Positivism should be referred to as a persistent philosophical current that focuses on empirical data as a source of valuable scientific information.
In other words, positivism defines the possibility of knowing reality through the practical experience of the individual sciences; each of the scientific disciplines is allowed to contribute to a unified knowledge. Philosophy serves as an integrating force to bring this isolated knowledge together.
From a research perspective, positivists do not seek to explain the phenomena or discoveries they discover but to capture them. Placing positivism in an early psychological discipline allows us to trace the ideas of the evolution of the human person through cognition: this is how the individual discovers reality for himself by studying the world.
Positivism called for a rejection of metaphysical terminology, which helped create a scientific, credible basis for psychological research. In this sense, observation was used as a practical approach to study, and it was an observation that became the basis for modern psychology.
