1. Physics
Early scientific thought often portrayed the universe as deterministic, and some thinkers claimed that the simple process of gathering sufficient information would allow them to predict future events with perfect accuracy. Modern science, on the other hand, is a mixture of deterministic and stochastic theories. Quantum mechanics predicts events only in terms of probabilities, casting doubt on whether the universe is deterministic at all. Current physical theories cannot resolve the question of whether determinism is true of the world, being very far from a potential Final Theory, and open to many different interpretations.
Assuming that an indeterministic interpretation of quantum mechanics is correct, one may still object that such indeterminism is for all practical purposes confined to microscopic phenomena. However, many macroscopic phenomena are based on quantum effects, for instance, some hardware random number generators work by amplifying quantum effects into practically usable signals.
A more significant question is whether the indeterminism of quantum mechanics allows for the traditional idea of free will (based on a perception of freewill - see Experimental Psychology below for distinction), when the laws of quantum mechanics provide a complete probabilistic account of the motion of particles regardless of whether or not free will exists. Under the assumption of physicalism it has been argued that if an action is taken due to quantum randomness, this in itself would mean that traditional free will is absent, since such action cannot be controllable by a physical being claiming to possess such free will. Following this argument, traditional free will would only be possible under the assumption of compatibilism; in a deterministic universe, or in an indeterministic universe where the human body is for all intensive neurological purposes deterministic.
Robert Kane has capitalized on the success of quantum mechanics and chaos theory in order to defend incompatibilist freedom in his The Significance of Free Will and other writings.
Ah physics not my strong suit and at a level several degrees above my pay grade. Standard egg head over thinking in my opinion. The gist of it appeared to be that since in theroy all possibilites could be predicted before hand we truly do not have free will, if I understood the gibberish correctly.
2. Genetics
Like physicists, biologists have frequently addressed questions related to free will. One of the most heated debates in biology is that of "nature versus nurture", concerning the relative importance of genetics and biology as compared to culture and environment in human behavior. The view of most researchers is that many human behaviors can be explained in terms of humans' brains, genes, and evolutionary histories. This point of view raises the fear that such attribution makes it impossible to hold others responsible for their actions. Steven Pinker's view is that fear of determinism in the context of "genetics" and "evolution" is a mistake, that it is "a confusion of explanation with exculpation". Responsibility doesn't require behavior to be uncaused, as long as behaviour responds to praise and blame. Moreover, it is not certain that environmental determination is any less threatening to free will than genetic determination.
Ah genetics at least I can grasp the concept. Basic gist is concering the effects of our genes have on our behavior. All in all it is just a cop out to excuss devient behavior. We are not animals and genetic errors can be overcome except in extreme cases.
3. Neuroscience
It has become possible to study the living brain, and researchers can now watch the brain's decision-making "machinery" at work. A seminal experiment in this field was conducted by Benjamin Libet in the 1980s, in which he asked each subject to choose a random moment to flick her wrist while he measured the associated activity in her brain (in particular, the build-up of electrical signal called the readiness potential). Although it was well known that the readiness potential preceded the physical action, Libet asked whether the readiness potential corresponded to the felt intention to move. To determine when the subject felt the intention to move, he asked her to watch the second hand of a clock and report its position when she felt that she had the conscious will to move.
Libet found that the unconscious brain activity leading up to the conscious decision by the subject to flick his or her wrist began approximately half a second before the subject consciously felt that she had decided to move. Libet's findings suggest that decisions made by a subject are first being made on a subconscious level and only afterward being translated into a "conscious decision", and that the subject's belief that it occurred at the behest of her will was only due to her retrospective perspective on the event. The interpretation of these findings has been criticized by Daniel Dennett, who argues that people will have to shift their attention from their intention to the clock, and that this introduces temporal mismatches between the felt experience of will and the perceived position of the clock hand. Consistent with this argument, subsequent studies have shown that the exact numerical value varies depending on attention. Despite the differences in the exact numerical value, however, the main finding has held.
In a variation of this task, Haggard and Eimer asked subjects to decide not only when to move their hands, but also to decide which hand to move. In this case, the felt intention correlated much more closely with the "lateralized readiness potential" (LRP), an EEG component which measures the difference between left and right hemisphere brain activity. Haggard and Eimer argue that the feeling of conscious will therefore must follow the decision of which hand to move, since the LRP reflects the decision to lift a particular hand.
