- IDEA 1 OF 8
Progress can continue forever
Deutsch argues that the discovery of how to create good explanations, during the Enlightenment, began a process of progress that has no necessary limit.
He calls this the beginning of infinity.
- IDEA 2 OF 8
Good explanations are hard to vary
Deutsch argues that a good explanation is one whose details cannot easily be changed while still explaining the facts.
Myths, by contrast, can be altered freely without losing anything. A hard-to-vary explanation is more likely to be true.
- IDEA 3 OF 8
Problems are soluble
Deutsch argues that every problem caused by the laws of nature can, in principle, be solved with the right knowledge.
Problems are inevitable, but so is the possibility of solving them.
- IDEA 4 OF 8
Optimism is a stance
Deutsch defends optimism as the belief that failures come from a lack of knowledge, not from fixed limits.
He sees this as a rational, not wishful, position. Problems are solvable, he says, if the right knowledge is created.
- IDEA 5 OF 8
Some systems are universal
Deutsch explains universality, such as how a small alphabet can write any word or a computer can run any program.
He sees universality as a key to unlimited progress. A small set of parts can build endless variety.
- IDEA 6 OF 8
Societies can be static or dynamic
Deutsch contrasts static societies, which suppress new ideas, with dynamic ones that welcome criticism.
Only dynamic societies, he argues, sustain progress. In a static society, customs are kept as they are, and fresh thinking is discouraged.
- IDEA 7 OF 8
Ideas spread and evolve
Deutsch discusses memes, ideas that spread between minds.
He distinguishes ideas that spread by helping people from those that spread by disabling criticism. In this view, the useful question is whether an idea welcomes testing or blocks it.
- IDEA 8 OF 8
People are explainers
Deutsch argues that humans are special because we can create explanatory knowledge.
This makes people significant on a cosmic scale. Knowledge created by people can change the world, which gives them a special place in it.
