Introduction
The Straw Man fallacy is often committed by creationists in their defense of a literal creation by a supernatural agency when attempting to refute evolution.
This fallacy can be quite effective - if you are not on guard for it, or do not understand or aware of the opponents position.
Defined
Instead of representing the opponents argument accurately, the petitioner rephrases or misrepresents the oppositions argument as to make it easier to defeat. The petitioner then declares victory over this invented argument.
Therefore the allusion of a straw man. They are easy to knock down.
Example
According to his (Charles Darwin) evolution scenario, inanimate substances came together by chance to give rise to the first living cell.
---
"Living things did not come into being through the imaginary processes of evolution."
This example is from the Atlas of Creation by Harun Yahya. A Muslim creationist. Yes, thats right a Muslim creationist.
Like many creationists, Harun Yahya, restates evolution as a theory on the origin of life. Evolution is a theory on the origin of species. Meaning, Darwinian evolution starts after life begins.
Therefore, evolution can not account for abiogenesis. Because Yahya uses a straw man, it allows for an easy victory, despite the fact that it came at the expense of intellectual honesty.
In Conclusion
Straw Man arguments are an intellectually dishonest way of arguing against a position that one wishes to refute. The victory allegedly won is therefore useless.
Arguments and positions should be honestly confronted and then rejoined on the merits of the position, not one imagined.
