Who gave the First authoritative exposition of the Extremist ideological position within the Indian National Congress?

The beginning of extremism has its roots in 1905, but the rift started only after 1905 partition of Bengal. However, the first authoritative exposition of the Extremist Ideology was written by Arubindo Ghose or Sri Arubindo when he started writing series of articles under the title “”New lamps for old”” in late 1890s in a newspaper of Bombay, while he was engaged with Maharaja of Baroda. In this series, Sri Arubindo expressed the ideas that the Congress is wasting Indian time and energy by seeking trivial reforms.”
