Determinism: Can Scientific Explanations Explain Human Behaviour?

Click For Summary

Discussion Overview

The discussion revolves around the concept of determinism and its implications for understanding human behavior, particularly whether scientific explanations can fully account for human actions and decisions. Participants explore the intersection of determinism, quantum mechanics, and the complexity of human consciousness, touching on philosophical perspectives and scientific theories.

Discussion Character

  • Debate/contested
  • Conceptual clarification
  • Exploratory
  • Technical explanation

Main Points Raised

  • Some participants suggest that strong determinism implies the universe is fundamentally predictable, where resetting a system would yield the same outcomes, but practical limitations challenge this view.
  • Others argue that observing a system without altering it is likely impossible, raising questions about the feasibility of monitoring complex systems without interference.
  • There is a discussion on quantum randomness, with some noting that classical physics allows for deterministic descriptions, while quantum mechanics introduces probabilistic elements that complicate predictions.
  • One participant raises the issue of emergence, arguing that higher levels of complexity can produce new causations that a lower-level deterministic model cannot adequately capture.
  • Another participant expresses uncertainty about formal philosophical determinism, distinguishing it from fatalism and emphasizing the impact of individual actions on outcomes.
  • Some participants propose that consciousness may still emerge as a property of complex systems, regardless of deterministic or probabilistic frameworks, and that the illusion of free will persists in practical terms.

Areas of Agreement / Disagreement

Participants do not reach a consensus, as multiple competing views on determinism, emergence, and the nature of human behavior are presented, with ongoing debate about the implications of these theories.

Contextual Notes

Limitations include unresolved questions about the accuracy of initial conditions in deterministic models, the nature of emergence in complex systems, and the philosophical implications of determinism versus free will.

So taking that view, where do fundamental dynamical laws come from?
Imo, that would be an unanswerable question.

apeiron said:
From a practical epistemological point of view, you can just shrug your shoulders and say "they exist".
Yes. A fundamental dynamical law (or laws) would be assumptions. But it seems to me that that approach implies that our universe is evolving deterministically. That is, lawful evolution = deterministic evolution.

apeiron said:
But from a metaphysical and ontological point of view - which was the OP - you would want to be able to explain how laws arise as your global constraints.
Can global constraints be explained in terms of an assumed general dynamical law (or laws) without explaining the origin of the dynamical law (or laws)?

apeiron said:
So you are talking about organising principles that arise at some level. You seem to find that uncontroversial.
I think it's been pretty well established. Eg., the understanding and control human behavior is done, for the most part, at the macroscopic level of human behavior, and not at the submicroscopic level of subatomic particles, or in terms of wave mechanics. But then, scientists have found many connections between the mesoscopic realm and the realm of human behavior. And there are interesting connections between the mesoscopic the microscopic, and between the microscopic and the submicroscopic. All of which leads me to think that there might be some sort of fundamental dynamical law or laws at work.

apeiron said:
But why would you stop there and not extend this to the idea of global organising principles that arise at the global level (and so are all-encompassing as they act on every scale in downward causal fashion).
Exactly. This is what the assumption of a fundamental dynamical law (or laws), encompassing any and all scales of behavior, would do. But this isn't the current paradigm of fundamental physics.

If scale specific organizing principles can emerge, we may have to rethink the notion of purposeless reality and existence.
Why? The notion that scale specific organizing principles have emerged from, say, countless iterations of a fundamental wave mechanical dynamic would seem to me to obviate teleological explanations.

Maui said:
I don't think anyone entertains the idea that something as sophisticated as an Airbus A380 was an inevitable occurrence in nature.
If one assumes a lawful universe, then whatever exists in that universe is an inevitable consequence of the initial conditions and the evolutionary laws.

And given that the brain, even if we view it as a machine, is a really, really complex machine - the most negentropic concentration of matter in the known universe - then where is the heat in the argument? Our own neural complexity makes us hugely isolated from the simplicities of the physical world, especially from the highly generalised view we take of the microscale in our material theories.

So how much freedom is enough freedom? Do we need absolute freedom from external constraints? Do we need absolute freedom from our own developmental past (in the shape of accumulated habits and expectations)? Do we need absolute freedom from physical simplicity?

I am not worried, I am pointing out the old debate on whether we are 'zombies' or not. We either have free will, or we don't, and the latter case is philosophically lousy since that would imply that we don't have responsibility for any actions we take. The amount of complexity of the system, or the amount of freedom, is irrelevant.

I.e., if you are a robot/zombie/fully deterministic and you go out and kill someone, nobody can really blame you for it since you have no free will, you are just running a program. No free will would kill off all ethical considerations since nature/physics doesn't have ethics, only laws.

Most scientific evidence points at that we don't have free will, so it's free game for everyone since there are no ethical considerations. Of course, it doesn't work that way, but at the moment the natural sciences tell us is that human behavior is pre-programmed, devoid of free will, therefor things like ethics are an illusion.

Responsibility is a human-level imperative, the practical consideration of which is independent of whether or not what we call free will is a function of a deterministic or indeterministic universe.

I agree.

The concepts and practice of responsibility and ethics are behavioral controls, not illusions.

You equated ethics to behavioral controls which -historically/philosophically- means that there are no ethics, only laws of nature. Behavioral controls follow no guidelines except for those (pre-)programmed, the term ethics becomes meaningless in that context.

I meant man-made behavioral controls. In which context the terms ethics and responsibility are meaningful.

Oh, well, only in a context of free will. :biggrin: Fortunately, personally, as an absurdist, I believe life cannot be understood. So to me it's an whatever.

It's also possible to be an absurdist in a deterministic universe. :smile:

While it may not be possible for a human to understand the physics behind an experiment enough to predict it fully I wonder if it's possible for the universe? Or more to the point could it be possible even the laws of physics them selves do not fully "understand" what will happen in an event with 100% accuracy? I think it would be interesting if someday in the future scientists found this to be the case.

Thats pretty much the definition of determinism.
