philosophy is just manifested psychology
all philosophy is just a manifestation of some ones psychological make up
realism
idealism
deontology
nihilism
etc
say more about a persons mental state than any thing about reality etc
your philosophy is just you projecting your psychology onto the world
No, it’s more of a manifestation of the person’s physiology.
Good point. Physiology → Psychology → Philosophy
Here’s my take: physiology & psychology & sociology = personal philosophical identities (-ists, -isms)
So what?
true. For we are primarily spirits. And everything we create is an extension of our inner being. Even the scientific method was created as a process of finding acceptable thought in one mans eyes.
physiology → environment → psychology → philosophy
More like: environment → physiology → psychology → philosophy 
I actually wanted to put history in there because the time period in which you happen to live often influences your perspective on things (your view of life). Something like social/historical environment, perhaps. For example, if I were born about 300 years ago I would probably have had a slightly different view of life (as a woman). You can see this difference in thinking every time you talk to your grandparents, or other old folks you happen to talk to.
Who made who?
Spirit,… transending through brain…
Brain limiting perception of reality,… which effects demeanor.
Demeanor determins how you react to obsticals. How you view and obstical changes how you treat the problem.
How you treat the problem changes what the problem becomes.
What the problem is physically, is spiritually created.

it all stems from the heart.
I consider the period you live in as part of the environment. nature + nurture = environment.
