The Structure of Scientific Thought

Science 240

Fall 2002


Homework #3

Due Friday, November 8th.

Write a 250–300 word essay (about one full typewritten page, double spaced) on the following topic:

Proponents of intelligent design creationism claim that it is a good scientific theory and is a reasonable scientific alternative to evolutionary theory. Using one or two of the criteria for evaluating scientific theories that have been discussed in class and the readings (e.g., agreement with data, testability, simplicity, fruitfulness, explanatory cooperation, entrenchment, etc.), evaluate this claim. Do you agree that intelligent design creationism is a good scientific theory? Why or why not?

In your introductory paragraph, provide a clear, recognizable statement of the thesis that you will be defending, i.e., tell us whether or not you think intelligent design is a reasonable scientific alternative to evolutionary theory. This is the conclusion of your argument.

Present a clear statement/explanation of one or two widely used criteria for choosing among scientific hypotheses. You will use these criteria to justify your conclusion.

Present an argument in favor of your thesis. Your argument must show how the criterion or criteria for distinguishing among theories you chose leads you to conclude either that intelligent design is a reasonable alternative to evolutionary theory or that it is not. Your argument should be as detailed, specific, and concrete as possible. For example, you might provide a detailed critique of the testability of evolutionary theory (suggesting that intelligent design theory is a reasonable alternative to evolutionary theory), or you might argue that the theory of intelligent design does not cohere well with existing scientific knowledge in a wide variety of other fields (suggesting that intelligent design is not a reasonable alternative to evolutionary theory).

Hint: Don’t even attempt to cover all aspects of the issue.  Be focused. It’s better to cover one idea well than a lot of ideas poorly.

Grading Criteria:

  1. How well you follow the instructions above.

  2. Accurate knowledge of the appropriate course material.

  3. Logical strength of your argument. Remember, you are trying to convince the reader of the plausibility of your thesis. Your college friends should be able to understand your argument and be impressed with it.

  4. Insight, independence of thought.

  5. Clarity of the writing, logical organization of the paper.

  6. Points will be taken off for too many spelling and grammatical errors.
