Psychology Philosophy Interface

Psychology Philosophy Interface

While reading the threads here (and noticing an overwhelming amount of psychology threads over philosophical ones) I was thinking constantly: how much psychology took from philosophy and if the inverse happened (with Foucault being the only one who talked about this specifically).

Also, extending the question scope, how my philosophers have to learn with psychologists? And the inverse?

I know it is not a very detailed topic, but it is only a reflection of mine on the topic. What do you guys think about it?
