![“It is well known that geometry presupposes not only the concept of space but also the first fundamental notions for constructions in space as given in advance. It only gives nominal definitions for them, while the essential means of determining them appear in the form of axioms. The relationship…” quote by Bernhard Riemann](https://sms4smile.com/quotes/i/d49/bernhard-riemann-79557_axioms_it-is-well-known-that-geometry-presuppos_3108543.jpg)   [Download](https://sms4smile.com/quotes/i/d49/bernhard-riemann-79557_axioms_it-is-well-known-that-geometry-presuppos_3108543.jpg) [Open image](https://sms4smile.com/quotes/i/d49/bernhard-riemann-79557_axioms_it-is-well-known-that-geometry-presuppos_3108543.jpg)

> ““It is well known that geometry presupposes not only the concept of space but also the first fundamental notions for constructions in space as given in advance. It only gives nominal definitions for them, while the essential means of determining them appear in the form of axioms. The relationship of these presumptions is left in the dark; one sees neither whether and in how far their connection is necessary, nor a priori whether it is possible. From Euclid to Legendre , to name the most renowned of modern writers on geometry, this darkness has been lifted neither by the mathematicians nor the philosophers who have laboured upon it.””

Bernhard Riemann
