We’ve said that arguments are what philosophers use to establish their conclusions and that the reliability of arguments depends on two things: their structure and their premises. We split arguments into two types and gave them posh names (deductive & inductive) and noted the sorts of conclusions that each can give rise to (certain and highly probable respectively).

Now, moving on we need to look at arguments that contain mistakes and think about how we might be able to spot them. And as we do this it’s a bit of a good news/bad news situation. The good news is you learn almost everything you need to know with some flashcards (available on this blog) or something so if you okay at memorising you’re cruising. The bad news is that (as ever) philosophers use lots of technical words in this area and also, if you took philosophy to avoid maths, this section has a tendency to end up a bit ‘equationy’. The first new word is ‘fallacy’. In philosophy a fallacy is a posh way of describing an error in reasoning in one word. Okay so far? Here are the two different types…
