In the course of the eighteenth century, there arose a notorious rift between faith and knowledge. Faith lacked experience and science missed out the soul. Instead, science believed fervently in absolute objectivity and assiduously overlooked the fundamental difficulty that the real vehicle and begetter of all knowledge is the 𝒑𝒔𝒚𝒄𝒉𝒆, the very thing that scientists knew the least about for the longest time. It was regarded as a symptom of chemical reactions, an epiphenomenon of biological processes in the brain-cells - indeed, for some time it did not exist at all. Yet all the while scientists remained totally unaware of the fact that they were using for their observations a photographic apparatus of whose nature and structure they knew practically nothing, and whose very existence many of them were unwilling to admit. It is only quite recently that they have been obliged to take into their calculations the objective reality of this psychic factor.
