What’s in it for me? Discover how doubt is an unknown, potent force in history.

What connects ancient philosophers like Socrates and Confucius with modern scientists like Einstein? They’re great thinkers, of course, but there is something more, something not mentioned as often as their original ideas and concepts. That something is doubt.

Throughout history, doubt and doubters have played a crucial role in the development of what we now know as the modern world. This doubt has been the spark for scientific innovation, a challenge to entrenched authorities, and the foundation for new religions. It’s been the source of despair and reassuring thought alike.

So how come we don’t hear about it? These blinks investigate what most history books ignore, and show us how doubt is about more than modern scepticism.

In these blinks, you’ll discover

  • why Giordano Bruno’s doubts led to his death; and
