Do you know your Aristotelianism or Asceticism from your Egalitarianism? No? Well this book will give you all the information you need to tell one from the other and impress your friends with the seeming depth of your knowledge. Broken down by types of theory, from moral and ethical philosophy to aesthetics or reason (and with everything in between), this book brings together all the major theorists and arguments you should know, ranging back in time to the ancients and coming up to the modern day. Additionally, being organized by theory, it presents a potted overview of the timeline of Western philosophical thought and shows how theories from over 2,000 years ago are still relevant to our lives today.Jam packed with all the important ideas but at the same time highly accessible and informative, I Should Know That: Philosophy is perfect for those who enjoy thinking about the big questions in life.
