Raymond Aron was a student of Léon Brunschvicg, a representative of French historical epistemology. This article explores Aron’s relation to this tradition through three claims. First of all, it contests that Raymond Aron’s philosophy of history constituted a complete break with this tradition. Secondly, resituating Aron in this tradition is valuable, because it highlights how Aron’s own philosophy of history is to be understood as a normative project, seen as an alternative to that of Brunschvicg. Finally, Aron’s philosophy can still hold valuable lessons for present-day historical epistemology and history and philosophy of science in general.

Many young dreamers who want to be modern up to the tips of their toes, and who think they have gotten rid of these barely imaginable old-fashioned ideas, are, without realizing it, mystics in search of a spiritual experience. (Gauchet 2003 , p. 311) Several sociologists of science have mobilized secularization metaphors to describe developments in the study of science. Similar to how secularization refers to a decreasing status of religion and God as a transcendent factor in society, the secularization of science refers to an abandonment of Science as something “sacred” and Nature as transcendent. This article aims to explore these secularization metaphors, by arguing for a parallel between how sociologists and philosophers of religion differ and how similar disagreements between sociologists of science and the work of Bruno Latour exist, whose work should rather be linked with that of other philosophers, such as Michel Serres and Isabelle Stengers.
