These efforts claim to be based on science, on rationality, with the aim to uphold scientific inquiry. Once thus explained, how dare one question the conclusion?
To question the integrity of these efforts is to be irrational, unscientific, unsophisticated. But really, what are these so-called experts up to? Don't they have an unconscious agenda? Don't they want to deny that which requires them to look more deeply into what is going on?
There is a term for this, it is called "Scientific Reductionism."
Anthropology --> Psychology --> neurology --> biochemistry --> chemistry --> physics --> math?
Each theory absorbed by and explainable by the other.
Descartes' Rules of Method and principle of analysis. Tree of Knowledge.
culture is NOTHING BUT psychological laws
red is NOTHING BUT vibrations
heat is NOTHING BUT movement
anger is NOTHING BUT high adrenalin
Knowledge is NOTHING BUT neurology
... but in each case ask what is "NOTHING BUT? "
All science is an attempt to explain one thing in terms of another, to give the causes of the phenomena.
As you can see, if one is not careful, one is easily convinced that somehow, by saying something, such as an "an out-of-body experience" is simply a biological, neurological event, that somehow the experience has been explained -- that it was an illusion and can now be dismissed.
The mind separates and labels. This is satisfactory to the mind. It allows it to feel secure, and to dismiss that which is not easily labeled.
The spiritual can be denied, but it cannot be dismissed. The mystics throughout generations have been talking about, and pondering this "No Thing." In fact, they have said, from every culture, that this 'nothing' is the essence of all that is.
It is just that, the formless "no thing" that gives rise to all manifestation. The mysterious "nothing" is the spirit that pervades all form. Just having a body is an experience in what? Consciousness. That's all there is.
