This is a word that is easy once difficult. Often we hear people say, you say not use logic. But the logic in this is the logic in the narrow sense, namely logic as a science which deals with public order thinking. Science is generally known through mathematics courses. But very little portion, probably less than 1%. Who studied computer science may be an additional portion of the logic of Boolean algebra again in the chapter. For most of us, the logic as a subject almost no imprint.
Logic indeed is a very basic art of thinking, which used to be, generally in the Middle Ages a very Aristotelean, the basis is very important for a person to become a scholar. Perhaps because the logic of science itself that it suffered a setback after the publication of Principia Mathematica, one of the last mathematical magnus opus, by Bertrand Russell and Alfred N. Whitehead, and direduksinya science into the simple logic boolean algebra which only deals with numbers 1 and 0 for computational purposes. Outside of computer science, logic may only be studied seriously in the department of philosophy.
Science of logic is an important part of a learning process. In the classical education, the science of logic learned in junior high school stage, which provides the basis for further development thinking in high school. Logic of science is taught in junior high school level is not with the logic in math, which is the modern logic. The logic given was traditional logic, the logic of Aristotle. Armed with logic, they can learn to think straight, logically, valid. They will not fall into the evils of thinking that a lot of us look at the people who said smart in the media. On the whole science of logic is quite broad, so it must be separated into separate subjects, outside mathematics, and is given at a junior high class. Unfortunately there is no traditional logic books are available in the Indonesian language is sufficiently clear to junior high kids can digest.
