As defined here: http://skepdic.com/falsedilemma.html
The false dilemma (or false dichotomy) is a fallacy of reasoning that omits consideration of all reasonable alternatives. Sometimes called the either-or fallacy, one poses what looks like a true dilemma--I must pick one or the other--when, in fact, there are other viable alternatives. (There can be false trilemmas, etc.)
This is becoming increasingly common in JW literature. The February Awake (cover article: Earth - Designed for Life) is full of them.
The approach is very formulaic:
1) Present some marvelous feature of nature
2) Present the question "Did this come about by blind chance, or was it Designed by a Loving God?"
This sequence is presented 4 times in the 7 pages of the series of articles. It is presented numerous more times in the book "Is There a Creator Who Cares About You?"
Of course, the problem is that no reasonable educated person, anywhere, ever makes the claim that anything related to nature arose from "blind chance". There are more than just those 2 options. But the WT is counting on the ignorance of its readers in not recognizing that.
Incidentally, it's not just JWs who use this technique. It seems to be a favorite of fundamentalist Christians everywhere. In our local paper, there is an "advice column" ghost-written in the name of Billy Graham. Yesterday's topic was on "Is there really a devil?" The answer said, in part, "it takes far more faith to believe that all of the evil in the world arises from chance than from the devil."
Umm, hello? Who says those are the only 2 options?
Even C.S. Lewis fell into the trap, regarding Jesus:
Either this man was, and is, the Son of God, or else a madman or something worse...
At the risk of being annoyingly repetitive, hello? Who says those are the only choices?
