Do you really know what a paradigm is?

The first version of this work, published in 2003, appeared in a modest article in some electronic magazine of the time, and twenty years have passed since then, and today we are in the middle of 2022. The author could never have imagined that endless amount of messages, sent by people interested in such a specialized subject, within the complexity of a critical study, focused on the polysemy that hides the simple word Paradigm. This term can be found today in hundreds of scientific texts, in articles of the most varied contexts and even in a simple daily conversation. In general, its current use comes from the sense that has been generalized from Kuhn's work, "The structure of scientific revolutions", and it is in this perspective that we present today a new version of Do you really know what a paradigm is? In this perspective, we present today a new version of Do you really know what a paradigm is, which broadens but does not change the purpose of highlighting the polysemic problems that are increasingly present in some contemporary sciences.
