Fair point.<p>What I had originally thought of as an experience machine was drugs that would produce chemically equivalent reactions as those produced from our experiences.<p>Spiritual usually has an anthropomorphic meaning which is what I object to:<p>Defined as &quot;of, relating to, or affecting the human spirit or soul as opposed to material or physical things&quot;<p>Maybe a better way of stating it is that I am not an empiricist that believes that sensory experience is the end-all be-all.
