Who authored 'In Defence of Liberalism'?

K.M. Panikkar

The correct answer is Option 1- K.M. Panikkar

Indian liberalism has two streams. The first stream began with Rammohan Roy. He emphasised individual rights, particularly the rights of women. The second stream included thinkers like K.C. Sen, Justice Ranade and Swami Vivekananda. They introduced the spirit of social justice within orthodox Hinduism. For Vivekananda, such a reordering of Hindu society could not have been possible without liberal principles.
