Why Study Logic? Perhaps the most important thing to give your child to prepare him to confront this world is a firm grasp of logical thinking skills. Without this refined skill — the ability to reason correctly — his thinking is not firmly anchored, but is "tossed to and fro, and carried about with every wind of doctrine." Children who can logically understand what they believe will hold fast to the truth and will be able to defend it throughout their lives.

Logic is necessary to analyze other people’s beliefs. Logical fallacies are everywhere in our society. If your child cannot detect the logical mistakes he hears, then how will he discern who is right? The study of logical fallacies (common mistakes in reasoning) is important to critically reason through the arguments of others.

Logic is necessary to understand and communicate our own beliefs. The Scripture commands us to prove our doctrines and practices. (Ephesians 5:10) We are to reason and dispute from the Scriptures with persuasive and convincing arguments (Acts 17:2) If we are able to think through and clearly reason from the Bible, then we will be better equipped to give a proper defense of our faith. (I Peter 3:15)

Logic is necessary. The study of formal logic should be considered foundational to every educational curriculum. In the past it was. The roots of logic stretch into every other subject. The construction and programming of computers, for example, is based entirely upon the application of the laws of logic. The proofs of algebra and geometry rely upon the laws of logic. The laws of logic, in one way or another, are fundamental to every academic discipline.

Unfortunately, the study of logic is dispensed with in the modern curriculum. Social skills are considered more important than thinking skills. Children do not learn to think for themselves. The study of formal logic will give your child life-long skill in proper reasoning. The study of logic should be considered indispensable...

...Logic Is the Master of Our Lives
Logic is the foundation upon which our lives depend. Each of us, moments after birth, begin our journey exploring the world around us in search of what’s real, or safe, or fun, or comfortable – a quest to sort out sense from nonsense. These skills expand as we grow, for understanding what’s real and learning how to extrapolate from what little we know as babies, are the fundamental tools of survival. We learn that reaching for an object and retrieving it gets us something we want. From this one concept we begin to develop our own logical model of the world around us. When we can reach a cup, we experiment with that cup. At first we can only feel it, then we may learn to move it and then one wondrous day we learn how to push it off the tray on to the floor and gleefully watch all the excitement that accompanies flying cup of liquid. As adults, we generally fail to share the wonderment, while cleaning up the experiment, but this is where the magic begins.
No one has explained logic to us, but by trial and error, and fascinating experimentation we began to know how the real world works. Logic takes care of itself; we only need to look and see how it does it.
Once we’ve mastered the art of spilling our milk, we inherently understand that the same thing is possible with orange juice, crackers, and baby food. Although we are far too young to understand the concept of...

What Is Logic?
1 Arguments
Symbolic logic is usually described as the study of the difference between valid
and invalid arguments, so we begin with an explanation of this terminology. An
argument is a piece of discourse which contains some premises, a conclusion,
and perhaps also some reasoning in which an attempt is made to derive the
conclusion from the premises. The premises are those statements which, for
the purposes of the argument, are being accepted as true. The conclusion is the
statement whose truth the argument aims to demonstrate, given acceptance of
the premises. Hence this ‘logical’ sense of ‘argument’ is quite different from its
sense in ‘Smith and Jones are having an argument’, though an argument in the
logical sense might be reconstructible from what Smith or Jones says.
For present purposes, we take an argument to consist just in a listing of the
premises, and then the conclusion. A valid argument is an argument whose
conclusion follows from its premises, and correspondingly, an invalid argument is an argument whose conclusion does not follow from its premises. Here
are two very simple arguments, one valid, the other invalid, which illustrate the
difference between the conclusion following from the premises and its not following:
A: (1) If our currency loses value then our trade deficit will narrow.
(2) Our currency will lose value.
(3) ∴ Our trade deficit will narrow.1
B: (1) If our...

