For many of the same reasons as monarchies, dictatorships are inherently warlike.
Monarchy is not inherently bad, and there have been fine kings and queens in history.
Egypt is known to have laid claim to the southern half of Palestine from early times, and consequently the extension of the name of Egypt beyond the limits of Egypt and of the Sinaitic peninsula, is inherently probable.
The sand-hills are not inherently infertile; the soil never bakes, is always receptive of moisture, absorbing water like a sponge and holding it well.
The idea of the endosperm as a second subsidiary plant is no new one; it was suggested long ago in explanation of the coalescence of the polar nuclei, but it was then based on the assumption that these represented male and female cells, an assumption for which there was no evidence and which was inherently improbable.
