The exactness of inductive logic is uncertain, therefore, it uses different properties to develop a conclusion, even though the conclusion is probably not completely correct. While on the other hand, deductive reasoning can lead to a completely correct conclusion only if the properties that lead that conclusion are also correct.
Deductive logic is logic where genuine properties mature a correct and rational interpretation. This kind of logic interpretation has to be correct, and it uses general guidelines to construct a detailed conclusion. It begins with an original statement, or assumption, then research the chances to achieve a detailed judgement. This form of analysis starts at a usual, theoretical stage, and then works its technique down to a more precise and solid stage. With this kind of logic, if something is establish to be correct for a variety of items, then it is established correct for all items in that group in general.

Syllogism is a type of rational argument that involves deductive logic to reach at a conclusion formed on at least two arguments that are stated or presumed to be correct. Syllogism has two properties, an important and an unimportant phrase, that must be assumed to be correct, and a conclusion. Syllogism suggest to something quantifiable, therefore consists of words such as, all, some, and other similar words. For example: All cars have wheels. (Important property) I drive a car. (Unimportant property) My car has wheels. (Conclusion). There are also four potential types of argument in a syllogism. For example: worldwide agreement (all women are human). Specific agreement (some adults are Christian). Worldwide contradictions (men are not humans). Specific contradictions (some adults are not
In this argument, if “employees have a duty of loyalty to the companies that employ them” is considered the p and “it is rational for employees to expect companies to recognize and fulfill a duty of loyalty to their employees” will be the q. It continues to follow that q is false as it is not rational for employees to expect companies to recognize and fulfill loyalty to their employees. The logical form ends with not p as “It is false that employees have a duty of loyalty to the companies that employ them”. It is known that this argument is deductively valid but in order to show that the conclusion is also true, it must be true that the argument is deductively sound. An example of a deductively valid argument would be as following: Premise 1) All mammals have four feet; Premise 2) Lions are mammals; Conclusion) Therefore, Lions have four feet. Premise 1 in this argument is true, mammals do have four feet, Premise 2 is also true, Lions are mammals, and therefore the conclusion is also true that Lions have four feet. With these true premises leading to a true conclusion help us understand
Ackermann, in the Preface to his Modern Deductive Logic, takes quite a different approach. He emphasises the "mathematical and scientific applications" of symbolic deductive logic, but says "one may well wonder" whether it has "enough philosophical value" to justify a major place in the philosophy curriculum.
Stephen Toulmin noticed that good realistic arguments consist of six actual parts. The extended method includes claims, data, and warrants, but it includes backing, qualifications, and a rebuttal, which are used to test the authority of a given warrant. The backing takes the warrants and adds additional evidence and reasoning to validate the warrant. With backing a warrant, there must be a way of qualifying statements expressing the degree to which the speaker defends a claim or to limit the strength of the argument to its truth. There is never just one view or one side of an argument, there are counter-arguments or statements called rebuttals that indicate the circumstances when the general argument does not hold true.
According to traditional syllogistic logic, which has its roots in Aristotle, there are four types of propositions: the A proposition ("All S are P"), the E proposition ("No S are P"), the I proposition ("Some S are P"), and the O proposition ("Some S are not P"). These propositional types represent all of the possible combinations of the dichotomies of affirmative/negative and universal/particular. Each makes a claim that a certain essent (the particular I and O propositions) or an entire class of essents (the universal A and E propositions), the subject or subject-class, relates in some way (belongs or does not belong) to a class of essents designated by the predicate of the proposition. The traditional, or Aristotelian, standpoint for evaluating the truth or falsity of these propositions assumes that each class designated by a term in the subject and predicate actually exists. This allows certain conclusions to be drawn regarding the relationship between the truth values about different types of propositions, and these relationships are symbolized visually in a diagram called the "Traditional Square of Opposition." (These relationships are designated as "contradictory," "subalternate," "contrary," and "subcontrary.") The modern, or Boolean, interpretation of Aristotle's syllogistic logic, however, makes no assumptions about the existence of the classes denoted by the subject and predicate terms of a proposition. Because of this, there are fewer conclusions that one is able to draw about the relationships between the truth-values of different propositions. (The only relationship on the modern square of opposition is the relationship denoted by the term "contradictory....
