The other part of it, which is essential for understanding what  
Hilbert was saying, is "In the domain of finitary propositions". He  
is speaking about the methodological position he wants to take  
(finitism) in order to prove the consistency of what he calls the  
laws of Aristotelian logic. Further down in the same paragraph: "we  
just do not want to renounce the use of the simple laws of  
Aristotelian logic..."
