### Ideas to fill out as you review the book
- [Reach and Constraints](Reach%20and%20Constraints.md)
- can creationism be attacked on its own terms? Or simply that it’s a bad explanation? Or is it a philosophical argument (if you believe in creationism, you follow a different epistemology, and hence we can’t even argue)
- Pg 56, all regularities in nature have explanations - how do we know this?
### Chapter 5 - The Reality of Abstraction
Abstract entities are *real*, and can play a role in causing physical phenomena.
Causation itself is such an abstract entity.
#### Notes
Deutsch claims that something *abstract* - something non-physical, such as the knowledge in a gene or theory - is affecting something physical. Explanation at any level of emergence can be real an fundamental.
### A New Way to Explain Explanation
A bad explanation is easy to vary. A good explanation is hard to vary.
> The truth consists of hard to vary explanations of reality. This is the most important fact about the physical world.
### On Explanation
* Scientific explanations can be *falsified*. This is known as the *principle of falsification*
* [Wikipedia](https://en.wikipedia.org/wiki/Explanatory_power#:~:text=To%20Deutsch%2C%20the%20aspects%20of,avoid%20ever%20being%20truly%20falsified.) gives some great bullets. Specifically it states that a particular hypothesis, theory, or explanation can be said to have more explanatory power if:
* It accounts for more facts or observations
* It changes more surprising facts into "a matter of course"
* It offers greater predictive power
* It depends less on authorities
* It makes fewer assumptions (Occam's Razor)
* It is falsifiable (testable via observation or experiment)
* It is *hard to vary*
