"Epistemology" is the subject matter that deals with truth on a meta level: e.g., questions such as "What is truth?" and "What methods of reasoning are most likely to lead to true beliefs?" Epistemology can be considered as a child subject of Rationality. Many Arbital Discussion Practices have their roots in a thesis about epistemology - about what forms of reasoning are most likely to lead to true beliefs - and you may have ended up looking at this subject after trying to track down how a Discussion Practice is justified.

I'm noticing a trend of pages with titles that start with a lower case letter. Is that on purpose? Should I add a line of code to always capitalize the first letter?

I think my intent was something like, "lowercase things are simple concepts, capitalized things are more complicated theories or propositions".

Okay. I hope to do that with meta tags in the future, e.g. "stub".
