I am wondering to what extent is human passion attributable to the endocrine system only? (I don’t mean just sexual passion. I mean also love of art, various sentiments, political convictions, love of music, etc.)
I understand that without an endocrine system, you are dead… but if one’s hormones are compromised in some way, does it affect one’s capacity for such feelings? Conversely, what about if one’s intellect is compromised?
I’m asking because I have an older friend who says he used to like certain kinds of music back when he had raging hormones; but now, not so much.
Thanks.

I think this is one of those cases where the standard scientists’ disclaimer: “Correlation is not causation” applies - at least where hormones are concerned. I think you could find considerable evidence that people’s tastes do change as they get older, whether it’s the transition from adolescence to adulthood, or from one adult stage of life to another. Our experiences sometimes change our attitudes; this much is obvious. But in general, those changes result from life experiences, not from biological changes. A common example is how so very many people’s political preferences change over their lifetimes (my father was a fairly extreme example of this).
Where music is concerned, I go through periods when I enjoy one type of music more than another, but I’ve never reached a point where I found a musical genre I’d once loved no longer enjoyable. If it’s something I’ve loved, sooner or later I’ll enjoy - even prefer - it again; it’s happened repeatedly. Yes, I’m a musician, but I don’t think that makes a difference.
I have read some reports of studies that claim that alterations in a person’s brain affect their preferences in a variety of different fields. ISTR there is a book about personality changes resulting from injuries or other alterations in brain function, but I can’t recall the name of it right now.
It is possible that your friend has had one or more mini-strokes, and that those are responsible, if you insist on some kind of alteration in his body being responsible for the change in his musical tastes. Mini-strokes can be perfectly “silent” - IOW, undetectable, in the absence of “gross” changes in behavior, or physical or mental capacity.
Other than that, I dunno. Of course, IANA doctor, nor am I member of any of the other professions who have made particular study of the mind/brain, just a science junkie with an academic background in biology and anthropology.
