It's a flawed approach specifically because it is unsound to support a theory of something which is defined as being beyond the scope of empiricism with empirical evidence.
In any case, we have empirical evidence which is suggestive of reincarnation, a hypothesis (theory?) NOT beyond the scope of empiricism, and this evidence supports the theory of rebirth proposed by various authors, including Hatonn.
For example, "The objective phenomena of ITC is either ignored, or explained with the usual suspects of fraud, delusion or mundane causes."
This hypothesis has been evolving as more has been learned.
The Trans-survival Hypothesis is a theoretical model based on the Survival Hypothesis typically referred to in discussions related to mind-body theory. As an elaboration on the simpler model with accommodations for lessons learned from the study of transcommunication, it is proposed as an update.
In this model, the expression of intention of a personality is limited by how well the personality understands the nature of reality (sometimes referred to as spiritual maturity). The bounding or limiting effect of understanding on expression is referred to as perceptual agreement. Personality and avatar entanglement acts as a transformer providing etheric-physical energetic agreement.
it is clear that the reader must do the work by studying the references. A quick reading without taking time to understand the references and assumptions, or while insisting that the work adhere to the reader's accepted wisdom, will almost always leave the reader wondering what it is all about. You have to do the work.
The hypothesis is comprehensive, and is at least a good draft for further work; however, it will never evolve if academic barriers are not let down and serious collaboration begun.
