Everyday, we benefit from huge advances in both scientific theory and practice. What triggered this progress?

Human creativity opens up limitless opportunities for progress, making knowledge the “beginning of infinity.”

Aristotle’s Way (2018) is a study of Aristotle, philosopher and polymath of Ancient Greece – but it’s not a scholarly guide to a historical artifact. Aristotle is simply far too alive to be relegated to that category. Friendship, happiness, talking, thinking, and living well were Aristotle’s great concerns. And what he had to say about those topics remains every bit as relevant today as it was when he first started exploring them some 2,500 years ago. 

Man and His Symbols (1964) was the final work of the influential psychologist Carl Jung, and the only one written for a general audience.
