In this book, you will find information about five different philosophers, some of them well-known, others less. But all of them had a significant impact on the ancient world and how people thought, as well as some of our modern-day ideas.

The first in line is Marcus Aurelius, a stoic emperor who reigned with righteousness and justice, according to historical records.

The second is Hipparchia, a cynic who broke through traditions and took a second look at society and its principles.

Third is a somewhat better-known historical figure called Heraclitus of Ephesus. This Greek thinker who noted that "life is flux", meaning that all things change constantly.

Fourth is Diogenes of Sinope, a Greek philosopher who was known for holding a candlelight to people's faces in search for honest people. His studies in Athens have left their mark.

The last this guide mentions and discusses, is Parmenides, founder of the Eleatic School of philosophy. He talked about the "way in which it is and the way in which it is not."

These wise theorists can inspire you if you let them. Go ahead and start reading the E-Book or listening to the audiobook.
