Foundation Of Mathematics
Foundations of mathematics are the logical and mathematical framework that allows the development of mathematics without generating self-contradictory theories, and to have reliable concepts of theorems, proofs, algorithms, etc. in particular. This may also include the philosophical study of the relation of this framework with reality. The term "foundations of mathematics" was not coined before the end of the 19th century, although foundations were first established by the ancient Greek philosophers under the name of Aristotle's logic and systematically applied in Euclid's ''Elements''. A mathematical assertion is considered as truth only if it is a theorem that is proved from true premises by means of a sequence of syllogisms ( inference rules), the premises being either already proved theorems or self-evident assertions called axioms or postulates. These foundations were tacitly assumed to be definitive until the introduction of infinitesimal calculus by Isaac New ...

Pragmatism
Pragmatism is a philosophical tradition that views language and thought as tools for prediction, problem solving, and action, rather than describing, representing, or mirroring reality. Pragmatists contend that most philosophical topics—such as the nature of knowledge, language, concepts, meaning, belief, and science—are best viewed in terms of their practical uses and successes. Pragmatism began in the United States in the 1870s. Its origins are often attributed to philosophers Charles Sanders Peirce, William James and John Dewey. In 1878, Peirce described it in his pragmatic maxim: "Consider the practical effects of the objects of your conception. Then, your conception of those effects is the whole of your conception of the object."Peirce, C.S. (1878), " How to Make Our Ideas Clear", ''Popular Science Monthly'', v. 12, 286–302. Reprinted often, including ''Collected Papers'' v. 5, paragraphs 388–410 and ''Essential Peirce'' v. 1, 124–141. See end of §II for ...

Noosphere
The noosphere (alternate spelling noösphere) is a philosophical concept developed and popularized by the biogeochemist Vladimir Vernadsky and philosopher and Jesuit priest Pierre Teilhard de Chardin. Vernadsky defined the noosphere as the new state of the biosphere, and described it as the planetary "sphere of reason". The noosphere represents the highest stage of biospheric development, that of humankind's rational activities. The word is derived from the Greek νόος ("nous, mind, reason") and σφαῖρα ("sphere"), in lexical analogy to "atmosphere" and "biosphere". The concept cannot be accredited to a single author. The founding authors Vernadsky and de Chardin developed two related but starkly different concepts, the former grounded in the geological sciences, and the latter in theology. Both conceptions of the noosphere share the common thesis that together human reason and scientific thought have created, and will continue to create, the next evolutionary geologi ...

The Holy Office justified that decision by referring to chapter 13 of Paul the Apostle's Epistle to the Romans regarding state authority coming from God. However, somewhat later, the Vatican criticized in the encyclical (March 1937) about the challenges of the church in Nazi Germany. Abolition (1966) On 7 December 1965, Pope Paul VI issued the that reorganized the Holy Office as the ''Sacred Congregation for the Doctrine of the Faith''. The Index was not listed as being a part of the newly constituted congregation's competence, leading to questioning whether it still was. This question was put to Cardinal Alfredo Ottaviani, pro-prefect of the congregation, who responded in the negative. The Cardinal ...
