Thomas Kuhn's philosophy brought a series of important ways of interpreting scientific practice, where history came to be understood as a significant part of this dynamic. In his 1962 “The Structure of Scientific Revolutions”, Kuhn provided us with some important concepts such as paradigm, normal science, anomalies and extraordinary science. From then on, science was no longer seen only as a logical structure related to discovery – but it was suggested that scientific changes occurred due to an increase in unresolved (...) problems that were sometimes ignored; contrary to what a science standardized by Popper's falsificationism could propose. Science in its normal period would be extremely traditionalist, remaining faithful to its paradigm and ignoring a series of problems – the paradigm being, among various ways of describing such a term, as a matrix of models. After many ignored and unresolved problems, a crisis can set in and from this process new paradigms can emerge: note that this dynamic can be related to a historical process within science. (shrink)

In 2003, the then president of the United States, George W. Bush, started a war against Iraq, under the arguments that Saddam Hussein had possession of several weapons of mass destruction and that he harbored members of Al-Qaeda. The question of the existence of these weapons was questionable, but it led to a war that culminated in Hussein's removal from power and his arrest – later sentenced to death for his conduct in that country. It is interesting to show that (...) the existence – or not – of that arsenal, never seen before, is a question about an ontology. The question about how the intelligence service arrived at this answer is epistemic; defining how a conclusion is reached, like the one we illustrate, or how it is sustained, are epistemological biases.

Firstly, it is with great satisfaction that we have started publishing the "Revista Epistemologia". One of the tasks we will pursue is to discuss the specialty of Epistemology itself as well as its interfaces, within or outside philosophy. To begin this edition, it is necessary for us to reflect on this important area of philosophy, and in turn a metaphilosophical reflection.

We open number 3, volume 3, in 2022 with some reflections about the time in which we are present: to contextualize we need to mention that our country is about to hold general elections, in a situation that has increasingly worsened in relation to the risk to the integrity of the election – where the president of the republic has attacked the reliability of electronic surveys in exchange for avoiding proof of his suspicions; in addition to raising a tangle of (...) argumentative confusion to deter various unfounded suspicions. We live in a period in which fake news, popularly called fake news, runs freely on instant messengers and, even before any verification of its veracity, is taken as real things and propagated in the name of ignorance, the permanence of power and hatred.

This paper describle about the discovery and development of the concept of the particle named "neutrino", using the perspective of the philosophy of science of Imre Lakatos. With this focus, we making a historiographical and epistemological analysis of scientific practice, which culminated in its formulation, as well as subsequent developments. In this sense, the work makes a rational reconstruction regarding the research program that the formulation and discovery of the neutrino participates in, as well as the principle of conservation of (...) energy that can be understood as a fundamental part of the methodological assumptions of such program.

This dissertation attempts to apply Imre Lakatos' Philosophy of Science to the research program of Mary Schweitzer and staff, presented in two papers published in Science: one of them about the discovery of T-Rex with soft tissue and a later one reporting the detection of collagen. This case-study highlights the more general applicability of Lakatos' Methodology of Scientific Research Programmes to scientific practice in Evolutionary Biology.
