Joseph Conrad wrote the book, Heart of Darkness, in 1898. He wrote this book touching on many different themes such as imperialism and commerce, darkness imagery, dream and nightmare, isolation, mental and physical illness, truth, and journey. Although all the themes are important to make Heart of Darkness complete, three prevail overall: imperialism and commerce, truth, and journey. Being the author of the book, Joseph Conrad had a personal connection to it. He took his own journey down the Congo River and like Marlow, said that as a child his dreams were to grow up and explore the heart of Africa. A family member also recommended Conrad to a company. Joseph Conrad experienced the "heart of darkness", that could be a reason why his book is so in-depth.
