I'm sure most of us would claim to be open-minded. In fact, most people I've spoken to would consider it an insult to be called "closed-minded". Well, I'm going to put everyone's open-mindedness to the test, with this thread. (BTW, I would like to give credit for this thread to Manuel_Silvio. I've opened my mind greatly, after having debated with him for many posts). Philosophy, Science, and Mathematics all hinge on one thing: Logic. One must believe that there is some logic to the Universe's behavior, in order to be in any of those fields. However, have you ever considered the possibility - left open by logic itself - that the Universe does not behave logically? I'm not saying that I believe that the Universe is illogical, I just think it's a good idea to open our minds to the possibility. Why? Because there is nothing logically conclusive to cause one to tend toward logic. For example, Inductive reasoning is to try an approach as many times as possible, and then make a conclusion, based on empirical patterns observed (correct me if I'm wrong about that, btw). However, common sense will tell one that Inductive logic cannot be trusted; as one can never try something an infinite amount of times. This means that everything that we have observed to be an empirical pattern could just as easily have been a coincidence, every time. I welcome any argument/correction/comment/etc, that anyone would care to provide. I also wish to remind you all that this post is not intended to invalidate logic (as one could not "logically" do so ). No, it is intended to open one's mind to the fact - that, through ignorance, we "knew", when we were young children - that logic is not essential, provable, even demonstrable (if one's mind is open enough).
