René Guénon in the context of "Aleksandr Dugin"

Traditionalism, also known as the Traditionalist School, is a school of thought within perennial philosophy. Originating in the thought of René Guénon in the 20th century, it proposes that a single primordial, metaphysical truth forms the source for, and is shared by, all the major world religions. Unlike universalist forms of perennialism based on commonalities in religious experiences across cultures, Traditionalism posits a metaphysical unitary source known as Tradition which forms the basis for the major religions in their "orthodox" forms.

Tradition has exoteric and esoteric dimensions. The exoteric aspects of a tradition are primarily represented by its ceremonies, rituals, and rules, whereas the esoteric aspects are concerned with its spiritual and intellectual qualities. Traditionalists often confront "tradition" to "modernity". While "tradition" has a transcendent origin, "modernity" takes little or no account of this dimension. Traditionalists defend the transcendent dimension of reality that they see as inherent in traditional religious expressions and worldviews. In contrast, they view liberal and modernist expressions of these traditions with suspicion, seeing their foundations as rationalistic, materialistic and individualistic.

Frithjof Schuon (/ˈʃuːɒn/ SHOO-on; German: [ˈfʁɪtjɔf ˈʃuːɔn]; 18 June 1907 – 5 May 1998) was a Swiss philosopher and spiritual leader, belonging to the Traditionalist School of Perennialism. He was the author of more than twenty works in French on metaphysics, spirituality, religion, anthropology and art. He was also a painter and a poet.

With René Guénon and Ananda Coomaraswamy, Schuon was one of the major 20th-century representatives of the philosophia perennis. Like them, he affirmed the reality of an absolute Principle – God – from which the universe emanates, and maintained that all divine revelations, despite their differences, possess a common essence: one and the same Truth. He also shared with them the certitude that man is potentially capable of supra-rational knowledge, and undertook a sustained critique of the modern mentality severed, according to him, from its traditional roots. Following Plato, Plotinus, Adi Shankara, Meister Eckhart, Ibn Arabī and other metaphysicians, Schuon sought to affirm the metaphysical unity between the Principle and its manifestation.
