Bruce Greyson in a paper published in the Journal Humanities states that, “Near-death experiences (NDEs) are vivid experiences that often occur in life-threatening conditions, usually characterized by a transcendent tone and clear perceptions of leaving the body and being in a different spatiotemporal dimension.”

NDEs have been reported throughout history and across various cultures, with many interpreting them as proof of life after death or the continuation of existence beyond the death of the physical body.

Dr. Eben Alexander, a neurosurgeon, experienced his own NDE during a week-long coma induced by a brain illness. During this experience, he reported traveling outside his body to another world, where he encountered an angelic being and the maker of the universe. He interpreted his experience not only as evidence that consciousness exists outside the mortal body but also as proof of God and heaven.

Socrates believed that the soul, a concept encompassing not only consciousness but also the whole psyche of a person, was immortal and existed in a realm beyond the physical world. According to the Platonic concept of “anamnesis”, the soul is temporarily housed in the mortal body until the body’s death, at which point it returns to a “spiritual” realm. Socrates firmly believed that because the soul is immortal, it is imperative to live a moral and virtuous life to avoid damaging the soul.

Zeno of Citium and the Stoics, following in Socrates’ footsteps, developed the concept of “pneuma” or spirit, which they viewed as a physical substance that returns to the cosmos after the death of the body. They believed that the universe is a living being, a concept known as “pantheism,” and that pneuma or souls are part of the greater universal whole.

Omniscience–Omnipresence.
