As we all love a good debate on this site I thought it might be handy for us to have an idea of some of the tactics we all often use (mostly unintentionaly) to try to win a debate, but which aren’t actually useful at all, and in fact do not prove our points one little bit. Logical fallacies keep us thinking we have arrived at the truth when in reality we have done no such thing. This page and its contents will hopefully help each of us recognise logical fallacies in others arguements as well as our own and help us to be rigorous in presentating our arguments and premises.
A logical fallacy is, roughly speaking, an error of reasoning. When someone adopts a position, or tries to persuade someone else to adopt a position, based on a bad piece of reasoning, they commit a fallacy. I say “roughly speaking” because this definition has a few problems, the most important of which are outlined below. Some logical fallacies are more common than others, and so have been named and defined. When people speak of logical fallacies they often mean to refer to this collection of well-known errors of reasoning, rather than to fallacies in the broader, more technical sense given above.
This is the brilliant site, that contains an encyclopaedia of Logical Fallacies or you can click on the image below to view a great graphic depicting the a good, albeit smaller list.
From here on in, whenever we see a logical falacy in peoples arguments we can look up that fallacy HERE and provide the poor delusoinal thinker with a link to thinky awesomeness!
