Despite some important observations and after decades of widespread consensus around the big bang cosmology, Fred Hoyle, one of the proponents of the steady-state cosmology, continued to fight the big bang idea throughout his life. We can try to understand this persistent attitude of Hoyle through a Holtonian thematic approach, by admitting that personal preferences and choices of scientists are conditioned by themata. Thematic analysis shows that big bang cosmology is mainly based on a set of themata consisting of evolution, (...) finitude, life cycle (which has a beginning), and change; the steady-state cosmology is based on opposite themata: steady-state, infinity, continuous existence, and constancy. Personal preferences seem to have been important in the strong and passionate dispute between big bang and steady-state ideas, and Hoyle is a very illustrative example of a personal commitment remarkably long-lived to some themata, in this case to the opposite themata of the big bang cosmology. In his personal and persistent struggle against the big bang idea, Hoyle always refused the way how some experimental observations were considered decisive in favor of this cosmology. This is a typical thematic attitude: letting some personal thematic preferences influence the acceptance or rejection of scientific evidence. In this case, that corresponds to the existence of selection effects and biases regarding important cosmological observations, in order to sustain a persistent rejection of the big bang idea.

The big bang idea is not only a dominant idea in cosmology but also a very successfully idea out of cosmology. Although sometimes just in metaphorical sense, the big bang idea is present, since some decades, in a variety of domains such as natural sciences, humanities, social sciences, arts, and it also has a great acceptance by the general public. Furthermore, the term Big Bang has become increasingly popular and currently it is often used with very different purposes, including commercial (...) purposes, in contexts that have nothing to do with science, such as music, television, cinema, circus, house decoration, food, and other unexpected domains. Proposed by Gerald Holton, thematic analysis is a useful tool for studying cases like this, because it identifies and describes elements that cross and connect all areas of knowledge and culture in general and thus can help to understand the reception, appropriation and use of certain ideas in different but contemporary disciplinary and cultural contexts, which may be involved in intellectual fashions and in styles of thought of one particular time.

This article focuses on the Omega Point, an essential concept in Teilhard de Chardin’s evolutionary metaphysics. In certain passages about the Omega Point, Teilhard mentions the primeval atom hypothesis, a theory about the beginning of the universe proposed by Georges Lemaître, another contemporary Jesuit priest who was also a scientist. Although Teilhard and Lemaître are essentially evolutionists, besides being Jesuit priests, their evolutionary metaphysics and their philosophies of science are radically divergent, and two important differences are presented here – about (...) the eventual cosmic determinism and about the relationship between scientific knowledge and religious beliefs. This article also shows how Teilhard’s original concept was projected into two cosmological theories in which it reveals an essential transfiguration by losing its initial anthropic and religious matrix – the cosmological anthropic principle, proposed by physicists John Barrow and Frank Tipler, and the Omega Point Theory proposed later by Frank Tipler.

Este artigo apresenta uma análise comparativa de dois conceitos propostos e desenvolvidos em duas áreas muito distintas: o conceito de themata, proposto por Gerald Holton na área de história da ciência para dar conta dos processos de produção e difusão do conhecimento científico, e o conceito de Pathosformeln, proposto por Aby Warburg na área de história da arte para dar conta de importantes continuidades históricas e epocais da produção artística. Apesar dos contextos disciplinares tão distintos em que foram propostos, e (...) apesar das especificidades que naturalmente asseguram a identidade própria de cada um dos conceitos, mostra-se neste artigo como themata e Pathosformeln têm inegáveis e importantes afinidades. De facto, ambos correspondem a entidades dotadas de longa persistência histórica, natureza cíclica e grande transversalidade disciplinar, cultural e epocal, em conjugação com uma grande capacidade de assumir formas específicas numa determinada época e num determinado contexto. Apesar de terem raízes em áreas muito distintas, as afinidades são suficientemente fortes para reconhecer aos themata e às Pathosformeln a pertença a uma mesma rede conceptual com grande potencialidade para a compreensão, não apenas da ciência e da arte, mas também das dinâmicas históricas e transdisciplinares da cultura em geral.

Some important and decisive observations allowed a widespread and almost unquestionable acceptance of the big bang cosmology, but we can admit and search other factors that have contributed and continue to contribute to the enormous acceptance and great popularity of this cosmological conception, not only inside but also outside of cosmology and even in numerous no scientific contexts. To find some of those factors, a case study was undertaken based on thematic analysis, an analytical tool which is based on the (...) idea that the scientific activity, in addition to a theoretical and an experimental dimensions, has a third dimension with psychological and cultural elements called themata that strongly influence the construction of scientific theories and also their acceptance or rejection. This case study focused on the most important founding texts of big bang cosmology, namely articles and books of Alexandre Friedmann, Georges Lemaître, and George Gamow, covering three decades of important developments, and the founding texts of its great rival, the steady-state cosmology. This article presents a summary of the main results of this case study, which allowed to identify several themata with a very important role in the big bang cosmology: differentiation and unification ; unity, creation, change, evolution, constancy, simplicity, life cycle, circularity, and disorder. All these themata form a methodological and conceptual matrix—with a triple dimension: historical, transversal/cultural, and psychological—that can help explain the acceptance and popularity of the big bang cosmology within and beyond its disciplinary boundaries.
