Parsimóniu

Parsimóniu is a principle used in philosophy and science that suggests, when faced with competing hypotheses or explanations, one should choose the one that makes the fewest assumptions. This is often summarized as "the simplest explanation is usually the best." The term originates from the Latin word "parsimonia," meaning thrift or stinginess.

The principle is not a proof that the simpler explanation is always correct, but rather a methodological guideline or heuristic. It encourages scientists and philosophers to avoid unnecessarily complex theories and to favor explanations that are more elegant and easier to test. For example, if two theories can explain the same phenomenon equally well, the one with fewer hypothetical entities or processes would be preferred according to parsimóniu.

While widely used, the concept of simplicity can be subjective. What appears simple to one person might seem complex to another, and different types of simplicity exist. However, parsimóniu remains a valuable tool for guiding inquiry and for selecting among competing ideas in various fields of study. It promotes clarity, testability, and a focus on essential elements.
