In Issue 51 of Philosophy Now, Rick Lewis writes an editorial about why logic and philosophy are so vital:
Above all, the aim of studying the structure of arguments is to think more clearly. This is the aim of critical thinking. The idea is to look at the argument for some position, see if you can identify its precise logical form, and then examine that form to see where it might have weaknesses. ...
Just as philosophy in a sense underlies all other branches of human enquiry, so logic is the most fundamental branch of philosophy. Philosophy is based on reasoning, and logic is the study of what makes a sound argument, and also of the kind of mistakes we can make in reasoning. So study logic and you will become a better philosopher and a clearer thinker generally.
Thinking clearly is important to everyone every day of their lives. At least, it should be ó who wants to think un-clearly or incoherently? That should mean, however, that people would want to spend time learning how to think clearly and practicing so that they can improve. We donít really see that occurring, though, do we? Itís curious that something which is so fundamental to everything we do should occupy so little of our time and attention.
