I was thinking about the euphoric sensation of insight, and sickness.
You can be desensitized to it. (LSD) Some aspect of insight is typical adaptation dynamics, but it isn’t clear that chemical tolerance is the only limit on insight.
There could be neurological limits, since there are actual neurological limits on how interconnected your brain can be. You don’t want to go schizophrenic or develop epilepsy.
Insight doesn’t have to be unique, and it clearly leaves a mark on your mind. It shapes your mind, and probably in ways that are well-precedented because the context of an insight depends on truth. But the side-effects of insight don’t inherently depend on truth. I want to be mentally unprecedented.
I was sick a few weeks ago. At the onset, in sharp contrast to previous days, I could not chase a single insight. Inflammation impedes insight.
But does it impede familiarity? If you wanted to have a non-insight comprehension of something, studying it only when you are sick could be a real advantage.
