The Fallacy of Irrelevant Thesis

Posted on Jun 1, 2011 in Logical Fallacies

The straw-man argument can be considered a sub-class of the Irrelevant Thesis. This is when someone attempts to prove a conclusion that is not at issue. For example the evolutionist may say “Why is the universe ideally suited for life? Because otherwise we wouldn’t be here to observe it”. It is true that if the universe were not suited for life we wouldn’t be here to observe it but this does not actually answer the question WHY the universe is suited for life!
