Knowledge

Knowledge

The knowledge is a set of information stored by experience or learning ( a posteriori ), or through introspection ( a priori ). In the broadest sense of the term, it is about the possession of multiple interrelated data that, when taken by themselves, have a lower qualitative value.

For the Greek philosopher Plato , knowledge is necessarily true ( episteme ). Instead, belief and opinion ignore the reality of things, so they are part of the scope of the probable and the apparent.

Knowledge has its origin in sensory perception , then comes to understanding and finally ends in reason . It is said that knowledge is a relation between a subject and an object . The process of knowledge involves four elements: subject , object , operation and internal representation (the cognitive process).

The science believes that to achieve knowledge, it is necessary to follow a method. The scientific knowledge should not only be valid and consistent from the logical point of view, but also should be tested by the method scientific or experimental .

The systematic way of generating knowledge has two stages: basic research , where the theory advances; and applied research , where the information is applied.

When knowledge can be transmitted from one subject to another through formal communication, explicit knowledge is discussed . On the other hand, if knowledge is difficult to communicate and relates to personal experiences or mental models, it is implicit knowledge .