The problem of induction has a close relation with the inductive reasoning and such expression as “a posteriori”. There are two distinct methods of reasoning: deductive and inductive approaches. A deductive argument is the truth preserving in which if the premises are true than it follows that the conclusion will be true too. The deductive reasoning goes from the general to the specific things. On the other hand, an inductive argument is an argument that may contain true premises and still has a false conclusion. Induction or the inductive reasoning is the form of reasoning in which we make a conclusion about future experience or about presence based on the past experience. The problem of induction also has a connection with the expressions as “a priori” and “a posteriori”. The truth in a priori statement is embedded in the statement itself, and the truth is considered to be as common knowledge or justification without the need to experience. Whereas, in order to determine if a pos...
on the ability of the thinker to be able to successfully think logically. According to the Oxford English Dictionary, logic is defined as "the science of reasoning, proof, thinking, or inference." Therefore, being able to think logically would assist in one's critical thinking abilities. Logic is not tainted by human emotion, and is therefore can be considered a reliable tool to accompany the critical thinking process.
Deduction is the third characteristic of rationalism, which is to prove something with certainty rather than reason. For example, Descartes attempted to prove the existence of God through deductive reasoning in his third meditation. It went something like this: “I have an idea of a perfect substance, but I am not a perfect substance, so there is no way I could not be the cause of this idea, so there must be some formal reality which is a perfect substance- like God. Because only perfection can create perfection, and though it can also create imperfection- nothing that is imperfect can create something that is perfect.
The logic used to explain miracles of everyday life, thinking logically helps man to question the functioning of everything around us, the logic used to argue and is somehow a thought an idea that influences us for an action we do in our daily lives.
The word logic indicates analysis. Analysis may be approved result or mathematical proof. Basic logical connectives are AND, OR and NOT. The collections of elements are called as set. Basic operations of sets are union, intersection and complement. Let us see solving logic and set theory in this article.
Euclidian logic begins with the inductive definition of very simple concepts and gradually constructs a vast body of results, organised in such a way so that each concept depends on the previous. Thus, a strong and rigorous construction is derived that makes all operations perceptible, comprehensible and intelligible. But, unlike processes that are physically constructed, Euclidian reasoning does not materially crumble if its structural elements, that is, its demonstrations, are not coherent with the reality of the empirical world. This explains why deductive-inductive logic, subtended by the philosophical-scientific thought of classical culture, has unconditionally influenced almost all fields of knowledge for almost two thousand years.
Inductive reasoning can be quickly summarized as a method through which a conclusion is drawn from particular cases; this conclusion may be applied to another specific case or generalized. All of our conclusions about the world around us, which we rely on daily without question, are dependent on this process. The expectation that our house will not cave in, that water will come from the faucet when turned on, that we will wake the next morning, are all propositions extrapolated from inductive arguments.
The reason I feel the concepts relates to interpretation and inference is that a lot of theories and law go through a process where the end result makes a conclusion or has makes a statement. Concepts consist of theories, definitions, axioms, laws, principles, and models. These are all used in the thinking process to make things have a meaning. As we go about these steps we can come to a set conclusions or interpretation of our theories. The last category is information and implications and consequences. According to criticalthinking.org (2007), information includes the facts, data, evidence, or experiences we use to figure things out. It does not necessarily imply accuracy or correctness. With this being said information can relate to implications and consequences because, they are claims or truths. Claims or truths have to be proven to be validated as a solution. This means information has to be collected to provide data, facts, observations, and experiences. This can relate to many thins one for example would be a pharmaceutical company trying to introduce a new drug and they say it will be better than any other similar drug on the
Inductive reasoning is logical reasoning where people have a lot of the information and use that to reach a conclusion. It is viewing the available data and figuring out what will be the results. For instance, from an online article, it demonstrates, “Inductive reasoning is a logical process in which multiple premises, all believed true or found true most of the time, are combined to obtain a specific conclusion” (Rouse, 2013). It shows that there are a lot of ideas to analyze and calculate what the possible outcomes will be. It can also be done by looking at patterns. When looking at patterns, it is important to study it to see what is recurring. This makes it possible to predict what will happen based on the knowledge that has been collected. Inductive reasoning is using information or events that have happened in the past to see what is in store for the future.
We can know some propositions in a particular subject area by intuition alone, or by deducting them from intuited propositions.
Mathematical logic is something that has been around for a very long time. Centuries Ago Greek and other logicians tried to make sense out of mathematical proofs. As time went on other people tried to do the same thing but using only symbols and variables. But I will get into detail about that a little later. There is also something called set theory, which is related with this. In mathematical logic a lot of terms are used such as axiom and proofs. A lot of things in math can be proven, but there are still some things that will probably always remain theories or ideas.
