Over the centuries many great philosophers have written profound pieces that would be enjoyed by so many however the majority of the public is unable to do so. Most of the older Philosophy Topics written by philosophers such as Descartes, Newton and Kant are written in text that is largely unintelligible to us without the expertise. The oral and written language used centuries ago is very different with words that are no longer used today or words that are but have a different meaning. The sentences were long and complex and there is often difficulty with syntax. A few modern day philosophers have spent years translating the writings of these 16th-18th century authors into a version students can use today. With this translation works such as The Principles of Human Knowledge by Berkeley can be read by any who are interested and keen to do so and they will be able to understand the text.
