The reasoning deductive, also known as deductive method comprises analyzing elements which allow reaching a positive or negative result. To put it better, a deduction is basically a type of argument in which the conclusion reached refers to the previous premises discussed.
Within logic as a discipline , there are several types of methods that make the construction of knowledge scientific: deductive, abductive and inductive reasoning . Among them, they differ mainly by the type of relationship they establish between the premises. Thus, in the case of deductive reasoning , it starts from a premise in general and its conclusion comprises a more particular aspect. For example:
1) All rice packets have a weight of 500 grams.
2) This is a packet of rice.
3) The weight of this package is 500 grams.
It is noteworthy that for this type of reasoning to be considered valid, there must be a coherent relationship between the first premise and the final conclusion of the logical sequence. Deductive Reasoning
This, which may seem to be just a question used in the field of science, to demonstrate a hypothesis or certain assumptions before an investigation, is something that in practice, in fact, has been used for a long time, having its origins in the society of Ancient Greece. For example, the renowned philosopher Aristotle was one of those who used this type of reasoning .
On the other hand, deduction, in addition to the scientific area, is achieved in a daily way in our lives. Deducing is part of our way of interpreting and understanding situations in the reality that surrounds us. For example, let’s look at a simple, everyday situation: 1) When a person doesn’t say hello to another, it’s because he doesn’t like or doesn’t like him. 2) When your mother-in-law meets you on the street and doesn’t greet you. 3) It follows that your mother-in-law doesn’t like you.
