logic

is all logic based on either circular or axiomatic logic?

for example, "stop" is defined as
(of an event, action, or process) come to an end; cease to happen.

"cease" is defined as
come or bring to an end.

"end" is defined as
a final part of something, especially a period of time, an activity, or a story.

"final is defined as"
coming at the end of a series.

so it seems that you can't use dictionaries to understand words without knowing some words to start with.

maths is axiomatic and just uses some axioms which seem obvious (e.g. a+b = b+a) to construct the maths. but really, they aren't defined anywhere.

i don't know where i'm going with this. I guess I don't really know anything or know how anyone knows anything.
