We will work out one other Syllogisma rather harder one than the lastand then, I think, you may be safely left to play the Game by yourself, or (better) with any friend whom you can find, that is able and willing to take a share in the sport.

Let us see what we can make of the two Premisses—

Remember, I don't guarantee the Premisses to be facts. In the first place, I never even saw a Dragon: and, in the second place, it isn't of the slightest consequence to us, as Logicians, whether our Premisses are true or false: all we have to do is to make out whether they lead logically to the Conclusion, so that, if they were true, it would be true also.
