It can also be seen as a philosophical doctrine which asserts that fundamental truths about the nature of reality are best discovered by reason and analysis of factual observations rather than any other method, such as faith, adherence to tradition, or careful study of existing doctrine or scripture.
What is the distinction between rationalism and positivism? The "key features" listed seem like a pretty definitive/universal explanation of how science works, which I would think would be a basic part of rationalism -- but perhaps there are rationalists who don't consider science to be essential?
- Rationalism holds that reason is the best method by which to derive knowledge.

- The concept of rationalization is often conflated with rationalism and rationality.
