I propose hedonism, properly understood, as Nature’s built in guidance system. Every normal, healthy animal with a functioning nervous system uses the hedonic system every day of its life. Human animals have the advantage of language and a brain that gathers and stores information it can be taught, so warnings about others’ experiences can be learned. The disadvantage comes with the ability to store misinformation with no experience to use for comparison, so no way to recognize it as such. Without science, as can be observed in the people around us, misinformation gets accepted as good unless it leads to pain early enough to be recognized as the cause. Science is all we have that can be relied on for valid, verifiable data that can steer us straight. Science gives us intentionally gained experience through experimentation and peer review. Only science leads to truth on a verifiable path of exploration.
