Based upon many posts I concluded that there is a lot of misunderstanding floating around about materialism. In quite a few threads there are posts, which do not belong to the topics over there, they keep questioning materialism.
I welcome your questions. I will try my best to clarify some issues.
Okay, I’ll bite.
How can a materialist find support for ethical judgements in non-thinking, non-planning, non-judging matter?
Stated otherwise, matter doesn’t have preferences for the forms it takes, so how can a materialist form any kind of justification for ethical beliefs in a strictly material universe?
As I stated in another forum topic:
A mass murderer could legitimately hold, “I am just rearranging molecules when I shoot these hundred people. Whether molecules form a human being or a corpse or humus really makes no difference to the ground of our physical being - matter. Nothing in matter compels me to act in a certain way because nothing in matter gives a reason for preferring one form over another.”
Matter can have no ultimate plan because it doesn’t think, isn’t alive and has no preferences.
I will restate another part of that post because you really had no answer to this point, either:
Even if you impose some kind of “survival of the fittest” schema on matter, matter provides no justification for preferring survival or life over some other form it might take. Life is pretty tenuous and it is merely just another form that matter has taken. Why should life, a centipede or a diamond be preferred by matter itself over coal, for example?
There can be no ethical reason for valuing one form over another that is grounded in the material universe. On earth, human beings value some forms over others for decidedly trivial reasons, but separated from these merely human preferences, matter makes no such distinctions of value. Even if all life on Earth went extinct, it wouldn’t make an iota of difference to the universe – if matter is all there is.
If you then resort to being parochial and anthropocentric about ethical matters and we, for the sake of argument, might grant you that humans have some inconsequential “right” to value life. Okay, survival is important to us as human beings. Let that be the basis for ethical behaviour!
We would then have to admit all kinds of bizarre behaviours including “nazi” dreams of ideal races that are “fittest” to continue the human species.
If one arrangement of molecules over here, let’s call it “Hitler” wishes to change other arrangements of molecules, say in gas chambers, matter itself cannot sanction him. It can make no claims on human behaviour and neither can we use it to “justify” ourselves in opposing Hitler. We could, in response to Hitler, act in whatever way we “wish” just because we desire it, but our response cannot have claim to be qualitatively better than Hitler’s if you use materialism as the ground of metaphysics, knowledge and ethics.
If survival of life is important to us in our little human community, then Hitler could legitimately say, “Let’s clean the gene pool of everything weak and unfit because we desire survival of humanity.” He would – if strict survival of the fittest becomes our goal – seem to have been endowed with great foresight, because “persons” are, after all, merely chemical clouds of brain processes after all. Once materially rearranged, these unfit ones simply dissipate into the cosmos, no harm done – and they leave room for others who are more fit to survive. Hitler would have a point about keeping humanity fit for survival.
It seems to me that materialism as the ground of metaphysics, epistemology and ethics allows for some pretty messy and contemptible ideas. Once the human “person” becomes a shadowy non-entity and matter, i.e., molecular and chemical processes takes precedence, ethical behaviour has lost all substantive ground of meaning – a radical relativism is the result.
