Introduction
Is free will an illusion or a biological mechanism? This article analyzes the anatomy of agency based on the thesis presented in the book Our Brains, Our Selves.
You will discover how neuroscience is redefining the concepts of responsibility and autonomy. The text explains that freedom is not the absence of causes, but rather a specific organization of the brain that allows for the self-correction of action.
Consciousness as Global Information Access
The author distinguishes between the mere experience of content and the ability to consciously utilize it. The former is phenomenal consciousness (the qualitative experience), while the latter is access consciousness, referring to data availability for working memory and behavioral control.
This distinction is crucial: one can experience a stimulus without being able to report it or use it to guide action. An example is the case of Winston, who maintained a state of wakefulness but lost access to parts of his spatial awareness.
According to Global Neuronal Workspace Theory, content only becomes conscious after so-called ignition, which enables its global distribution across brain networks.
Multiple Models of Consciousness and the Limits of Physicalist Explanation
Modern science offers various models of consciousness. Recurrent Processing Theory emphasizes the flow of information between cortical levels, while Integrated Information Theory links it to the internal causal structure of a system.
Higher-order theories suggest that consciousness requires a meta-representation of a cognitive state. Meanwhile, predictive processing models view it as the result of updating hypotheses about the world.
The primary limitation of these theories is the so-called 'hard problem' of consciousness. Explaining the mechanisms of data access does not explain why these processes are accompanied by the subjective feeling of what it is like.
Distinguishing Consciousness from Deliberative Agency
The author argues that Benjamin Libet's experiments do not rule out free will. The detected bereitschaftspotential (readiness potential) pertains to trivial movements, not complex decisions based on values.
The fact that the brain initiates processes before a conscious report does not mean that 'someone else' chose for us. A human acts through their brain; neuronal activity is part of the process of evaluating and preparing an action.
Freedom is therefore reasons-responsiveness, or the capacity of mechanisms to recognize reasons and alter behavior accordingly. Agency is not binary, but rather a gradable vector of competence.
Summary
Responsibility does not stem from a metaphysical independence from biology, but from the quality of the agent's causal organization. A loss of control due to illness changes the moral semantics of an act, but it does not necessarily negate the subject's dignity.
In the era of neurostimulation, the question of the limits of free will becomes a matter of design. The question remains open: how much can be changed in the brain's architecture while still being able to say: this is my life and my responsibility?
Frequently Asked Questions
What is the difference between the mere experience of something and the ability to consciously utilize that information in action?
This difference lies in the distinction between phenomenal consciousness (qualitative experience, e.g., color or pain) and access consciousness, which enables the use of information in reasoning, working memory, and behavioral control. While locally processed content can influence behavior unconsciously, only its global availability within the neural network allows for the flexible use of information by multiple processes simultaneously.
What are the main contemporary theories explaining the mechanisms of consciousness, and where do their limitations lie?
The main theories include Recurrent Processing Theory (consciousness as recurrent flow), higher-order theories (requiring a meta-representation of state), Integrated Information Theory (linking consciousness to information integration), and predictive processing theories. Their limitations stem from difficulties in falsifiability, a lack of full empirical confirmation (e.g., in the COGITATE project), and the inability to explain the so-called 'hard problem of consciousness'—namely, why physical processes generate subjective experiences.
Do Libet's experiments prove that the brain makes decisions before we do, thereby excluding free will?
No, such a conclusion is too strong relative to the provided experimental data. Libet's research concerned only the moment of initiating a trivial action, not deliberative control over an action or the realization of long-term plans and values.
Do studies on readiness potential and decision prediction prove that the brain decides before consciousness?
Not necessarily, because the readiness potential may result from the accumulation of random neuronal fluctuations rather than the making of an irreversible decision. Additionally, the measurement of the moment of conscious intent is questioned, and predictions regarding choices are statistical in nature and do not imply a predetermined future.
Does the fact that decisions are the result of brain processes exclude free will and responsibility?
No, because brain activity is not an external competitor to the subject, but part of the human decision-making process. Responsibility depends not on the absence of neuronal causes, but on whether the action originates from the person in an appropriate manner and whether the decision-making mechanism can recognize and account for reasons.
How do brain damages affect the assignment of criminal and legal responsibility?
Neurology can point to the weakening of specific brain mechanisms; however, it is law and ethics that decide on the assignment of guilt or sanctions. In criminal cases, what is essential is the capacity for understanding, intention, and behavioral control, rather than the mere fact of a neuronal cause for the act.
How does neurological knowledge influence the attribution of moral responsibility for specific actions?
Neurological knowledge does not replace psychological-behavioral criteria but complements them, altering the moral semantics of behavior through a new interpretation of the quality of the agent's will. It allows us to understand that certain acts may result from diseases or neurodegeneration, which can reduce the sense of attributing responsibility in cases where the ability to respond to normative demands is impaired.
Are free will and responsibility binary states, or do they depend on the specific cognitive abilities of the subject?
Free will and responsibility are not binary states; rather, they depend on the specific cognitive abilities of the subject and should be modeled as a vector of competencies. Agency depends on the quality of mechanisms such as reflection, simulating consequences, and conscious access to information in conflicting or uncertain situations.
Is the feeling that I am the author of my action identical to actual freedom and control over it?
No, the sense of agency is not identical to actual control. The introspective belief in the authorship of an action is not an infallible detector of causality and can be erroneous or weakened regardless of the actual influence on the outcome.
Does the loss of the ability to make responsible decisions mean a loss of human subjectivity and dignity?
No, the loss of the ability to make responsible decisions (moral agency) does not mean a loss of subjectivity or human dignity. Such a person remains a subject of protection (moral patiency), and decreasing autonomy increases the obligation of others to protect them.
Does the fact that our decisions have a neurological basis remove our responsibility for our actions?
No, the neurological basis of decisions does not remove our responsibility, because explaining the cause of an act is distinct from justifying an exemption from responsibility. Responsibility is linked to the quality of the agent's organization and their ability to recognize reasons and control reactions, rather than a metaphysical independence from biology.
What is free will from a neurobiological and functional perspective, and how does it translate into responsibility?
Free will is understood functionally as the degree of an organism's integrated ability to represent situations, respond to reasons, inhibit impulses, and learn from experience. In this view, responsibility is not a metaphysical issue, but a gradable assessment of the quality of agency, depending on the preserved neurobiological and cognitive competencies of a given person.
Are free will and responsibility possible in a world governed by biological causes?
Yes, free will and responsibility are possible because agency is a real level of organization within a complex bio-social system. Although actions have their causes, the appropriate organization of these processes enables the understanding of reasons, self-correction, and exercising control over one's own life.
