This cult was a later reinterpretation of the worshiping of Logic, Reason and Knowledge: they were supposedly the teachings of a prophet -called Zsience- who was credited with having revealed the Tekkno-Loki using what was called 'Zsientific Knowledge'.
The Cult of Zsience, to interpret the revealed truths and re-discover Tekkno-loki used a dogmatic study of their faith they called the 'Zsientific Method', which was a body of techniques for investigating the divine Tekkno-loki phenomena, acquiring new zsientific knowldge or correcting and integrating previous revealed knowledge by Prophet Zsience.
This method consisted in the systematic observation, measurement and experimentation, and the formulation, testing and modification of the so called 'Hyp Otheses', revealed truths by Zsience to his priests.
For long, the Cult of Zsience would be the most common religion practiced in the Dumian Empire, but other religions were still allowed, as long they didn't contradict the Zsientific dogma of the state.
In the first age of Dume, during the rule of the Librarians, the city of Dume was proudly defined by the Librarians as an agnostic -sometimes atheist- society, where there was no gods or religion, as Dume was ruled by reason and Tekkno-loki knowledge. However, their initial, ferocious anti-religious stand will come to produce internal clashes and conflicts, which will force the last librarians -and the early Dumian Republic- to introduce laws that guaranteed the free exercise of religion, but as well forbade the Librarians or later Republican government from passing laws respecting its establishment -a prohibition that was made to ensure the continued religion-less characteristic of Dume-.
However with time, the ideal of the ancients -agnosticism- and their reverence to reason and Tekkno-loki will come to be a state-promoted cult, the Cult of Zsience.
The Cult of Zsience will become inseparable of Dumian's official deities, whose cult was essential to Dume's survival and whose neglect was therefore treasonous. The traditional cult was a focus of Dumian Imperial revivalist legislation under some emperors.
Christian apologists and martyr-ologists saw the cult of Zsience as a particularly offensive instrument of "pagan" impiety and persecution. It therefore became a focus of theological and political debate during the ascendancy of Christianity during the Dumian Empire. The Zsientific emperors failed to reverse the declining support for Dume's official religious practices: later emperors adopted Christianity as Dume's state religion. Dumian's traditional gods and "Cult of Zsience" were officially abandoned. However, many of the rites, practices and status distinctions that characterized the cult were perpetuated in the philosophy, theology and politics of the Christianized Empire.
