The question is, has he originated a completely new philosophical system as did Plato and Aristotle? Or has he brought his extensive knowledge of history and the wisdom literature to reframe what the great thinkers have been saying for centuries? I would say both. He is not an originator. He is a re-interpreter.
From his standpoint of enlightenment he can take any great system of thought and spirituality, such as Taoism, Stoicism, Buddhism, Sufism, and show us ways to see them in a new light.
When Plato originated his unified view of the world he constructed it from the time he spent with his teacher, Sophocles. And Aristotle, who was Plato’s student also used his great teacher to help him build a foundation for his musings on the nature of existence. Eckart Tolle is like both Plato and Aristotle, in that he builds on a foundation that has been paved by others.
Eckart Tolle has brought fresh eyes to ancient wisdom. Because of his intense spiritual experiences and ability to communicate them, he is of tremendous benefit to those who are unsettled by the effects of the ego mind. He explains, in inspired language, the clear paths to inner peace and living in the present moment. And because he reveals so much of his personal struggle, unlike the ancients who so far removed from us, we can connect with him and grasp his teachings.
