Sorry, I shouldn't have brought up 'ends' in human sciences. I was rambling. All I meant was things like psychology, sociology, economics not to mention things like ethics, or whatever may have very different methodologies due to the subject being people, and in human sciences it's a lot more intuitive and obvious to have final causes. That's all I meant. It would probably be a lot easier to have all four causes in use in these subjects.Are you saying that biology doesn't study human subjects?
I am saying that psychology, sociology, etc may be more required to take human decision making, emotions, values, goals, and the like into consideration and are more equipped to do so than a "hard science" such as biology (which studies humans).
If this is still nonsensical to you, sorry...I'll try to clear it up tomorrow, I've been out tonight.
