Accordingly I wrote to Professor Miller, of Cambridge, and this geometer has kindly read over the following statement, drawn up from his information, and tells me that it is strictly correct:-
The long chains of simple and easy reasonings by means of which geometers are accustomed to reach the conclusions of their most difficult demonstrations, had led me to imagine that all things, to the knowledge of which man is competent, are mutually connected in the same way, and that there is nothing so far removed from us as to be beyond our reach, or so hidden that we cannot discover it, provided only we abstain from accepting the false for the true, and always preserve in our thoughts the order necessary for the deduction of one truth from another.
Theodorus's meaning must be closer to "mere words," since as a geometer he can hardly have turned away from the abstract.
Besides being a scientist, a geometer like Euclid and a mathematician, Pythagoras was a theologian, an aspect of his life that we rarely hear of.
Whether the resemblance goes far enough to accept an undoubted common origin for the Jagellon globe and the "Tross gores" as for our globe and the Lenox globe I cannot decide; but it is not improbable that Boulengier, who was an able astronomer, geometer and geographer (and who also constructed globes) might have made the astronomical-geographical clock which is now one of the treasures of the Jagellon University Library.

The implication of this seems to be that a geometer both does and does not know geometrical truths.
It may be confusing because Goldberg called them polyhedra, a perfectly sensible name to a graph theorist, but to a geometer, polyhedra require planar faces," Schein said.
