Psychological instinct I believe is another term for gut instinct which can also mean intuition. Why then do some people have a stronger connection to their archetype than others? I agree with Jung that this cannot be learned, that you are born with a predisposition to hearing this inner archetype voice. The human experience repeats itself essentially comprising of the desire for love and to be loved, to reproduce and care for your family, for success, to be remembered. To leave your children better off than you what you achieved. But also there's the violent instinct to build an empire and then burn it to the ground. "Collective unconscious is a reservoir of psychic resources common to all humans" is a straightforward definition and a simple representation of this is you have an evil wolf and a good wolf which make up you, you need to feed the good wolf more often than the evil wolf to be a "good" person in life. The definition of empirically is "by means of observation or experience rather than theory or pure logic." (Oxford) The shadow in me is a selfish nature that I must consciously not feed to keep it in check. Anima is defined by its Latin derivation meaning "soul" for example Pandora. Jung uses this to describe the inner feminine side of men. Animus is also soul and a masculine side of females an example is Tarzan.
