Freedom
Freedom of human action requires the randomness of absolute chance to break the causal chain of determinism, yet the conscious knowledge that we are adequately determined to be responsible for our choices.
Freedom requires some events that are not causally determined by immediately preceding events, events that are unpredictable by any agency, events involving quantum uncertainty.
These random events generate alternative possibilities for action.
They are the source of the creativity that adds new information to the universe.
Randomness is the “free” in free will.
Freedom also requires an adequately determined will that chooses or selects from those alternative possibilities. There is effectively nothing uncertain about this choice.
Adequate determinism is the “will” in free will.
Adequate determinism means that randomness in our thoughts about alternative possibilities does not directly cause our actions.
Random thoughts can lead to adequately determined actions, for which we can take full responsibility.
We must admit indeterminism
but not permit it to produce random actions
as Determinists mistakenly fear.
We must also limit determinism
but not eliminate it
as Libertarians mistakenly think necessary.
Event acausality is a prerequisite for any kind of agent causality that is not pre-determined.
When philosophers in the 1920’s looked at the newly discovered quantum uncertainty principle as a means of breaking the iron grip of determinism (actually many determinisms), they found it most unsatisfactory.
If my action is the direct consequence of a random event, I cannot feel responsibility. That would be mere indeterminism, as unsatisfactory as determinism. For some philosophers, any indeterminism threatens reason itself. Reason seems to require strict causality and perfect certainty for truth.
Determinism and indeterminism are the two horns of the dilemma in the standard argument against free will, which is seriously flawed.
Arthur Stanley Eddington, a scientist who understood the quantum mechanics, and who hoped it would throw light on the problem of free will, accepted the standard argument and declared “there is no halfway house” between randomness and determinism.
We propose a model of human freedom that is a halfway house between chance and necessity, one that involves both, first indeterminism to generate free alternative possibilities, then adequate determinism to choose, to will one of those possibilities.
Without this freedom there can be no explanation for human creativity, which brings unpredictable new information into the universe, “something new under the sun.”
Our mind model invokes quantum uncertainty to provide an “Agenda” of unpredictable thoughts and actions, critical to both freedom and creativity. We call this the “Micro Mind,” but it not in a particular location in the brain. The Micro Mind describes the brain’s information processing systems, the storage and retrieval of actionable information, communicated by structures small enough to be affected by quantum uncertainty, by quantum and thermal “noise.”
The “Macro Mind” examines the agenda and chooses what to do or say based on its character (past actions and feelings) and its values. The Macro Mind has evolved to suppress the microscopic low-level noise. It averages over vast numbers of atoms and molecules in a large enough physical structure to be highly predictable - adequately determined - its choices are in practice unaffected by quantum uncertainty.
Our mind model uses random noise when it needs it for imagination and creativity, but suppresses noise whenever it needs to for consistent behavior and responsibility.
soft causality, but no strict determinism Our model eliminates the perfect certainty associated with many strict determinisms). Nevertheless, we retain the very important concept of causality - despite the fact that some events are unpredictable from prior events. The world contains an irreducible quantum indeterminacy.
Each event, as an effect, still has its causes. But some causes are now what ancient philosophers called a causa sui, a cause that includes itself among its causes. This modified or “soft” causality contains the mixture of unpredictability and predictability, of indeterminism and adequate determinism, of acausality and causality, that we need for freedom and creativity on the one hand and responsibility for our actions on the other.
In our history of the free will problem, we have found that many great thinkers have anticipated this two-stage solution to the classical problem, among them William James, Henri Poincaré, Arthur Holly Compton, A.O. Gomes, Karl Popper, Henry Margenau, Daniel Dennett, Robert Kane, and Alfred Mele.
Mele describes the importance of the temporal sequence quite clearly, though he remains agnostic on the truth of determinism and does not see (as others did not see) a location of indeterminism in the brain that does not compromise agent control.
