We might never have made it

Lately I’ve been perusing Leon Kass’s book Toward a More Natural Science. Most recently, I read the chapter on prenatal diagnosis which begins with this excerpt:

The chapter you are about to read might never have been written. The same, of course, could be said about any work of writing, for the usual and obvious reasons—not least, because the author might never have been born. But for the present author and the present readers of the present chapter, the accident of our births may now be seen to have been more than usually accidental. Reflect a moment, gentle reader, and take stock of yourself: I suppose that you, too, will discover how fortunate we are to be here. For we were conceived after the discovery of antibiotics yet before amniocentesis, late enough to have benefited from medicine’s ability to prevent and control fatal infectious diseases, yet early enough to have escaped from medicine’s ability to detect, and to prevent us from living to suffer, our genetic diseases. To be sure, my own genetic vices are, as far as I know them, rather modest, taken individually—myopia, asthma and other allergies, bilateral forefoot adduction, bowleggedness, loquacity, and pessimism, plus some four to eight as yet undiagnosed recessive lethal genes in the heterozygous condition—but, taken together, and if diagnosable prenatally, I might never have made it.

After antibiotics and before amniocentesis – this is the in-between we who are alive today straddle.

Kass makes obvious in this paragraph that preventing people from suffering can go so far as to prevent them from living.

Many have a lower threshold for what suffering they will tolerate for others compared to what they could endure themselves. This is something worth bearing in mind whenever we hear words like “intolerable” and “unbearable.” What we ourselves cannot bear or tolerate cannot be the standard for evaluating others’ quality of life.

After all, one of the best qualities of life is the way it continually surprises us.
