Deterministic processes do affect our environment but hasn't been determined to be the cause of any human behavior.
The "enviroment" is a finite set of "determnistic processes". No environment then no human. No "determinsictic proceesses" then no human.
(1) human behavior is in direct contrast to how deterministic processes behave.
Humans access to metaphysical-1, mind/intellect/concepts and ego, are direct synergetic resultant and the source of the illusion of free will, and at best limited free will. Free will illusion cannot violate the finite set of cosmic laws/principles.
(2) quantum mechanics shows that reality is indeterminate unless observed. This, if true, proves that determinism is wrong.
Uncertainty need not necessitate chaos of mind. Occupied space reality { physical/energy } aka Observed Time, is a resultant of underlying set of occupied space of metaphysical-3 ultra-micro gravity ( ) and metaphysical-4, dark energy )(.
(3) people prima facie have free will.
A very good illusion of finite free will is still an illusion and no differrent then a very good magican performing illusion of magic.
The true magic is that we have the mo-jo of mo-tion. We have top speed-of-motion and it remains a mystery as to how that speed appears as a contant irrespective of the observer.
(4) determinism can't be a rationally held belief if it's in fact true. We would all be pawns of mindless forces, installing thoughts and behaviors into us as chemical reactions. Mindless forces that are doing all of the controlling are not rational and possess no understanding.
Replace your use of the word "mindless" with integral forces having a magnitude and direction of vector.
That we cannot quantise or quantify the force does not make less the effects we observe.
Humans do not have any elemental force within them, that we can assoicate with limited free will, that is not any one or more of the elements we find elsewhere in Universe.
(5) if determinism is true, people have no moral culpability. Prima facie people have moral culpability.
Yes they do because humans have adopted morals into our life mechanics, irrespective of whether free will is a very good illusion.
(6) cause and effect are not violated if free will exist due to mental causation.
A very good illusion of limited free will, remains a very good illusion, irrespective of how many of the fermons and bosons we can quantise, quantify as a whholistic maping of all lines-of-relationship assocated directly or indirectly to every motivating choice { desire } or desire { emotion } that moves us.
Sitting at table, the brain processes { mo-tion } recalled { mo-tion } and event { mo-tion } and a critical amount of occupied space chemistry moved me to move { get out of the chair }.
Woman { Xx }//Attracter with seeming static egg X sitting around doing nothing. Just waiting for the egg X to fall { gravity? | through the fallopian tube into the uterus.
Man { Xy }//Pusher sends spermazoa on its pathway to the egg X.
The scene is set in motion ---it was never static to begin with--- as they come after all of the previous lines-of-relationship vectors//desires that led these two to this confluence of emotional resultants of a fertilized egg { * * } that has not yet adopted and ego. Or has it?
Children do not usually distingush between left and right untill their abaout 8 years old. When does the fetus identify with its ego?
Mo-mma's chemistry attracts Papa's chemistry. Love Motion//Potion #9
Egg chemistry attracts spermazoa chemistry. Love motion//potion of chemistry { charge }
RNA-DNA >< RNA-DNA combining and multiplying { motion } as a dynamic{ motion } cell and mo-cells.
More willd motions for 9 gestation months
Mo-mma's uterus muscles contract IN-ward and fetus//baby is pushed-OUT. SHazam!
Breath Baby Breath, clean out the airways and induce breathing with spank { motion } on the buttocks.
Wahh! Wahh! Give that baby some nipple { supple motion } and see if it will stop Wahhing.
So now baby knows enough Wahhing may have good tasting nourishment { milk }. Ego developes.
Cry suckle, cry suckle cry suckle Motion begats motion.
i desire > suckle > i desire > suckle > i desire > suckle baby ego { i } plus motion ego not skewed
i desire > Sex > i desire > Sex i desire > Sex > teens ego { i } plus motion with ego partially skewed
I desire to be God > I desire to be God > adult narrcist ego { I } plys motion with ego greatly skewed
Death aka terminal ending of biological life, and end of local-case//special-case ego
