The etymology from empirical refers to Latin empiric, which in turn derives from the Greek Empeirikós. The notion refers to what relates to the experience .
It is understood by experience , meanwhile, to the fact know or know something about situations already lived . The experience is acquired with the practice and the experimentation .
The empirical, in short, is based on experience. This type of knowledge arises from the sensory perception that allows to register the reality.
It is known as empiricism to philosophy focused on the role of experience when learning. For empiricism, experience is the starting point for generating knowledge. The empirical, in this framework, is used for the development of concepts (which are justified as perceived with the senses).
The idea of empirical logic , on the other hand, refers to the sustenance of the call empirical method . According to this logic , the observation of the links between what is perceived and its relative variations constitutes the basis for the establishment of the laws of knowledge.
In this way, the empirical method uses empirical logic and experimentation for the production of knowledge. Its objective is to discover the most important features and key relationships of the object of study, accessing them through the senses .
The empirical method is factual (concentrates on events), demonstrates its hypothesis contrasting them with perception and accepts the progressive construction of knowledge. This means that, with the empirical method, conclusions that are considered infallible and immutable are not postulated.
