How do we defined crazy?

[Angrboda]

Here's my first stab. Crazy, as a folk psychology, is when people act in a way that is both contrary to their own interests and harmful to others. If you put it into four-square it would look something like this:

self harm + other harm = crazy
self harm + other benefit = possibly genuine altruism or possible self-sacrifice
self benefit + other harm = evil
self benefit + other benefit = good

Only problems I see with this are, first, it's perspectivist. Who defines what harm is? Second, people are usually a complex blend of these, and different things at different times, so people have both self harm + self-benefit simultaneously, as well as other-harm and other-benefit simultaneously. And perspectivism applies to benefit as well. Are you less good because you're not trying to stop procrastinating so much? Moreover, the most important context in which these questions arise involve weighing one person's benefit against another's harm. This doesn't seem to scale very well.


And then you have people like me, who are truly crazy. I think self-harm is self-benefit and other-harm is other-benefit. Who are you to tell me that I am wrong?
