The principle of the law of syllogism posits that it is feasible to eliminate intermediary stages within the framework of deductive reasoning. If a proposition A implies a proposition B, and proposition B implies a proposition C, it is plausible to assert that proposition A implies proposition C.
The rule of syllogism may be used to scenarios with two assertions including three occurrences, as well as to more complex scenarios involving strings of hundreds of statements. For the abridged statement to be true, it is necessary that all intermediate conditional assertions be true.
It is important to note that an antecedent refers to the component of a conditional statement that comes behind the term "if." The consequence refers to the subsequent portion that follows the term "that." In the context of a syllogism, the antecedent of one assertion serves as the consequence of another statement.
Given that the veracity of a preceding statement entails the veracity of a subsequent statement in a valid conditional proposition, it is logical to concatenate the assertions and exclude the intermediary portions.

Real-Life Examples Of The Law Of Syllogism
The Law of Syllogism is a fundamental principle in logic that helps us draw conclusions from conditional statements. This law is widely applicable in various real-life scenarios, allowing us to make logical deductions based on the given information. Here are some examples of how the Law of Syllogism is applied in everyday situations:
Example 1 - Employment Criteria
If a candidate has a master's degree, then they are eligible for a senior position. If a candidate is eligible for a senior position, then they will have a higher salary. Therefore, if a candidate has a master's degree, then they will have a higher salary.
Example 2 - Voting Eligibility
If a person is over 18 years old, they are eligible to vote. If a person is eligible to vote, they can participate in the election. Therefore, if a person is over 18 years old, they can participate in the election.
Example 3 - School Graduation
If a student completes all required coursework, they will graduate from school. If a student graduates from school, they will receive a diploma. Therefore, if a student completes all required coursework, they will receive a diploma.
Example 4 - Online Shopping Discounts
If a customer spends more than $100, they receive a 10% discount. If a customer receives a 10% discount, their final bill will be reduced. Therefore, if a customer spends more than $100, their final bill will be reduced.
Example 5 - Fitness Progress
If a person exercises regularly, they will become physically fit. If a person becomes physically fit, they will have more energy. Therefore, if a person exercises regularly, they will have more energy.
The Structure Of A Syllogism
In a syllogism, the primary premise is characterized by its broad and inclusive nature, exemplified by statements such as "All triangles possess three sides and three interior angles." The primary proposition is sometimes expressed as a conditional statement, beginning with the term "If."
The minor premise reduces the scope of the premise to a specific, precise, or familiar context, stating, "This geometric shape is a polygon with three sides." Additionally, it is possible to construct a conditional statement that starts with the word "If."
The conclusion establishes a link between the general fact presented in the major premise and the specific instance provided in the minor premise, resulting in the statement that "this three-sided polygon is a triangle." Conclusions often start with the transitional phrase "Then."
The principle of the rule of syllogism is sometimes referred to as reasoning via transitivity. The aforementioned concept has a resemblance to the transitive characteristic of equality, which posits that if one object, referred to as the "whatsit," exhibits similarity to another object, denoted as the "doohickey," and said doohickey bears resemblance to a third object, termed the "thingamabob," then it follows that the initial whatsit also shares similarity with the aforementioned thingamabob.
In the event that an is equal to b,
In the event when b is equal to c,
The equation "a = c" is true.
In order to illustrate the concept, the premises of the aforementioned example might be reformulated as conditional statements.
If it is true that every triangle has three sides and three interior angles,
Moreover, in the case of a three-sided polygon,
Therefore, it may be concluded that the polygon with three sides is classified as a triangle.
The rule of syllogism is a logical principle that involves two conditional assertions, each consisting of a "If" clause, followed by a conclusion denoted by "Then". In the field of logic, it is customary for logicians to allocate letters to various components of the syllogism.
- Statement 1: If proposition p is true, then proposition q is also true.
- Statement 2: If q is true, then r is true.
- Statement 3 posits that if p is true, then r must also be true.
The two aforementioned statements, referred to as premises, are the foundational components of the argument. If the premises are accurate, then it may be inferred that assertion 3 is a valid deduction.
Applications Of The Law Of Syllogism
