John Locke is the author of a style called empiricism. According to his theory known as Tabula Rasa, human beings do not have knowledge. This is only linked to people's experiences, through learning. By making mistakes, winning, losing and getting things right, human beings develop.
Empiricism is nothing more than a theory that has to be proven through observation of actions or activities related to it. In other words, real experience is necessary to confirm the fact.
Empiricism teaches man to observe the world in a different way, without dissimulating reality. This increases knowledge, according to the theory.
Theory of Empiricism
The theory of empiricism comes from the works of René Descartes. John Locke had the job of gathering information about different experiences to prove the truth of some concepts. Therefore, human beings must use all their senses when observing a fact or object of study, and through these senses seek the closest definition to reality.
Thus, knowledge, or metaphysical data, were not accepted in empiricism. David Hume was another important empirical author, who tried to prove that causality is not true. What exists, for him, is a series of chronological events that seem to refer to something casual.
Other empirical authors are Aristotle, Thomas Aquinas and Francis Bacon.
Empiricism greatly served the practice of science and changed the system of scientific methodology.
