The empirical validation of some fragmentary remnant of tradition always comes too late and counts for very little. This is because the truth of tradition is eternal, i.e. outside duration, invariant, primordial, whereas empiricism is always bound by the limited interval of observation and can never prove or disprove any principle that operates in cycles of a breadth that exceeds that interval. The modern conceit is that whatever resides outside the possibility of phenomenal observation is unknowable. It ignores and devalues faculties receptive to other, and superior, forms of knowledge. Consequently, there is something childlike about the enthusiasm that greets the occasional scientific validation of some truth that tradition understood implicitly, as if tradition had all these millennia been waiting for modern science to come along and give it a proper grounding. For instance, one can only be amused by the importance currently assigned to the scientific validation of sexual difference, a validation utterly trivial when compared to the vastly richer knowledge of sexual difference and its implications available to the ancients.
The wisdom of tradition is not amenable to empirical validation. Today, this wisdom can only reveal itself negatively, via the dismal consequences of what has replaced it.
