As a child, I was a slow learner. I had a bit of a flair for Maths, but not much else. By some fluke, I achieved exam grades that allowed me to study Maths and Computing at university. About the same time, I discovered the book Gödel, Esher and Bach which explored the relationship between Maths, Art and Music. I was hooked. Not only had I found my passion, but also a love of learning. This ultimately led me discovering the work of Oxford University theoretical physicist David Deutsch. A pioneer of quantum computing, he explores how science, reason and good explanations drive human progress. Blending physics with philosophy, David argues that rational optimism is the key to unlocking our limitless potential.

Ten insights from David Deutsch

Without error-correction, all information processing, and hence all knowledge-creation, is necessarily bounded. Error-correction is the beginning of infinity. - David Deutsch

The top ten insights I gained from David Deutsch are:

1. Wealth is about transformation. Money is just a tool. Real wealth is the ability to improve and transform the physical world around us.
2. All knowledge is provisional. What we know depends on the labels we give things. And those labels evolve.
3. Science is for everyone. We don’t need credentials to explore the world. Curiosity and self-experimentation make us scientists.
4. Stay endlessly curious. Never settle for shallow or incomplete answers. Keep digging until we find clarity.
5. Choose our people wisely. Avoid those with low energy (they’ll drag), low integrity (they’ll betray) and low intelligence (they’ll botch things). Look for people high in all three.
6. Learning requires iteration. Expertise doesn’t come from repetition alone; it comes from deliberate, thoughtful iterations.
7. Ignore the messenger. Focus on the message. Truth isn’t dependent on who says it.
8. Science moves by elimination. It doesn’t prove truths; it rules out falsehoods. Progress is the steady replacement of worse explanations with better ones.
9. Good explanations are precise. Bad ones are vague and slippery. The best ones describe reality clearly and in detail.
10. Mistakes are essential. Growth happens through trial and error. Every mistake teaches us what to avoid and that’s how we find the right direction.

Nietzsche said, There are no facts, only interpretations. Objective reality is inaccessible to us. What we perceive as truth is a product of our interpretations shaped by our cultural and personal biases. It struck me that Nietzsche and David Deutsch’s ideas closely align on this.
