Introduction
- Argument that all human progress has resulted from a single human activity: a quest for good explanations.
1 - The reach of explanations
- Scientific theories are not derived from anything, they are guesses.
- In reality the future is unlike the past. Science often brings with it experiences that have never been observed before in the past, based on predictions.
- No man steps in the same river twice, for it is not the same river, and he is not the same man.
- Fallibilism, or the idea that no authority has a final say on what is true, being aware that even our best theories have parts in them that are based on false truths, is essential for the beginning of infinity.
- We perceive nothing as what it really is.
- A tradition of criticism is crucial for scientific progress, to weed out bad explanations.
- Some explanations have enormous reach, explaining much more than what they were originally designed to.
2 - Closer to reality
- Scientific instruments bring us closer to reality, even when in purely physical terms they only ever separate us further from it.
- E.g. Looking directly at the stars there is only some air in between your eyes and the stars. With telescopes, mirrors, cameras, optical enhancers, & digital screens, you are further physically but can observe reality better.
- In a way, our senses are also only just instruments, the observation of reality still only happens in our minds. Senses just help us make a better approximate
3 - The spark
- We call a phenomena significant if parochial theories are inadequate to explain it, or if it appears in the explanation of many other phenomena.
