When constructing an argument, the person must come from a logical perspective. In doing so, individuals must understand “the basic principles of logic”. According to D.Q. McInerny, in her book Being Logical, there are four principles of logic. This includes, the principle of individuality, the precept of the excluded middle, the principle of sufficient understanding, and the principle of contradiction. Along with the principles of logic, the language of logic should be taken into account with arguments. The principle of identity entail’s “things” to be distinguishable from other “things”. Essentially in the aspect of identity, a cat is a cat. That cat cannot be anything other than. It is not a dog, a bird, nor is it a snake. Aside from identity, …show more content…

From here an individual, then must understand the language of arguments in order to construct it appropriately. McInerny stated in Being Logical, “The concrete expression of logical reasoning is the argument. An arguments stands or falls to the extent that the reasoning it incorporates is good or bad (page 47).” Constructing an argument must include, “the inferential move” which is described as when we go from one idea that is known to be true to a second idea that is recognized to be true on the basis of the first idea. Arguments are broken into three different forms.
Conjunctive Argument: Two conclusions that may be verbalized differently, but are rightful. The isolation of one term as true and the other false cannot occur within conjunctive argument.
Disjunctive Argument: A statement that carries two elements with mutual exclusions cannot both be concluded as true. One is true while the other is …show more content…

In answering this, arguments may be built in a number of ways depending on the kind of argument being given. According to rationaleonline.org, Simple parameters are the most basic units of logical thinking. Discusses various forms, their functions, and how to represent them. Simple Argument Structure looks in more detail at the internal structure of simple arguments also giving simple guidelines for identifying assumptions and seeing to it that the whole thing hangs together right. Multi-Reason Arguments studies arguments in which more than one reason or objection bear upon an individual title. It discusses some common errors in mapping such arguments. Multi-Layer Arguments gives reasons or objections that are supported or opposed by further arguments. This band extends the principal varieties of multi-layer parameters, how to map them, and how to avoid some common mistakes. Inference Objections are a variety of multi-layer parameter, and mapping them is specially challenging. This set shows how to map inference objections as objections to hidden premises. Lastly, macrostructure is the social organization of complex arguments on a large plate. This band covers some fundamental rules for creating maps of well-structured complex
