The speeches and writings of American atheist orator Robert G. Ingersoll from the 19th century are collected in the book "The Works of Robert G. Ingersoll, Vol. 6". Politics, science, literature, and religion are just a few of the many subjects covered in the book. Ingersoll displays his mistrust of religion and promotes agnosticism throughout the whole book. He contends that religion, which he holds responsible for a number of global problems, is founded on irrational faith rather than on reason or solid facts. Ingersoll is in favour of a culture in which reason and science, rather than religious dogma, serve as the guiding principles. Along with criticising religion, Ingersoll also discusses a range of contemporary social and political concerns, such as women's rights, the role of the government, and the abolition of slavery. He believes that individuals should be free to live as they like as long as they do not damage other people, and he supports both individual freedom and freedom of thought and speech. Because of his eloquence, humour, and sense of reason, Ingersoll's lectures and articles were well-known throughout his lifetime. Readers and academics still read, discuss, and study them today because they are still relevant.
