virtual A proof that something exists is "constructive "
if it provides a method for actually constructing it .
Cantor }'s proof that the {real numbers } are {uncountable } can
be thought of as a *non -constructive * proof that {irrational
numbers } exist . (There are easy constructive proofs , too ; but
there are existence theorems with no known constructive
proof ).
Obviously , all else being equal , constructive proofs are
better than non -constructive proofs . A few mathematicians
actually reject *all * non -constructive arguments as invalid ;
this means , for instance , that the law of the {excluded
middle } (either P or not -P must hold , whatever P is ) has to
go ; this makes proof by contradiction invalid . See
intuitionistic logic } for more information on this .
Most mathematicians are perfectly happy with non -constructive
proofs ; however , the constructive approach is popular in
theoretical computer science , both because computer scientists
are less given to abstraction than mathematicians and because
intuitionistic logic } turns out to be the right theory for a
theoretical treatment of the foundations of computer science .
