If you're #turing and #Wittgenstein aware, you just have to read th Wittgenstein Cambridge course on #mathematical #fundation (Where Turing was the Wittgenstein pupil), you can have one here: http://digital2.library.pitt.edu/islandora/object/pitt%3A31735061817957/viewer#page/1/mode/2up
The bilingual edition French/English is like this: https://www.amazon.fr/Cours-sur-fondements-math%C3%A9matiques-fran%C3%A7ais-anglais/dp/2905670363/ref=sr_1_4?ie=UTF8&qid=1515043896&sr=8-4&keywords=wittgenstein%2Bfondement%2Bmathematiques
@borko Yup but in fact their work took place in the same period and they worked on the same subject. They definitively knew each others (at least they were involved in an epistolary relationship i think). Thereś a comic book about this story: Logicomix. It's an awesome reading about this period even if there are some impossibilities (historically speaking). You can find it here: https://archive.org/details/Logicomix-Comic-EarlyLifeOfBertrandRussell
@dervishe Whoa, I didn't know that!
It's like all these guys (Turing, Godel, Russell, Wittgenstein) knew each other.
