In order that men should embrace the truth — not in the vague way they did in childhood, nor in the one-sided and perverted way presented to them by their religious and scientific teachers, but embrace it as their highest law the complete liberation of this truth from all and every superstition (both pseudo-religious and pseudo-scientific) by which it is still obscured is essential: not a partial, timid attempt, reckoning with traditions sanctified by age and with the habits of the people — not such as was effected in the religious sphere by Guru Nanak, the founder of the sect of the Sikhs, and in the Christian world by Luther, and by similar reformers in other religions — but a fundamental cleansing of religious consciousness from all ancient religious and modern scientific superstitions.
Leo Tolstoy
