First, then, it must be said that in those days things were achieved scarcely inferior to the construction of the Tower of Babel, although as regards divine approval, at least according to human reckoning, strongly at variance with that work. I say this because during the early days of building a scholar wrote a book in which he drew the comparison in the most exhaustive way. In it he tried to prove that the Tower of Babel failed to reach its goal, not because of the reasons universally advanced, or at least that among those recognised reasons the most important of all was not to be found. His proofs were drawn not merely from written documents and reports; he also claimed to have made enquiries on the spot, and to have discovered that the tower failed and was bound to fail becase of the weakness of the foundation. In this respect at any rate our age was vastly superior to that ancient one. Almost every educated man of our time was a mason by profession and infallible in the matter of laying foundations. That, however, was not what our scholar was concerned to prove; for he maintained that the Great Wall alone would provide for the first time in the history of mankind a secure foundation for a new Tower of Babel. First the wall, therefore, and then the tower. His book was in everybody's hands at that time, but I admit that even to-day I cannot quite make out how he conceived this tower. How could the wall, which did not form even a circle, but only a sort of quarter or half-circle, provide the foundation for a tower? That could obviously be meant only in a spiritual sense. But in that case why build the actual wall, which after all was something concrete, the result of the lifelong labor of multitudes of people? And why were there in the book plans, somewhat nebulous plans, it must be admitted, of the tower, and proposals worked out in detail for mobilizing the people's energies for the stupendous new work?

There were many wild ideas in people's heads at that time--this scholar's book is only one example--perhaps simply because so many were trying to join forces as far as they could for the achievement of a single aim. Human nature, essentially changeable, unstable as the dust, can endure no restraint; if it binds itself it soon begins to tear madly at its bonds, until it rends everything asunder, the wall, the bonds, and its very self.
