“There are as many different subterranean stages as there are varying works, as there are extractions. What emerges from these deep excavations? The future.
The deeper one goes, the more mysterious are the toilers. The work is good, up to a degree which the social philosophies are able to recognize; beyond that degree it is doubtful and mixed; lower down, it becomes terrible.
At a certain depth, the excavations are no longer penetrable by the spirit of civilization, the limit breathable by man has been passed; a beginning of monsters is possible.
The descending scale is a strange one; and each one of the rungs of this ladder corresponds to a stage where philosophy can find foothold, and where one encounters one of these workmen, sometimes divine, sometimes misshapen.”
