It would be sound to say that if something can occur or be controlled 100% of the time, it would lend itself to credibility. But despite the inconsistency of success, so very many people have experienced the clinically unexplainable, and these abilities should not go ignored.

Unfortunately, the unexplained breeds fear, and (as mentioned previously regarding our species' shortcomings) this leads more often than not to negative regard, in some cases sheer panic. And, characteristic of our species' social development (or lack thereof), that which we do not understand and become fearful of often becomes associated with some disembodied entity of ominous intent. And why? All because we lack the technology to clinically recognise it.

So much we take for granted nowadays. Heavy machines that fly, tiny machines which communicate with people halfway across the world. Only a few decades earlier, a computer with a fraction of the memory typical of a laptop computer would have taken up a room the size of a gymnasium. Imagine what these would look like to someone from the 18th century. Or the 16th century. And what about our assorted scientific and anthropological revelations? We'd all be burned at the stake for sure!

The use of scents or colours in oils and candles - which have been proven to have a definite effect on the mind and body - would have been grounds for a witchhunt centuries ago. When did this application find acceptance in the mainstream? Previously, these practises were almost exclusive to practitioners of witchcraft, at best folk healers. When our society was at last able to study these properties and their effects, we had reached a point in our technology when these practises could be acknowledged within present scientific parameters. WE BECAME CAPABLE OF ACKNOWLEDGING THEM, hence they became accepted.

Yes, we had evolved to a point where we were ready to accept that uses of colours and scents can be legitimate therapeutic pursuits, without attributing them to any supernatural ability or the presence of some ominous entity.

But we have a long way to go. Our technology can barely detect or monitor phenomena on a grand scale with any reliability. We're simply not ready...
