The deductive method or deduction It is one of the most used methods to achieve, obtain, conclusions on various issues. The distinctive feature of this scientific method is that the conclusions have always been printed on the premises, that is, it is possible to infer the conclusion of the propositions that make up an argument, from them and only from them it becomes.
This method is not something that modernity brought with it, far from it, but it is a method that was already referenced in classical antiquity by philosophers of the stature of Aristotle.
On the other hand, the deduction, always starts from a question or general law to get to the particular, that is, goes from the general to the particular and this is what confronts him with inductive method that moves on the opposite side: from the particular to the general.
All Spaniards are happy, Miguel is Spanish, so Miguel is happy. The exposed is an authentic postulate of the method that occupies us, however, it is important that we point out that when the propositions are true the deductive reasoning will be valid and therefore there will be no way that the conclusion is not also true.
Meanwhile, those who criticize this method, such is the case of the philosopher Francis Bacon, staunch defender of the inductive method, consider that this going from the general to the particular is what can inevitably lead to an erroneous conclusion, precisely because of the generalization in which it is incurred, it will be different when starting from particular questions and then arriving to a general conclusion.
Another differential feature of this method is the use it makes of different tools and elements to demonstrate or clarify issues. Schemes, graphical tables, synopses, among others, that collect the various propositions as well as the relationships that are established between them and that are the ideal assistants in this regard.
