Overselling the Synthetic CellFATHER TADEUSZ PACHOLCZYK
In a May, 2010 article entitled "How We Created the First Synthetic Cell," Dr. J. Craig Venter waxes broadly about how his research team succeeded in constructing a bacterial cell out of its component parts.
The term "synthetic cell" suggests that they constructed the entire cell, brick by brick, molecule by molecule, from the ground up. What they really did was create a synthetic genome (a chemically manufactured copy of all the genes of a bacterium). This gigantic piece of DNA (a chromosome that happens to be the longest string of DNA ever assembled in the laboratory) was then placed inside another bacterium. Venter's group, rather than creating bacterial life out of nonliving matter, instead achieved the impressive technical feat of converting one type of bacterium into another when the new DNA was introduced. Venter himself, notwithstanding his previous attempts at self-promotion, stressed: "We definitely have not created life from scratch because we used a recipient cell to boot up the synthetic chromosome." His accomplishment, then, was to produce a large synthetic genome, not "synthetic life" itself.
Nevertheless, a number of commentators have managed to miss the point. Bioethicist Art Caplan, writing on the Scientific American website, suggests that Venter's "synthetic cell" dispels the notion that life "is sacred, special, ineffable and beyond human understanding."
Faye Flam muses in a similar vein in the Philadelphia Inquirer: "What's shocking about the new organism isn't that it breaches a boundary between inanimate matter and life, but that it shows that no such boundary exists. Life is chemistry." Her article gets even more outlandish when she suggests that chemicals "have the power to assemble themselves into organisms - even complicated ones that can contemplate their own place in the universe..."
Natalie Angier of the New York Times, meanwhile, is more measured and precise in summarizing Venter's work:
The Vatican newspaper L'Osservatore Romano, while noting how Venter's work is an impressive example of cutting-edge genetic engineering, also stressed that the researchers who created the cell had not created life, just "replaced one of its motors."
Even though Venter's work does not fundamentally alter our understanding of life itself, it does challenge us to reflect on our increasing technical ability to manipulate life and to dominate it. The arrogant suggestion that man should "create life" and the accompanying Promethean quest for power and fame through such endeavors should raise some alarm bells. Reducing life, even though it is non-human life, to merely another quantity that we control, exploit, and subject to market forces is to coarsen our sensibilities towards an important measure of our own being. In every living organism, whether humble bacterium, plant or animal, we encounter a faint glimmer of our own delicate life.
Professor Erwin Chargaff, who did pioneering work on the molecular structure of DNA, once commented in his rather biting style on the modern, almost condescending scientific attitude toward life:
Even as our ability to manipulate biological life in the laboratory continues to grow, the principle of life itself remains elusive and beyond our grasp. Living beings, with all their structure and complexity, should never cease to impress us and inspire us with a certain awe, so that even in our bated eagerness to harness their powers, we might avoid reducing life itself to a mere commodity or raw material for our biotechnical prowess to conquer.

The National Catholic Bioethics Center (NCBC) has a long history of addressing ethical issues in the life sciences and medicine. Established in 1972, the Center is engaged in education, research, consultation, and publishing to promote and safeguard the dignity of the human person in health care and the life sciences. The Center is unique among bioethics organizations in that its message derives from the official teaching of the Catholic Church: drawing on the unique Catholic moral tradition that acknowledges the unity of faith and reason and builds on the solid foundation of natural law.
Inspired by the harmony of faith and reason, the Quarterly unites faith in Christ to reasoned and rigorous reflection upon the findings of the empirical and experimental sciences. While the Quarterly is committed to publishing material that is consonant with the magisterium of the Catholic Church, it remains open to other faiths and to secular viewpoints in the spirit of informed dialogue.
Father Tadeusz Pacholczyk earned a Ph.D. in Neuroscience from Yale University. Father Tad did post-doctoral research at Massachusetts General Hospital/ Harvard Medical School. He subsequently studied in Rome where he did advanced studies in theology and in bioethics. He is a priest of the diocese of Fall River, MA, and serves as the Director of Education at The National Catholic Bioethics Center in Philadelphia. Father Tadeusz Pacholczyk is a member of the advisory board of the Catholic Education Resource Center.
