The basic principles of the Infinitesimal calculus present the idea of ​​the true Infinity and its essential role in traditional teachings through the traditional understanding of the science of mathematics. Mathematics, as a sub-science, serves here as a symbolic illustration of metaphysical reality, as in all cases with former traditional sciences. Criticism of modern people's false concept of infinity and the traditional understanding of true Infinity is of primary importance in the spiritual-metaphysical realization. In this work, the Author illuminates through the presentation and correction of the infinitesimal calculus, i.e. the calculation of the indeterminably or "infinitely" small, that the spiritual and metaphysical end goal cannot be achieved simply by progressing step by step, but through a level breakthrough.

René GUÉNON (1886-1951) is the most outstanding and decisive figure in the restoration of the spiritual and metaphysical Tradition in its universality, as well as in the foundation of the traditional way of life. His 28-volume oeuvre is a solid foundation for rediscovering the basic principles of the traditional world, which is perhaps the last chance to eliminate modernity as a lost way, which threatens a catastrophic outcome. Knowing the traditional teachings in depth, from the central esotericism of the Primordial Tradition to the various partial - religious and other - applications, Guénon reveals the eternal wisdom inherent in them as a real guide, and at the same time allows an insight into the deepest levels of spiritual and religious practice, commensurate with the possibilities of written teaching.
