Chapter 1: Understanding the Debate

The question of whether physical laws inherently conflict with free will has long been a topic of philosophical discussion.

In the realm of consciousness studies, Benjamin Libet, a prominent psychologist, demonstrated that brain activity can be detected approximately 300 milliseconds before an individual consciously perceives the decision to act. This raises intriguing questions about the nature of consciousness and the validity of free will.

To navigate this complex terrain, we must consider the implications of these findings. Many might conclude, from a determinist viewpoint, that our actions are dictated by the biological framework of our brains, rendering free will an illusion within the confines of natural laws.

Is this perspective truly accurate?

While it's evident that our consciousness emerges from the intricate workings of our brain’s neural networks, the relationship between brain activity and the sense of free will is not straightforward. For instance, during the time when brain scans highlight activity related to a simple action, like lifting a finger, could it be possible that an individual momentarily contemplates refraining from that action? Or conversely, could the thought of lifting a finger arise simultaneously with the brain's decision-making process? The implications of these scenarios warrant further exploration.

If we consider the first scenario, where an individual thinks about not lifting their finger just before the brain initiates the action, it suggests that the brain may override conscious intentions. This creates a paradox: on one side, the individual feels that they have made a conscious choice, yet this sensation is essentially a byproduct of a predetermined brain decision made prior to their awareness.

This leads us to a peculiar form of dualism, where one’s consciousness appears to be split: the brain operates autonomously, crafting an illusion of a self-aware individual that believes it is making decisions, while in reality, these decisions are preordained.

What evolutionary advantage could such a dual-consciousness provide? Given that the brain evolved in response to vastly different environmental conditions, how does it justify making choices—like selecting between a laptop and a smartphone—independent of our conscious experience?

The thought experiment known as “Brain in a Vat,” proposed by Hilary Putnam, provides a compelling illustration of the divide between the brain and the self. Imagine a brain connected to a supercomputer, experiencing a simulated reality. According to Libet’s findings, decisions would occur before the self becomes aware of them, all within a virtual environment.

This scenario raises further questions: if the self only exists within the confines of the simulation, how can it make decisions independent of the predetermined code? Clearly, this thought experiment challenges the distinction between brain and self, suggesting that a deeper understanding of consciousness is necessary—one that neither fully endorses determinism nor posits a separation between mind and brain.

Interestingly, this exploration indicates that free will may coexist with determinism. For example, consider a pilot navigating through unpredictable weather conditions. Despite external influences, the pilot retains the capacity to make choices, akin to the experience of free will. In this analogy, the mind is represented by the plane, while the brain reflects the unpredictable forces of the environment.

Ultimately, I propose that I am my brain, my brain is my self, and the self actively engages in decision-making, reflecting on experiences, and weighing options. The Libet experiment primarily examined involuntary actions, which I believe do not encapsulate the essence of true freedom or the act of willing. Instead, I contend that a case for compatibilism—the harmonious coexistence of free will and determinism—should be advocated.
