[analogy:] The normal way we conduct our lives is we reason by analogy. We are doing this because it’s like something else that was done, or it is like what other people are doing. Slight iterations on a theme.
[pattern:] Which is great, except when the pattern isn’t there, when our pattern-making machinery is busy picking things out that truly don’t matter.
[principles:] is a physics way of looking at the world. What that really means is that you boil things down to the most fundamental truths and then reason up from there.
