How to Write an Essay Introduction (with Sample Intros)
First, admit that it is impossible to say or do or writeanything that will interest everybody. With that out of the way,the question then becomes: "What can a writer do that will securethe interest of a fair sized audience?"
How to Write an Essay Introduction
If we really thought that genetic information was like the signal in Contact, shouldn’t we infer we were designed by extraterrestrials? Intelligent-design theorists do sometimes mention extraterrestrials as possible suspects, but most seem to have their eyes on a designer more highly placed in the heavens. The problem is, science requires a specific model that can be tested. What exactly did the designer do, and when did he do it? Dembski’s nebulous hypothesis of design, even if restricted to natural processes, provides precious little that is testable, and once supernatural processes are wedged in, it loses any chance of testability.
But how do we know that nature requires no help from a designing intelligence? Certainly, in special sciences ranging from forensics to archaeology to SETI (the Search for Extraterrestrial Intelligence), appeal to a designing intelligence is indispensable. What’s more, within these sciences there are well-developed techniques for identifying intelligence. Essential to all these techniques is the ability to eliminate chance and necessity.

Scientific theories, however, must fit the evidence. Two examples of the evidence for Darwin’s theory of evolution — so widely used that I have called them “icons of evolution” — are Darwin’s finches and the four-winged fruit fly. Yet both of these, it seems to me, show that Darwin’s theory cannot account for all features of living things.

Most introductions begin with an orientation in the form of a brief general statement that leads the reader into the topic showing how the specific topic relates to bigger issues or to the discipline field.

In my book The Design Inference, I argue that specified complexity reliably detects design. In that book, however, I focus largely on examples from the human rather than the natural sciences. The main criticism of that work to date concerns whether the Darwinian mechanism of natural selection and random variation is not in fact fully capable of generating specified complexity. More recently, in No Free Lunch, I show that undirected natural processes like the Darwinian mechanism are incapable of generating the specified complexity that exists in biological organisms. It follows that chance and necessity are insufficient for the natural sciences and that the natural sciences need to leave room for design.

Intelligence leaves behind a characteristic trademark or signature — what I call “specified complexity.” An event exhibits specified complexity if it is contingent and therefore not necessary; if it is complex and therefore not easily repeatable by chance; and if it is specified in the sense of exhibiting an independently given pattern. Note that complexity in the sense of improbability is not sufficient to eliminate chance: flip a coin long enough, and you’ll witness a highly complex or improbable event. Even so, you’ll have no reason not to attribute it to chance.
Do not flatly announce what you are about to do in an essay
Behe’s contention that each and every piece of a machine, mechanical or biochemical, must be assembled in its final form before anything useful can emerge is just plain wrong. Evolution produces complex biochemical machines by copying, modifying, and combining proteins previously used for other functions. Looking for examples? The systems in Behe’s essay will do just fine.
