Expanded ScienceJoao Carlos Holland de Barcellos,translated by Debora PolicastroIf truth were not the objective of philosophy, the Grimm brothers would have been the biggest philosophers in the world (Jocax)Abstract: initially, in this article, we present the foundation on which current science stands. Next, we explain the main stream of modern science, the Popperian Falsificationism, and show why the current criticism to the system is flawed. Later, we will prove that the falsificationism is logically inconsistent and we will propose a new concept of science, unifying it with philosophy.1-The objective of ScienceScience has truth as its only objective. This objective is essential to any tentative of classification in science.2-Basic Postulates of Science.2.1- Compatibility with the FactsThe Truth in science can be defined as all information compatible with reality. The term compatible with reality, in our definition of truth, must be understood as according to the facts, never in contradiction to them. This way, compatibility with the facts provides the empirical feature of science, as it links the scientific truth to the reality of the facts.2.2 The Universe is LogicalLikewise, we must also take the fact that our universe is logical as a scientific postulate. That is, the universe defined as the set of all that exists does not present logical contradictions between its element and laws. It must, therefore, follow the classical logic (aristotelic). Such an assumption is important because no illogical events have ever been verified in the universe. Secondly, if contradiction was allowed, science would be trivialized, that is, every kind of affirmation would be true, even if it was absurd, since a logical system with incompatible premises necessarily implies that any proposition is true. In the appendix A, at the end of this text, we prove that the proposition the universe does not exist can be logically derived from a logical system that presents contradictory premises. Some usual definitions of science can be found in the appendix B. 1. The scientific methodThe set of rules with which science seeks knowledge (information considered true or highly reliable) is what we usually call Scientific Method.3.1-"The Deductive Method"The deductive method comes from the assumption that the universe is logical, so the logical inferences can be applied to scientific theories in order to extract other theories which, by logical consequence, should also have the same degree of reliability. The basis of the deductive method is the logical syllogism known as "modus ponens" [8]: H => D (If "H" implies "D") H (and "H" happens, i.e. H is true)=> D (We can conclude that "D" will also happen)This rule can be summarized in the following tautological formula:((H => D) ^ H) => D(If "H" implies "D" and "H" happens, we can conclude "D").Example: "If all geese are white" and my aunt has a goose, I can conclude that it is white. Thus, from the general theory H: "all geese are white", we can extract the particular theory D, "my aunts goose is white."3.2-"The Hypothetical Deductive Method"One of the most important rules of the scientific method, "The Hypothetical-Deductive Method" is based on the logical tautology known