Related experiments showed that neurostimulation could affect which hands people move, even though the experience of free will was intact. Ammon and Gandevia found that it was possible to influence which hand people move by stimulating frontal regions that are involved in movement planning using transcranial magnetic stimulation in either the left or right hemisphere of the brain. Right-handed people would normally choose to move their right hand 60% of the time, but when the right hemisphere was stimulated they would instead choose their left hand 80% of the time (recall that the right hemisphere of the brain is responsible for the left side of the body, and the left hemisphere for the right). Despite the external influence on their decision-making, the subjects continued to report that they believed their choice of hand had been made freely. In a follow-up experiment, Alvaro Pascual-Leone and colleagues found similar results, but also noted that the transcranial magnetic stimulation must occur within 200 milliseconds, consistent with the time-course derived from the Libet experiments.
Despite these findings, Libet himself does not interpret his experiment as evidence of the inefficacy of conscious free will—he points out that although the tendency to press a button may be building up for 500 milliseconds, the conscious will retains a right to veto that action in the last few milliseconds. According to this model, unconscious impulses to perform a volitional act are open to suppression by the conscious efforts of the subject (sometimes referred to as "free won't"). A comparison is made with a golfer, who may swing a club several times before striking the ball. The action simply gets a rubber stamp of approval at the last millisecond. Max Velmans argues however that "free won't" may turn out to need as much neural preparation as "free will".
Basic gist that under lab conditions the brain appears to make a decision before the conscious mind. If I understood the excerpt correctly it was more of a rapid response unit, the concionus mind still exercises control.
4. Neurology and psychiatry
There are several brain-related conditions in which an individual's actions are not felt to be entirely under his or her control. Although the existence of such conditions does not directly refute the existence of free will, the study of such conditions, like the neuroscientific studies above, is valuable in developing models of how the brain may construct our experience of free will.
For example, people with Tourette syndrome and related tic disorders make involuntary movements and utterances, called tics, despite the fact that they would prefer not to do so when it is socially inappropriate. Tics are described as semi-voluntary or "unvoluntary", because they are not strictly involuntary: they may be experienced as a voluntary response to an unwanted, premonitory urge. Tics are experienced as irresistible and must eventually be expressed. People with Tourette syndrome are sometimes able to suppress their tics to some extent for limited periods, but doing so often results in an explosion of tics afterward. The control which can be exerted (from seconds to hours at a time) may merely postpone and exacerbate the ultimate expression of the tic.
In alien hand syndrome, the afflicted individual's limb will produce meaningful behaviours without the intention of the subject. The clinical definition requires "feeling that one limb is foreign or has a will of its own, together with observable involuntary motor activity" (emphasis in original). This syndrome is often a result of damage to the corpus callosum, either when it is severed to treat intractable epilepsy or due to a stroke. The standard neurological explanation is that the felt will reported by the speaking left hemisphere does not correspond with the actions performed by the non-speaking right hemisphere, thus suggesting that the two hemispheres may have independent senses of will.
Similarly, one of the most important ("first rank") diagnostic symptoms of schizophrenia is the delusion of being controlled by an external force. People with schizophrenia will sometimes report that, although they are acting in the world, they did not initiate, or will, the particular actions they performed. This is sometimes likened to being a robot controlled by someone else. Although the neural mechanisms of schizophrenia are not yet clear, one influential hypothesis is that there is a breakdown in brain systems that compare motor commands with the feedback received from the body (known as proprioception), leading to attendant hallucinations and delusions of control.
Also, obsessive-compulsive disorder and other compulsive behaviour, such as compulsive overeating and addiction, may be linked to a lack of free will. And only hints, or degrees, of this may be linked to a lack of totally free will.
Gist refers to how people with damaged mental systems uncontrollable do things. All it seemed to prove is that some people have faulty wiring, some due to no fault of thier own and others self-inflicted. I see no argument against free will anymore then a person with a broken spine would be.
5. Determinism and emergent behaviour
In generative philosophy of cognitive sciences and evolutionary psychology, free will is assumed not to exist. However, an illusion of free will is created, within this theoretical context, due to the generation of infinite or computationally complex behaviour from the interaction of a finite set of rules and parameters. Thus, the unpredictability of the emerging behaviour from deterministic processes leads to a perception of free will, even though free will as an ontological entity is assumed not to exist. In this picture, even if the behavior could be computed ahead of time, no way of doing so will be simpler than just observing the outcome of the brain's own computations.
As an illustration, some strategy board games have rigorous rules in which no information (such as cards' face values) is hidden from either player and no random events (such as dice rolling) occur in the game. Nevertheless, strategy games like chess and especially Go, with its simple deterministic rules, can have an extremely large number of unpredictable moves. By analogy, "emergentists" suggest that the experience of free will emerges from the interaction of finite rules and deterministic parameters that generate infinite and unpredictable behaviour. Yet, if all these events were accounted for, and there were a known way to evaluate these events, the seemingly unpredictable behavior would become predictable.
