and practice what the Church teaches. Yes, they are human and they will sin, but that does not change the Truth they proclaim.

And we have failed, and will continue to fail, individually. Original sin still haunts us and will continue to do so. So, in the end, despite my bitterness, I am compelled to write that there indeed is hope. We are not intrinsically different from our fathers; they failed but the possibility of life eternal continues. We should pray; we should start attempting to rebuild, on a small scale at first, the communities, pastored by good priests, that make living the Catholic life possible. It was possible before despite our sinfulness; it is still possible. Maybe, as Alasdair Macintyre suggests, we do need a new St. Benedict to lead us into the desert and teach us to purify our souls.

We rightly fight the evil of abortion, but by all means, we mustn’t lose sight of the real battle.

And I thought mandatory health care was bad

Now, the Conservative Party in the U.K. is proposing that care be denied to people who don’t stop “unhealthy lifestyles.”

Do they really think that’ll cause people to change? I once saw a patient who had had half of his larynx and a lobe of his lungs taken out on separate occasions for lung and larynx cancer, and still smoked a pack a day. Such disincentive might lead to some people eating healthier and stopping smoking, but for everyone that does that, five will end up sicker or dead from lack of care.

Mandatory health care?

Heaven help us if John Edwards becomes president. I think I might actually pull for Hillary.

What a spectacularly bad idea: mandatory preventive care. I don’t even know where to begin. On the surface, it makes some sense. A substantial percentage of our GDP is spent on health care that would not be necessary if folks took better care of themselves. Some part of that would be reduced if diseases were caught early and corrected. To make people go to the doctor would lead to physically healthier lives. But at what (non-monetary) cost?

Stay tuned. I have some time to post for once….

Misunderstanding evolution

I’m not a paleontologist, nor do I know all that much about speciation, but this Yahoo news piece on human evolutionary origins needs a bit more thought…

New discoveries by Maeve Leakey have dated Homo habilis and Homo erectus specimens to the same period that were found within walking distance of each other. The conclusion reached in the news article is that, therefore, the latter is unlikely to have evolved from the former. Sounds logical, right? Two species that live at the same time can’t be descended from each other.

Well, there is absolutely no reason why an older species can’t remain while a younger species develops. Here’s one example of how: suppose that, due to environmental factors, one group of animals gets separated from a larger population. This group then, because it is isolated (for whatever reason) from the other, diverges to the point that it is no longer the same species. Then, at some later point, members of the new group travel back and live among the original population (that, because its environment hasn’t changed, hasn’t “evolved” all that much).

When we, millions of years later, look at fossils from the area where the two groups then lived, it’s easy come to the same conclusion as the folks in the news article. These two groups couldn’t have come from one another because they lived together at the same time. But, at an earlier point, they might not have.

It’s scary how easy it is to come up with explanations for historical discoveries (like those in paleontology) using evolutionary theory. (Is the theory, in fact, falsifiable? I’m not so sure.) But, it’s equally scary how easy it is to grab a hold onto any data that seems contradictory to evolution, and bank on it to boost creationism…

When humanity and homo sapiens clash

I should be studying (as always) before heading off to Latin Mass this afternoon, but I had an odd series of ideas yesterday that need hashing out in words. This is what tends to happen when I have a couple of days off from the ridiculously hectic schedule of medicine….

We’ve spent the past 148 years trying to work out the ramifications of Charles Darwin’s dangerous ideas. If all the living creatures around us are the products of natural selection, then, likely, so are we. The mechanism behind the variation which enables nature to select for the fittest is simple enough: changes in DNA produce changes in proteins that result in changes in function. These changes are almost always deleterious, but at least theoretically, a change in protein structure could enhance efficiency or produce new functions. Over time, as creatures encounter changing environments and compete with each other, various changes in their genetic material are selected for and maintained down the generations. It’s an elegant theory, one that can explain how the vast array of biological life came to be. Yes, it has problems, particularly with explaining large-scale changes and speciation, but I’m not interested–at least not in this essay–in exploring the whole evolution-vs.-creation controversy.

