Aleksei Aleksandrovich Kozlov (Russian: Алексей Александрович Козлов; 20 February 1831 – 12 March 1901) was a Russian philosopher known for his contributions to Russian idealism. He is recognized as the founder of the "neo-Leibnizian" movement in Russia, which involved updating the ideas of philosopher Gottfried Wilhelm Leibniz, as well as the works of R.H. Lotze and Gustav Teichmüller. Kozlov's philosophy is also considered a precursor to Russian personalist metaphysics.[1]
Kozlov's influence on Russian philosophy extended beyond his own ideas. He played a crucial role in defending speculative philosophy against the dominant positivism of his time.[1] Kozlov's legacy is significant due to his contributions to the development of Russian philosophy at the end of the 19th century and the ongoing impact of his philosophical ideas in the 20th century.[1][2]
