“The Magus of the North” (1993) is the last lifetime book of the British thinker Isaiah Berlin (1909–1997), which is part of his series of studies dedicated to the central figures of the counter-Enlightenment: Joseph de Maistre, Giambattista Vico and Johann Gottfried Herder. The hero of Berlin's book, Johann Georg Hamann (1730–1788, a half-forgotten contemporary of Kant, who, like him, lived in Königsberg, appears in his essay not so much as a reactionary and detractor of the idea of autonomous reason, but as an original thinker who became the forerunner of the main trends in the philosophy of our time - ideas of the linguistic nature of thinking, the inseparability and interpenetration of nature and culture, the affective foundations of cognition and the plurality of types of rationality.
