Cosmologia e Representac{c}~ao

This work presents a brief and non-technical description of the main results and concepts of the modern scientific cosmology, viewing it from an epistemological perspective which allows a dialog with other modes of thinking like e.g. history, philosophy, sociology and religion. This epistemological viewpoint is based on the philosophical theses advanced by Ludwig Boltzmann (1844-1906) which states that scientific theories are nothing more than representations, or images, of nature (arXiv:physics/0701308v1). By being representations one cannot know how nature really is because the intrinsic and indispensable properties that characterize nature are unreachable by science. In other words, the true essences that constitute nature are unknowable. Therefore, all answers proposed by science are partial, simplified and replaceable. Another way of putting forward this viewpoint is to state that all scientific truths are provisional, a result which naturally leads to the conclusion that the same set of phenomena, or scientific questions, may have various answers, or representations. This conclusion is generally known as theoretical pluralism (arXiv:physics/9806011). It is exactly such a plurality for conceiving, or representing, nature that opens the way for a possibly fruitful dialog among the various forms of thinking, since this dialog can take place in the realm of the representations. A few examples taken from cosmology, sociology and theology are discussed in the context of this epistemological framework.
