...Whilst on board the Beagle I was quite orthodox, and I remember being heartily laughed at by several of the officers... for quoting the Bible as an unanswerable authority on some point of morality... But I had gradually come by this time, i.e., 1836 to 1839, to see that the Old Testament from its manifestly false history of the world, with the Tower of Babel, the rainbow at sign, &c., &c., and from its attributing to God the feelings of a revengeful tyrant, was no more to be trusted than the sacred books of the Hindoos, or the beliefs of any barbarian....By further reflecting that the clearest evidence would be requisite to make any sane man believe in the miracles by which Christianity is supported, (and that the more we know of the fixed laws of nature the more incredible do miracles become), that the men at that time were ignorant and credulous to a degree almost uncomprehensible by us, that the Gospels cannot be proved to have been written simultaneously with the events, that they differ in many important details, far too important, as it seemed to me, to be admitted as the usual inaccuracies of eyewitnesses; by such reflections as these, which I give not as having the least novelty or value, but as they influenced me, I gradually came to disbelieve in Christianity as a divine revelation. The fact that many false religions have spread over large portions of the earth like wild-fire had some weight with me. Beautiful as is the morality of the New Testament, it can be hardly denied that its perfection depends in part on the interpretation which we now put on metaphors and allegories.But I was very unwilling to give up my belief... Thus disbelief crept over me at a very slow rate, but was at last complete. The rate was so slow that I felt no distress, and have never since doubted even for a single second that my conclusion was correct. I can indeed hardly see how anyone ought to wish Christianity to be true; for if so the plain language of the text seems to show that the men who do not believe, and this would include my Father, Brother and almost all of my friends, will be everlastingly punished. And this is a damnable doctrine.

My method is atheism. I find the atheistic outlook provides a favourable background for cosmopolitan practices. Acceptance of atheism at once pulls down caste and religious barriers between man and man. There is no longer a Hindu, a Muslim or a Christian. All are human beings. Further, the atheistic outlook puts man on his legs. There is neither divine will nor fate to control his actions. The release of free will awakens Harijans [lowest caste] and the depressed classes from the stupor of inferiority into which they were pressed all these ages when they were made to believe that they were fated to be untouchables. So I find the atheistic outlook helpful for my work [helping people]. After all it is man that created god to make society moral and to silence restless inquisitiveness about the how and why of natural phenomena. Of course god was useful though a falsehood. But like all falsehoods, belief in god also gave rise to many evils in course of time and today it is not only useless but harmful to human progress. So I take to the propagation of atheism as an aid to my work. The results justify my choice.

Christian missions to India imply that India is a land of heathens, and, therefore, stands on the same level with the Andaman or the Fiji Islands. That a country which has been recognised in all ages the world over as the mother of all religions and the cradle of civilisation should be considered as pagan, shows how much ignorance prevails in Christendom. Since the Parliament of Religions, I have been studying Christian institutions, and I have also studied the way in which the Christian ministers and the missionaries are manufactured in this country, and have learned to pity them. We must not blame them too severely, because their education is too narrow to make them broad-minded. I grant that they are good-hearted, that they are good husbands and often fathers of large families, but generally they are very ignorant, especially of the history of civilisation and of the philosophy of religion of India. Most of them do not even know the history of ancient India.We know that in this age of competition, centralisation, and monopoly, very many people are forced out of business. The English say, 'The fool of the family goes into the Church'; so that when a youth is unable to make a living, he takes to missionary work, goes to India, and helps to introduce among the Hindus the doctrines of his church, which have long since been exploded by science.
