with only three categorical standard form propositions. The inconsistency of the square of opposition thus appears. When a true argument is at the bottom of the chart, while a false statement is at the top of the chart, therefore only the actual meaning of the contradictory claim isspecified. The remaining three claims remain unclear. Although we use the square of opposition, we can not completely decide whether a claim can be true or false at times. The square of opposition has certain restrictions, and this reasoning can not function under certain conditions. (The Square of Opposition: A Cornerstone of Thought, 2020)In conclusion, defying arguments in categorical logic and square of opposition are helpful. With categorical logic we are able to learn and define the various types of relations and groups between these categories: A, E, I, O. When using the square of opposition, which is a diagram that allows us to decide whether a proposition is true, false, or undetermined. (Parsons, 2017). In fact, when evaluating a patient conditions, they are critical in the nursing profession. For example, if a patient states he is allergic to all products with peanuts, we could not presume that he is not allergic to some products containing peanuts, since he means ALL. Therefore, we must keep a closer eye on his diets. If we learn how to assert and refute claims based on categorical logic and square of opposition, as critical thinkers and future nurses, we know what is the right approach and can take appropriate measures for our patients.
