A syllogism is a form of reasoning; a logical argument derived briefly. This form of rational thinking was initially established by the Greeks, specifically Aristotle. It is a form of deductive reasoning that derives a conclusion based on two premises. The conclusion holds if the premises that it is set on are true. A simple example to understand the syllogism is - if all dogs are animals, and all animals have four legs, all dogs have four legs.
Syllogisms are an integral part of deductive reasoning, introduced to children in their primary school. It enhances the child’s logical reasoning ability and encourages them to conclude with the help of verbal reasoning. It is an effective way to allow children to engage with problems and come to logical solutions.
Several entrance exams at later stages also have questions based on syllogism to assess the deductive reasoning ability of the candidates. There are majorly three elements in a syllogism with a premise, a minor premise, and a conclusion. Let us look at the kinds of syllogisms to understand the concept better.
Types of Syllogisms
There are different types of syllogisms having varied elements.
1. Categorical Syllogism: The rule that categorical syllogism follows is “If A is a part of B and B is a part of C, then A is a part of C”.
Major premise: All roses are flowers.
Minor premise: I am holding a rose.
Conclusion: I am holding a flower.
2. Conditional Syllogism: The rule that conditional syllogism follows is “If A is true, B is also true”. These kinds of syllogisms are often known as hypothetical syllogisms since they aren’t logical. The conclusion holds only if the given premises are true.
Major premise: Riya is smart.
Minor premise: Riya will score well because she is smart.
Conclusion: If Riya is smart, she will get into a good university.
3. Disjunctive Syllogism: The rule that disjunctive syllogism follows is that “Either A or B is true, if A is false, then B will be true”.
Either statement: This cake is either pineapple or blueberry.
False premise: It is not blueberry.
Conclusion: Therefore, this cake is pineapple.
While these are the basic kinds of syllogisms, there are also some rules to be followed while creating syllogisms.
Rules in Syllogism
The rules for making syllogism questions are:
- The middle term must be distributed at least one time in the problem.
- If a term has been distributed in the concluding statement, it must be distributed in the premise as well.
- There cannot be two negative premises in a syllogism.
- A negative premise will have a negative conclusion, and a positive premise will have a positive conclusion.
- If both the premise statements are a universal truth, then the conclusion must be a universal truth as well.
Tips for Solving Syllogism Questions
The best way to solve syllogism questions and get the maximum correct answers is to use a Venn diagram. Here are some general tricks useful while answering such questions.
- Pay close attention to words such as “a few”, “at least”, “all”, and “not”. These are the basics for understanding and solving such questions.
- Always form a Venn diagram to double-check your verbal reasoning. It is the most effective way of solving syllogism questions quickly.
- Never make assumptions of your own while attempting these questions. The only truth applicable is what the premise and the question tell you. Thus, never create any logic of your own, as it will only complicate the problem for you.
By following these tricks, it will become relatively easy to get correct answers in less time. The more questions one practices, the quicker and more effortless the whole process becomes.
Benefits of Teaching Syllogisms to Students
There are several advantages of teaching children, especially young learners, the method of deductive reasoning. Some merits have been listed below:
- Time-saving method: Since all kinds of syllogisms have their own rule, it becomes time-saving to solve equations. Solving problems becomes simpler with the help of pre-established formulas.
- Pushes the memory: Children have to remember the previous equations and know the rules to derive a sense of any equation. Thus, teaching by syllogisms encourages children to boost their memory power.
- Encourages logical thinking: Syllogisms are based on logic more than anything else. Hence, they encourage logical thinking by young learners and adults. Even with the pre-established formulas, there is a need for applying logic to enhance understanding.
- Increased clarity: By deductive reasoning, children can gather where the conclusions have come from. They are not matter-of-fact things but logical reasoning to derive the conclusion themselves, which provides increased clarity.
- Conscious learning: Deductive reasoning taught via syllogisms help promote conscious learning. Adult learners can consciously learn what they are taught without the need for detailed explanations and passive acceptance.
- Enhances problem-solving ability: Syllogisms encourage the child to engage with the question till they reach a valuable conclusion, thereby encouraging problem-solving.
While these are some benefits of teaching syllogisms to students, we cannot forget how fascinating syllogisms are for young minds. Creating Venn diagrams to solve such questions can be fun-filled at the same time, encouraging their reasoning abilities.
Thus, once established by the Greeks to encourage logical reasoning, syllogisms have now become a crucial part of the curriculum. Not just in the school examinations, but syllogisms are present in entrance exams and government exams because of their applicability in judging a person’s reasoning and deductive abilities. For this reason, children are encouraged to understand and practice syllogism from a young age.
