Important

Logic is very important in everyday life, it is related to our ability to reason. Luckily we as humans are given the ability to reason. So basically, all humans must unconsciously use their logic in living life. Logic comes from the ancient Greek word (logos) which means the result of consideration of the mind expressed through words and expressed in language. As a science, logic is called (science) which studies the ability to think straight, precisely, and orderly.

Science here refers to the rational ability to know and skill refers to the ability of reason to realize knowledge into action. The word logical used can also be interpreted as reasonable. In addition to the definition, logic is also often referred to as a "bridge" between philosophy and science which means a theory of valid conclusions. This valid conclusion is in accordance with rational considerations and is coherent so that it can be traced back which is also correct.

Logic can also be defined as a theory of inference based on a concept. It can be expressed in the form of words, terms, or sets. That is why in psychological tests or IQ tests there must be a part of the test that tests reasoning ability. So it measures how deeply and how well we use this reasoning ability. A statement that is often heard in everyday language, such as the reason is illogical, the argument is logical. All of these expressions are intended to refer to the same understanding, that logical is reasonable and illogical is the opposite, namely unreasonable.
