Robert Paul wrote: "At the beginning of Wittgenstein's wartime notes published as Notebooks 1914-1916—published, that is, in 1961, and revised by its editors and translators in i979—Wittgenstein (as translated) writes, 'Logic must take care of itself,' and soon after calls this a most important finding (or 'most important point'; I haven't the book in front of me)." It must in a certain sense be impossible for us to go wrong in logic. This is already partly expressed by saying: Logic must take care of itself. This is an extremely profound and important insight.
