Finished this book last night. A little on the brighter side of the spectrum. Eco's work on language, 5 essays concerning its roots, is almost master's homework. The work is, at times, very interesting and mind-blowing. His focus on the pre-Tower of Babel language was especially fascinating, bringing to light multiple authors and inventors I had never heard of prior to the essay. But, at just as many times, the book is as clear as mud. Eco is brilliant, a master of language, and I am not. I imagine it would be like trying to discuss the subject with him, it would be boring for both he and I, simply because we are moving on different levels.
However, don't let that last comment make you fearful. Read the book and try to grasp what he is saying. Stretching your mind is the only way to strengthen it. Push your limits, read this book.