Cellular automata and the generative sciences can model emergent processes of social behavior on this philosophy.
Similar to the quantum theroy. All events could be predicted before they occur by knowing all variables etc. I still don't quite understand the relationship. You can have the probability I will do something but that is all. The will to act or not to act still rests with me.
6. Experimental psychology
Experimental psychology's contributions to the free will debate have come primarily through social psychologist Daniel Wegner's work on conscious will. In his book, The Illusion of Conscious Will[88] Wegner summarizes empirical evidence supporting the view that human perception of conscious control is an illusion. Wegner observes that one event is inferred to have caused a second event when two requirements are met:
The first event immediately precedes the second event, and
The first event is consistent with having caused the second event.
For example, if a person hears an explosion and sees a tree fall down that person is likely to infer that the explosion caused the tree to fall over. However, if the explosion occurs after the tree falls down (i.e., the first requirement is not met), or rather than an explosion, the person hears the ring of a telephone (i.e., the second requirement is not met), then that person is not likely to infer that either noise caused the tree to fall down.
Wegner has applied this principle to the inferences people make about their own conscious will. People typically experience a thought that is consistent with a behavior, and then they observe themselves performing this behavior. As a result, people infer that their thoughts must have caused the observed behavior. However, Wegner has been able to manipulate people's thoughts and behaviors so as to conform to or violate the two requirements for causal inference.[88][89] Through such work, Wegner has been able to show that people will often experience conscious will over behaviors that they have in fact not caused, and conversely, that people can be led to experience a lack of will over behaviors that they did cause. The implication for such work is that the perception of conscious will is not tethered to the execution of actual behaviors. Although many interpret this work as a blow against the argument for free will, Wegner has asserted that his work informs only of the mechanism for perceptions of control, not for control itself.
Basic gist is the altering of perception. All this proves is our senses are imperfect and that our mind can be exploited.
As you see, it is not as simple to prove that you have a free will
I already told you, I know I have free will. If you choose not to that is your choice but I alone decide my fate.
to prove that animals have no free will
They don't. They are slaves to thier instincts.
to reason that because animals have no free will
The emperical evidence of zero point zero lower based animals displaying reasoning ability precludes them from being able to reason regardless of the existence of free will or not.
they are less valuable than humans.
They are less valuble as we all have shown. A human is self-aware, can reason and at the very least has the simulation of free will. The animals have not.
And I recommend to read that text carefully. Because, if you claim that the professors in the text above have all the same opinion, you create the impression that you have not really read that text because their opinions how to approach that problem are totally different.
The previous text did all have the same opinion. That animals and humans are equal they just had slightly differnt methods are reaching the same destination. All based upon the same faulty assumptions. As for these texts they cover a wide range of of opinions and fields and no they do not have the same opinion mostly because several of them have nothing to really do with free will.
And that is exactly the interesting thing: That with different approaches they get the same outcome.
Actually they range from this might mean there is no will if my theroy which we can not yet verify is correct to I can alter the perception of my test subject to some people curse against thier will. This is the evidence that swayed you?
That could be a sign that they can't be too wrong.
The work you cited does not collaberate that statment when they don't even know for sure what thier results mean.
And yes, I understand the problem you may have. It is difficult to accept that one is not the navel of the world - as we say in Germany. That's why such considerations have a huge opposition. But feminists did also have a huge opposition and today we all know that they were correct.
I truly do not know what to say. You appear to have fully jumped onto this theroy without thinking it through, despite basing it in part on predicting the future you appear blind to what this theroy would mean if it was in fact correct. The destruction of the human race as thier existence becomes a bad joke. Why work or do anything? Your fate is preordained from the cosmos if something is to happen it will happen. Humanity would shuffle off the mortal coil binging on every vice and leave nothing but bloated corpses in thier wake. The really sad part it still wouldn't make a person equal to a *spit* animal. Do you really think a dog spends vaste sums of money, time and resources proving that life is a mirage? All you have done is proven how we are superior to our four legged friends which I find deeply ironic.
As I said WILGA in the end each man must answer the question for himself. This isn't something a scientist can help you with, much less with unconfirmed theroys regarding a possible interpation of the data. When you look into the mirror to shave every morning and you look into the eyes of the man staring back you decide. Embrace your life WILGA or assume it is all an illusian to trick you but only you can. I couldn't live not being the master of my fate but if you want that I hope you can.
