'Elementary my dear Watson!' Sherlock Holmes would proclaim after solving another mystery. Holmes would then proceed to explain how he had figured out through logic the way the crime had been committed. This process of working out what must be true from the facts of a case is deductive reasoning.
If you are given a set of facts about a case like Sherlock Holmes, deduction is the process where you examine the relationships of those facts and figure out what else must be true. Deduction occurs when we apply the law of non-contradiction to problems of categories, if/then claims, or the application of rules.
Well, now that we know you should not poke Socrates, and that bears are mortal, we now should discuss how you can use these skills in life and what methods you can use to solve deductive problems.
Deductive reasoning, also deductive logic, is the process of reasoning from one or more statements (premises) to reach a logical conclusion. Deductive reasoning goes in the same direction as that of the conditionals, ...
In other words, the conclusion must be true if the premises are true. An argument can be “valid” even if one or more of its premises are false. An argument is “ sound ” if it is valid and the premises are true. It is possible to have a deductive argument that is logically valid but is not sound.
In inductive reasoning, the conclusion is reached by generalizing or extrapolating from specific cases to general rules resulting in a conclusion that has epistemic uncertainty. The inductive reasoning is not the same as induction used in mathematical proofs – mathematical induction is actually a form of deductive reasoning.
Modus ponens (also known as "affirming the antecedent" or "the law of detachment") is the primary deductive rule of inference. It applies to arguments that have as first premise a conditional statement (. ) of the conditional statement. It obtains the consequent (. ) of the conditional statement as its conclusion.
Modus tollens (also known as "the law of contrapositive") is a deductive rule of inference. It validates an argument that has as premises a conditional statement (formula) and the negation of the consequent (. ).
The first premise states that all objects classified as "men" have the attribute "mortal.". The second premise states that "Socrates" is classified as a "man" – a member of the set "men.". The conclusion then states that "Socrates" must be "mortal" because he inherits this attribute from his classification as a "man.".
In term logic the law of syllogism takes two conditional statements and forms a conclusion by combining the hypothesis of one statement with the conclusion of another. Here is the general form:
Reasoning is a good way to convince someone to do something. There are two basic kinds of reasoning deductive and inductive. In this lesson we're going to look at deductive reasoning and how it can help you win an argument and be a better scientist. Updated: 11/09/2020. Create an account.
Naomi has a Science Olympiad meeting on either Wednesday or Fri day. She just found out that the meeting is not on Wednesday, so the meeting must be on Friday. If both things are true, there is no way that the meeting could be on another day. We are certain, so this is deductive reasoning.
Let's take this example: 1. All Mammals are warm-blooded. They drink their mother's milk, they have fur, and they have a backbone. 2. People are warm-blooded. They drink their mother's milk, they have fur, and they have a backbone.
All turtles are not people. Turtles are reptiles and they are not warm-blooded so they cannot be people. We have to make sure that the arguments we present are true in order to have a true and certain conclusion. Lesson Summary. Deductive reasoning means we can draw a conclusion based on at least two true premises, or statements.
