Many people are interested in spirituality. But there is an unfortunate among of superstition and pseudoscience attached to the subject. Many atheists, agnostics, and Humanists avoid the term because it is associated in the minds of many with religion.
But spirituality is not necessarily connected to religion. Sam Harris has shown this in his book Waking Up. But it is important that we think carefully about how we approach the subject of spirituality. We want a personal relationship with reality, not myths and superstitions.
So here are a few guidelines in approaching the subject. Spirituality should never contradict science. Spirituality should never go beyond science in objective reality. Spirituality should never confuse the objective and subjective. Spirituality should never go against reason. Spirituality should follow the best evidence. Spirituality should develop the mind. Spirituality should mature the emotions. Spirituality should discipline the will. Spirituality should utilize the body. Spirituality should embrace the senses. Spirituality should conquer the ego. And spirituality should give meaning to life.
Nothing in here about God or gods. No religion required, as many who claim to be spiritual but not religious have found. Humankind is incurably spiritual, it is a part of our nature. We don’t need to deny spirituality, we need to guide it to connect to reality as it really is. These guidelines are a start in that direction.
