Formal Logic looks like a colossal and magnificent building with blocks put one on the other carefully. But Formal Logic that only considers "forms" of consciousness in a standstill world of objects. For this, Identity Principle stands as the pivot of Formal Logic. But, if thought-objects reflect real objects in the objective world logic cannot be satisfied with this picture. Even in daily life, when you probe a worn-out object, for example a pen or a watch or something else, and you cannot easily decide whether it is usable or should be discarded nand your thought sways between calling the object "A" or "B" you have no choice but apply dialectic to the object because the real changing object is in a dialectical process. Doubt, in this sense, is the product of confrontation between dialectically thinking man and moving object. So, Formal Logic may be defined as the logic that deals with end-points when things are at rest. Of course, things at rest are subjective and irrelevant to the real world.
