“Umwege erhöhen die Ortskenntnis” (detours expand local knowledge) was a common saying of my philosophy professor after he went on a tangent during class.

I love the saying and I know the feeling pretty well – it frequently happens to me when I start to get interested in a topic. I start to research something, then I notice another interesting aspect, then another, and then another, and then… I guess you can see a pattern there. It’s similar to the process Dory experiences when she is trying to do something in Finding Nemo.
