Letters to Eugenia; Or, A Preservative Against Religious Prejudices

This book is an appeal against religious prejudices, especially that of a Christian nature, from the perspective of an atheist—the author, Baron d'Holbach. He was a French-German philosopher, encyclopedist, writer, and prominent figure in the French Enlightenment. He has written many books of a similar nature as this one, the most famous of them being 'The System of Nature' and 'The Universal Morality'.
