Argument of the Law of Excluded Middle

In its manifestation, we encounter the notion of a third logical condition (an inclusion of measurements in concepts), often in the form of an attack on objectivity. A concept is coupled with a measurement and then erroneously used as its own concept. As an example, it could be asked how many grains of sand constituted a mound of sand with the implication that a single grain would not constitute a number. With such a worldview, it is difficult to answer questions like “What is the difference between a slap in the face and murder?” since we could not find clear boundaries between the concepts. Whenever we encounter an argument like this, we should discuss the underlying concept and not be fooled into arguing about the boundaries of the imprecisely defined concept.
