Postulate is that expression that presents a true without demonstrations or evidence, but that is admitted despite the lack of evidence. The acceptance of the postulate is given by the absence of other expressions to which it can refer and by the need to use it in a subsequent reasoning.
The postulates, therefore, are propositions that allow to develop logical judgments. For the philosophy , are expressions that cannot be demonstrated from the theory , but they must be admitted to understand something. In this sense, the notion of freedom It can be understood as a philosophical postulate.
Another use of the postulate concept is associated with beginning that defend and promote certain groups or individuals. For example: "The sayings of the deputy are contrary to the historical postulates of socialism", "As a coach, my main postulate is respect for the rival", “I work for this company because I have no other option, but I don't agree with its postulates: I think they convey a message that is not healthy for society”.
In general, it can be said that the science He speaks of postulates to refer to those expressions that compile the experience regarding an idea. They are propositions that allow to base what is seen and that, so far, have not been proven false. Therefore, scientific propositions can be the starting point of a reasoning.
The geometry , on the other hand, accepts the propositions as assumptions that are taken to prove something, while the math more broadly, he understands the postulates as theoretical formulas accepted by convention.
