The Great Philosophers

Elder wisdom, Thinkers, and Creators Since Antiquity

Some say there’s nothing new under the sun. Maybe we don’t need to go that far — but we should definitely appreciate the voluminous contributions of the ancient thinkers and great philosophers of antiquity, who figured out a dizzying array of complicated concepts long before the modern era.

We have much to learn from our ancestral teachers. Here’s a place to start — which shall grow over time as the knowledge is passed down yet again, age unto age. Things that stand the test of time are valuable, no matter what the currency of the day.
