 So, on the assumption that he would have accepted that “there will or will not be a sea-battle tomorrow” is equivalent to “there will be a sea-battle tomorrow or there will not be a sea-battle tomorrow”, he would, it seems, have accepted LEM2. How could this be? Well, what stops its being true that there will be a sea-battle tomorrow is that there is nothing yet to determine that it is true. But there is something to determine that there will be or will not be a sea-battle tomorrow; in the nature of things one or the other must occur. So it is now true that there will be a sea-battle tomorrow or there will not be a sea-battle tomorrow.