But what about the timescale of evolution? How fast can things biologically change? Organisms with short generation times or error-prone genetic replication systems can evolve remarkably rapidly. Take, for example, the production of antibiotic resistance in bacteria. Or, if we consider viruses to be alive, the champion evolver is the constantly changing HIV virus that stays one step ahead of our immune systems. A bacterial species that doubles in number every couple of hours can adapt genetically to almost any environmental change. But what about us? Our 70+ year life expectancy and long generation times mean that it would take thousands of years to produce the same changes that bacterial populations undergo in a matter of days. Are those changes possible? Sure. They’re even likely.

However, mankind throws a wrench into the mechanism by being creative. We think, ponder, discover, invent at a rate that far surpasses generational genetic changes. While Cro-Magnon Man and I are, on a genetic and biological level, essentially identical, our worlds are radically different, not because of biological evolution, but because of our abilities as sub-creators. Our bodies cannot keep pace with our minds–especially not with the rapidly accelerating rate of technological change over the past hundred years. What ramifications might that have? There are countless possibilities: I’ll focus on a few.

The human body, for all the vast array of diseases to which it is subject, is a finely tuned machine. Left to its own devices, it is fairly good at healing itself and fighting off any number of microscopic and macroscopic invaders. We creators think we can enhance things, though. Sometimes we can, but not without unforeseen consequences. Why is it that there is an epidemic of allergies and autoimmune diseases in the developed world? I pin the blame on two advances: hygiene and immunization. Would I take either of those back? Of course not, but our immune systems, from a biological angle, are intended to combat bacteria, viruses, fungi, parasites, etc. If we have a lower burden of those, I suspect that immune cells have a higher chance of attacking things that they shouldn’t–like things in our own bodies–or are hypersensitive to external things that shouldn’t be a bother–like cat dander. I wouldn’t trade millions of bothersome allergies for millions of deaths from infection, but the principle holds: we’ve short-circuited a slow evolutionary process and have to face the reality that our bodies react to our creations in less than ideal ways.

Allergies and autoimmunity are physical examples of what happens when we meddle with our biological selves, but what about the costs of modern technological society on a more abstract level? I have, as usual, more questions than answers. Is our modern plague of depression, anxiety, and mental illness the result of, quite simply, not having to deal daily with what our ancestors bravely faced: death or survival? Are we consumed with ourselves because we’re insulated from stark reality? Do we fear death more, and as a result quixotically seek physical immortality, because we can push the reality of our mortality out of our minds for extended periods of time? Are we losing belief in God because we surround ourselves with our own creations? Has our incredible store of knowledge about things led to a paradoxical loss of understanding of ourselves?

The problem is the same whether you believe that we are the special creations of God or the result of millions of years of evolution–or both. It is undeniable: we biologically cannot adapt at the same pace at which modern human society is changing. Genetics won’t allow it. We’re cavemen in modern garb (with apologies to Geico). Does that mean I want to turn back the clock and return to the Stone Age? Far from it. Modern medicine and science have changed our lives for the better. But we ought to step back and think about why we react as we do to modernity. Look beyond the technology that surrounds us to the fact of death. Look past the anxiety that can consume us and accept that, despite appearances to the contrary, we really can’t control everything. We have just postponed and disguised the inevitable by our creations. Know thyself, not just the world around.

Quote of the day

All things were made to lead us to God. As a matter of fact, though, most things turn us away from him. The only puzzle to be solved is to make the things which turn us away from God become means to lead us to him. … It is we, by the bad use we make of things, who render them blockades between him and us. There is therefore no other problem than to transform these very same things, the things that make up our daily lives, from obstacles into means. And it is there, then, that our temporal activities, our work in the world, become the very material, we might say, for our practice of the spiritual life–means for going towards God. At that moment, we shall have caught on to the unity of our life. A day that can be spent in the most total banality, taken up by the purely human aspects of work, and bringing me in the evening only a kind of frightful void–it is up to me to transfigure it by a miracle of the heart and to invest it with a kind of incorruptible substance.
