In this article I try to bring to light the convergences and divergences between the German reformer Marthin Luther and the Danish philosopher Kierkegaard. For this purpose, the text was subdivided into four chapters so that it could be possible to bring the main ideas of the authors. The dialogue between Luther and Kierkegaard, where the author defends freedom of conscience as being a freedom from, as Luther does, since our freedom is only found when we love Christ, with a (...) passion so distinct that we are willing to risk everything for him and at the same time sacrifice everything for him. According to Kierkegaard the subject who is able to be alone in the world, consulting only his conscience is a hero. Kierkegaard appeals to Luther, the solitary monk who faced the Emperor and the Pope, leading first to the creation and strengthening of consciousness in silence and solitude. Thus, only the lonely subject before God, willing to make all sacrifices for God can be free, while the second Luther led to a vision that leads subjects to the abolition of conscience, seeking the forgiveness of sins in Christ so that it is possible to have fun in life. The love of God, which for Luther leads us to freedom for Kierkegaard, keeps us imprisoned and anguished, because the subject will be aware that he will never be able to reciprocate such love. In order to be able to appease such anxiety, you must have a life totally surrendered to Him. (shrink)

Historically, taxonomy, which is the area responsible for describing new species, used a priori only morphological characteristics. Darwin already pointed out that there was a great divergence among taxonomists when they classified some organism as a species. When a new species is described, due to its historical weight, the morphological characters are considered as the first species demarcation criterion, however, with the advance of genetics and molecular biology, new methods are added. The use of multiple methods seems to be necessary (...) for us to develop a contemporary taxonomy, so, a little more than a decade ago, the “integrative taxonomy” emerged, which refers to a taxonomy that aims to integrate all available data sources to frame the data. species limits. Data integration is not possible, as we do not have the technological capacity to do so. In view of this, we can interact the data through interactive taxonomy, which suggests, a way of treating the data under the assumption of different lines of evidence, through which the explanations have logical consequences that can be tested, mitigating the subjectivity of the subject in the process. Data interactions can overlap taxonomic descriptions, as they could encompass different phenomena and problem solving, thereby mitigating subjectivism. Therefore, in different fields, at least two indications would be necessary, which could be contained in two different approaches, one hypothetical and one by estimation. Such interpellations would contain evidence with different assumptions and dissimilar data characteristics, thus increasing the number of evidence, as well as improving the reliability of the argument. In this way, we can bring new species to light with a more objective bias and with less likelihood of error. Keywords: Taxonomy. Cryptic species. Estimation. Hypothetical. (shrink)
