Ideas of spirits originated with primitive, fear-based, animistic belief systems. There is no universally accepted definition of spirituality. Those who describe themselves as ‘spiritual’ tend to claim access to supernatural beings, states, or mystical realms. It has become cliché to say, ‘I’m spiritual, but not religious.’ People are indeed capable of profound, noetic thought, but incapable of communicating with spirits or deities.
The supernatural cannot exist in a natural universe, thus science has moved beyond ideas of supernatural and paranormal phenomena. A majority of scientists believe in determinism (all effects have natural causes), and empiricism (evidence-based truth). Nor has science found evidence for a creator, intelligent design, or free will. Science has found natural explanations for the former mysteries of miracles, the biblical Genesis, and creation myth. As secular society evolves, spirituality and religion lose relevance and credibility.
Humanists and atheists embrace a secular worldview and philosophy of life, free of supernatural and mystical elements. They reject notions of a theistic god and associated beliefs in an immortal soul destined for an afterlife, a supernatural origin of the universe, the revealed nature of the Bible and the Quran, or a religious foundation for morality.
There are infinitely varying self-concepts of ‘spirituality’ on the beliefs continuum. You are free to define your spirituality or unique beliefs as you choose. Be tolerant of how others define themselves. When they explain their beliefs or spirituality, listen with an interested, open mind—not argumentation, open skepticism, or dismissal.
Live in respectful harmony within the diversity around you.
