Posted on June 22, by Gaz When we moved into our weed patch in Colorado, the one essential item missing was a place to store hay, keep our horses out of bad weather and keep our equipment dry. We had to build a pole barn! The cost of having some one build what we wanted was way out of of league — and so we decided to build our own pole barn.
The author is professor of biology, University of California, Santa Barbara. This article is based on a presidential address presented before the meeting of the Pacific Division of the American Association for the Advancement of Science at Utah State University, Logan, 25 June At the end of a thoughtful article on the future of nuclear war, Wiesner and York 1 concluded that: It is our considered professional judgment that this dilemma Simple essay on vegetables no technical solution.
If the great powers continue to look for solutions in the area of science and technology only, the result will be to worsen the situation.
An implicit and almost universal assumption of discussions published in professional and semipopular scientific journals is that the problem under discussion has a technical solution.
A technical solution may be defined as one that requires a change only in the techniques of the natural sciences, demanding little or nothing in the way of change in human values or ideas of morality.
In our day though not in earlier times technical solutions are always welcome. Because of previous failures in prophecy, it takes courage to assert that a desired technical solution is not possible.
Wiesner and York exhibited this courage; publishing in a science journal, they insisted that the solution to the problem was not to be found in the natural sciences. They cautiously qualified their statement with the phrase, "It is our considered professional judgment.
Rather, the concern here is with the important concept of a class of human problems which can be called "no technical solution problems," and, more specifically, with the identification and discussion of one of these.
It is easy to show that the class is not a null class. Recall the game of tick-tack-toe. Consider the problem, "How can I win the game of tick-tack-toe?
Put another way, there is no "technical solution" to the problem. I can win only by giving a radical meaning to the word "win. Every way in which I "win" involves, in some sense, an abandonment of the game, as we intuitively understand it. I can also, of course, openly abandon the game--refuse to play it.
This is what most adults do. The class of "No technical solution problems" has members. My thesis is that the "population problem," as conventionally conceived, is a member of this class.
How it is conventionally conceived needs some comment. It is fair to say that most people who anguish over the population problem are trying to find a way to avoid the evils of overpopulation without relinquishing any of the privileges they now enjoy.
They think that farming the seas or developing new strains of wheat will solve the problem--technologically.
I try to show here that the solution they seek cannot be found. The population problem cannot be solved in a technical way, any more than can the problem of winning the game of tick-tack-toe. What Shall We Maximize? Population, as Malthus said, naturally tends to grow "geometrically," or, as we would now say, exponentially.
In a finite world this means that the per capita share of the world's goods must steadily decrease. Is ours a finite world? A fair defense can be put forward for the view that the world is infinite; or that we do not know that it is not.
But, in terms of the practical problems that we must face in the next few generations with the foreseeable technology, it is clear that we will greatly increase human misery if we do not, during the immediate future, assume that the world available to the terrestrial human population is finite.
A finite world can support only a finite population; therefore, population growth must eventually equal zero. The case of perpetual wide fluctuations above and below zero is a trivial variant that need not be discussed. When this condition is met, what will be the situation of mankind?
Specifically, can Bentham's goal of "the greatest good for the greatest number" be realized? No--for two reasons, each sufficient by itself.
The first is a theoretical one. It is not mathematically possible to maximize for two or more variables at the same time. This was clearly stated by von Neumann and Morgenstern 3but the principle is implicit in the theory of partial differential equations, dating back at least to D'Alembert The second reason springs directly from biological facts.Learn why your family should eat plenty of fruits and vegetables every day.
