— David Berlinski

“said that in non-Euclidean geometry space has a curvature, but this way of stating the matter is misleading, since it seems to imply a…

— Hendrik Antoon Lorentz

“The question: 'is the Euclidean geometry true?' has no significance for Poincaré, for these is no such thing as one geometry being more true…

— Fulton J. Sheen

— Arthur Stanley Eddington

“Non-Euclidean' became a byword for non-absolute knowledge. It also served to illustrate most vividly the gap between mathematics and the natural world. Mathematics was…

— John D. Barrow

Not that the propositions of geometry are only approximately true, but that they remain absolutely true in regard to that Euclidean space which has…

— Arthur Cayley

“Moreover, there is no known reason why the geometry of space and time should be described by the particular types of curved geometry defined…

I am coming more and more to the conviction that the necessity of our geometry cannot be demonstrated, at least neither by, nor for,…

— Carl Friedrich Gauss

...to characterize the import of pure geometry, we might use the standard form of a movie-disclaimer: No portrayal of the characteristics of geometrical figures…
