Ideas of David Hilbert, by Text
[German, 1862 - 1943, Professor of Mathematics at Königsberg, and the Göttingen.]
1899
|
Foundations of Geometry
|
|
p.9
|
9546
|
Euclid axioms concerns possibilities of construction, but Hilbert's assert the existence of objects [Chihara]
|
|
p.17
|
18742
|
Hilbert's formalisation revealed implicit congruence axioms in Euclid [Horsten/Pettigrew]
|
|
p.25
|
18217
|
Hilbert's geometry is interesting because it captures Euclid without using real numbers [Field,H]
|
|
p.42
|
13472
|
Hilbert aimed to eliminate number from geometry [Hart,WD]
|
1899
|
Letter to Frege 29.12.1899
|
|
p.51
|
15716
|
If axioms and their implications have no contradictions, they pass my criterion of truth and existence
|
1900
|
On the Concept of Number
|
p.183
|
p.129
|
22293
|
Hilbert said (to block paradoxes) that mathematical existence is entailed by consistency [Potter]
|
|
p.148
|
10113
|
The grounding of mathematics is 'in the beginning was the sign'
|
|
p.153
|
10115
|
Hilbert substituted a syntactic for a semantic account of consistency [George/Velleman]
|
|
p.156
|
10116
|
Hilbert aimed to prove the consistency of mathematics finitely, to show infinities won't produce contradictions [George/Velleman]
|
6.7
|
p.154
|
8717
|
Hilbert wanted to prove the consistency of all of mathematics (which realists take for granted) [Friend]
|
1904
|
On the Foundations of Logic and Arithmetic
|
p.130
|
p.130
|
17697
|
The existence of an arbitrarily large number refutes the idea that numbers come from experience
|
p.131
|
p.131
|
17698
|
Logic already contains some arithmetic, so the two must be developed together
|
[03]
|
p.1108
|
17963
|
The facts of geometry, arithmetic or statics order themselves into theories
|
[05]
|
p.1108

17965
|
The whole of Euclidean geometry derives from a basic equation and transformations
|
[05]
|
p.1108
|
17964
|
Number theory just needs calculation laws and rules for integers
|
[09]
|
p.1109
|
17966
|
Axioms must reveal their dependence (or not), and must be consistent
|
[53]
|
p.1115
|
17967
|
To decide some questions, we must study the essence of mathematical proof itself
|
[56]
|
p.1115
|
17968
|
By digging deeper into the axioms we approach the essence of sciences, and unity of knowedge
|
p.184
|
p.66

9636

My theory aims at the certitude of mathematical methods

p.184
|
p.184

The idea of an infinite totality is an illusion

|
p.196
|
p.174
