SBE 48: The Vedanta-Sutras with commentary by Ramanuja, George Thibaut, tr.: First Pâda: 11. Also in consequence of the ill-foundedness of reasoning

11. Also in consequence of the ill-foundedness of reasoning. The theory, resting on Scripture, of Brahman being the universal cause must be accepted, and the theory of the Pradhâna must be abandoned, because all (mere) reasoning is ill-founded. This latter point is proved by the fact that the arguments set forth by Buddha, Kanâda, Akshapâda, Gina, Kapila and Patañgali respectively are all mutually contradictory.