Logic is the science and art of correct thinking and right reasoning. It is a science for it involves systematic and it utilizes theories, principles and laws governing human thinking and reasoning. And it becomes and art since it pertain apt theories, principles and laws leading to how human understand things and how they react to it not only in school but as well in actual life setting. Therefore, everything about it--- its definition, importance, and history must be studied.
The application of its theories, principles and laws to everyday thinking and reasoning helps minimize errors in our way of doing things such as making right decisions, choosing a career, organizing thoughts and sentences and many more. In general, what we do proceeds from what we think or from what we believe in. Thinking, which is said to be the best reference of logic, is associated with memorizing, remembering, imagining, guessing and day dreaming which are mental acts thus, making it one of the most essential ability of human living. Without logic, mind cannot reason out correctly. Our mind cannot ensue to certainty of right inference if we do not have proper knowledge about things and its processes.
At this crucial point of our lives as a teenager, being logical is one of the most important attribute to possess for it makes us responsible on how we act appropriately in our everyday lives. It let us shaped and expressed our...

WHAT IS LOGIC?
Logic may be defined as the science of reasoning. However, this is not to suggest that logic is an empirical (i.e., experimental or...

...different from it, in the sense there is checking and re - checking of the conclusion arrived at based on certain facts so reasoning is defined as '' a process of arriving at a new judgement on the basis of one or more judgement,'' Reasoning is the mental activity used in and argument, proof, or demonstration, reasoning is generally associated with rules and methods and formal laws of logic but many people reason and argue without being consciously aware of it. For example when a dog comes back after seeing the master enter his car, when we expect a letter from a friend or turn to the gate on hearing a noise. We are thinking and reasoning without realizing it.
Reasoning is a way of solving a problem or meeting a new situation, perception imagination and memory are closely related to reasoning for the help is assessing the situation and find out alternate solution of the problem.
Inference is the act or process of deriving logical conclusions from premises known or assumed to be true.[1] The conclusion drawn is also called an idiomatic. The laws of valid inference are studied in the field of logic.
Human inference (i.e. how humans draw conclusions) is traditionally studied within the field of cognitive psychology; artificial intelligence researchers develop automated inference systems to emulate human inference. Statistical inference allows for inference from quantitative data.

...Logic can be defined as the subject that teaches the rules for correct and proper reasoning or in simpler terms, it can be best described as common sense. Some refer to the "science" of logic but logic is really more than just a science. The science part "is the knowledge of the principles, laws, and methods of logic itself." (Dolhenty, J; 2002). Logic must be put into action or else the knowledge provided within the science of logic is of little use. "We can, therefore, also speak of the "art" of logic, that is, the practical application of the science of logic to our everyday affairs." (Dolhenty, J; 2002). Logic is not only intended to inform or instruct; it is also meant to assist in the proper use of our power of reasoning. As such, we can speak of logic as both a science and an art, a practical art meant to be applied in our everyday interactions.
Critical thinking is the method used when deciding rationally what or what not to believe. It can simply be described as the process for the use of reason in the pursuit of the truth. When thinking critically one must assess all assumptions for validity and appropriateness using our logic as a basis. Although the two concepts are closely tied, it is possible for a person to be logical but not be thinking critically. In this paper we will discuss the nature of...

...more to learn. Newton learned from Descartes, while Descartes learned from Aristotle’s work. Without knowing where it began, person can’t achieve true understanding of what’s new and what’s not. Moving forward in what’s known helps keep progress going forward.
Anaximander made several pivotal contributions to science but many of his theories have been discredited. He was one of the first people to try and map the known world (Barnes 18). Being able to show what was known during Anaximander’s time is extremely important. Historians are able to see the growth of the human mind. For his time, Anaximander was very intelligent. He had many theories about the known world, human origin, biology, and astronomy (Barnes 20). If historians didn’t study his text, the world would have never known he existed. The number of lost books and journals is countless. Historians only have a fraction of what is said to have existed. Doing the work now to sort and search will allow the scientific community grow and succeed.
By recording and researching all ancient historical text, historians are able to find out much more about our past than by just picking out what’s good and what’s not. Now, that the internet is a nearly limitless catalog. Humans must put in the work to preserve it. Time erodes nearly every single method of history records humans have. Cataloging scientific works should be a must and of utmost importance, no matter how invalid the subject or...
