The chemist may tell me that the chemical analysis of a lump of coal gives the same result as the chemical analysis of a diamond, to which any man capable of using his reason at all will reply that upon a very large number of other lines of analysis, colour, touch, combustibility, hardness and softness, economic value, prevalence (and so on indefinitely), the two are not the same. No analysis is complete, and if we had made no conscious analysis at all, we could still perceive at once that a lump of coal is not a diamond.
It is just the same with these pseudo-scientific attempts to disprove obvious truth. They pullulate and they are all equally ridiculous because they deduce from insufficient data. The existence and differentiation of the Jewish people as a race ethnically and as a nation politically is as much a fact as the existence of coal or
