For the collection of things such as living beings' memories, thoughts, and ideas that cannot be described clearly in words, Daoism called it the soul and spirit, Buddhism called it consciousness, Deities called it the soul, while scientists called it intelligence.
Yet it could not be denied that in Lin Chen's previous life, whether humanity possessed souls had always been an unanswerable question throughout the ages.
After all, in the physical universe of his previous life, there were three criteria for judging whether a theory was mature and scientific.
They were: whether it could reproduce the results of the original theory; whether it could explain results that contradicted the original theory; and whether it could make new, testable predictions.
Since souls could not be verified, nor could anyone predict how to verify them, "souls exist" was neither a scientific theory nor a scientific hypothesis, but a personal conjecture.
Thus, no one had ever known whether they existed.
But in the Chaos Universe of this life, Lin Chen could say with absolute certainty that souls—the Three Souls and Seven Spirits spoken of by Daoism, the indestructible Primordial Spirit, the Natal True Spirit...—truly existed!
