Naturalism as a philosophical stance rejects the possibility of supernatural phenomena, describing such phenomena as misunderstood natural phenomena or falsehood. This preconception necessarily precludes the existence of God.
Science typically affects methodological naturalism, the idea that only those influences that can be measured and quantified, can be considered as part of an experiment. This philosophy is essentially agnostic, but is adapted by scientists of all religions for the purpose of their work. Creation scientists reject methodological naturalism, holding that its inherent materialism rejects God's existence and thus any possibility of a relationship with Him.
Philosophical naturalism is the concept that human beings have no soul or spiritual body, that there is no afterlife or heaven or hell, and that all supernatural phenomena, causes or beings are merely figments of human imagination.
Moral naturalism rejects divine revelation as the source of ethics, holding that morals emerged from the emergence of the best course for survival as a society, much as instincts emerge as the best course for survival among animals in the wild.
John Morris, PhD., wrote:
- Naturalism (i.e., naturalistic evolution) is often desirable, for it seemingly frees us from the authority of a Creator God. Without a God to whom we are accountable, we are free to live as we choose. College students, often surrounded by hedonism are particularly ripe for wrong thinking, and many never recover.
