# &quot;What is Logical&quot; In order to determine whether something is logical or not, one must have studied the basics of logic and understood it.

Introduction

Mia Buntic January 27, 2003 "What is Logical" In order to determine whether something is logical or not, one must have studied the basics of logic and understood it. It is not based on the mere fact that something would seem to make sense to a person, because each individual differs in though and understanding. What one might think is funny, another would consider rude. Therefore, in logic, there must be a set of rules, which would determine whether one's reasoning is correct or incorrect. If it were correct, it would be logical. This is where the difficulty and ambiguity of logic come in. How do we determine whether something is logical or illogical? Copi, like many others has studied logic and developed theories about it. According to him, logic is the study of the methods and principles used to distinguish good (correct) from bad (incorrect) reasoning. In order to do this; he establishes rules and methods of discovering whether an argument is valid. It is important to note the difference between truth and the validity of an argument. Truth and falsehood are applied to define propositions, but never the argument. The argument is defined as being valid or invalid. ...read more.

Determining the truth of propositions is easy, and many times irrelevant when it comes to logic. It is deciding whether an argument is valid or invalid that takes a lot of work. There are many ways to determine the validity of an argument in order to prove it logical or illogical. One of the ways is through fallacies. A fallacy is a type of argument that may seem to be correct, but that proves, on examination, not to be so. There are many different types of fallacies, which could prove an argument invalid and illogical. For example there is the fallacy ad verecundiam (Appeal to Inappropriate Authority) that arises when the appeal is made to parties having no legitimate claim to authority in the matter at hand. Here is an example of this: I say that all people who ride the train are poor people because when I talked to Bill Gates he told me that if a person rides the train then that person is poor. And I believe everything that Bill Gates says, so it has to be true that all people who ride the train are poor people. In this case, Bill Gates has no appropriate authority to determine whether a person is poor or not based on the fact that they ride the train. ...read more.

Conclusion

It is also important; however, to acknowledge that validity is not the only way to establish what is logical. In life there are many things, which could be argued, but there is not need to. For example: It is only logical that when a ball is thrown up into the air it will fall back down. This is due to the fact that there is gravity on Earth that will pull the ball down. When it is said that the ball will come down it is understood that gravity would pull it down and there is no need to form an argument and test its validity. This type of logic is acquired through experience. The more things one person sees, the more they will become accustomed to them and become familiar with their features, which they will consider logical. There are different ways in which a person can establish whether something is logical or not. There are the many definitions and formulas given in logic books that would allow a person to test the validity of an argument. This is a process, which requires a person to read and understand the material that is presented to them. The other way of determining whether something is logical is through personal experience. If one witnesses the same action numerous times, it is logical that they will become familiar with it and await the outcome. ...read more.

For better examples, we must move further forward in history, to the leaders in logical and rational thought- the Greeks. Over a thousand years before Galileo and Copernicus (at around 310 to 230 B.C.), Aristarchus of Samos suggested that the earth revolved around the sun, instead of vice versa.
