Re: [isabelle] Is Isabelle the right tool for me?
Thanks for your answer. Anyway I have a problem at installing
Isabelle/ZF in that, after having unpacked the bundle and ZF under
/usr/local, I can't run isabelle tty. It says:
/usr/local/Isabelle2009-1/bin$ ./isabelle tty
Unknown logic "ZF" -- no heap file found in:
It tries to find ZF instead of HOL because I edited ISABELLE_LOGIC
variable in etc/settings.
Also, why do I need an already built set theory? My goal is to write
set theory from scratch. I'd like to use only the rules of inference
of first order logic (natural deduction).
