Description
Cheerilee gets a special message.Kudos if you get the math bit, though haven't done any predicate logic in about two years so help me out if I've gotten something wrong.
Wasn't planning on doing a comic today.
Happy Valentine's Day, to those of you to which the greeting still applies! (And everyone else too because why leave anyone out.)

Simple enough really. Upside down A means "for all", upside down E means "there exists (at least one)", ∈ means "in" and ¬ means "not". So, ∀x ∈ D is making an assertion about all ponies (on the blackboard D is defined as the set of ponies). Once you know what the symbols mean, making sense of a logical assertion is a simple matter of reading it.
Where it gets more complicated is when you start transforming them. For example, the opposite of "for all X, Y and Z" is "there exists at least one X such that not Y or not Z". But logicians have that covered, no need to worry.

MY STRUGGLE, by Adolf Hitler:
VOLUME I: A RETROSPECT CHAPTER I IN THE HOME OF MY PARENTS It has turned out fortunate for me to-day that destiny appointed Braunau-on-the-Inn to be my birthplace. For that little town is situated just on the frontier between those two States the reunion of which seems, at least to us of the younger generation, a task to which we should devote our lives and in the pursuit of which every possible means should be employed. German-Austria must be restored to the great German Motherland. And not indeed on any grounds of economic calculation whatsoever. No, no. Even if the union were a matter of economic indifference, and even if it were to be disadvantageous from the economic standpoint, still it ought to take place. People of the same blood should be in the same REICH. The German people will have no right to engage in a colonial policy until they shall have brought all their children together in the one State. When the territory of the REICH embraces all the Germans and finds itself unable to assure them a livelihood, only then can the moral right arise, from the need of the people to acquire foreign territory. The plough is then the sword; and the tears of war will produce the daily bread for the generations to come. And so this little frontier town appeared to me as the symbol of a great task. But in another regard also it points to a lesson that is applicable to our day. Over a hundred years ago this sequestered spot was the scene of a tragic calamity which affected the whole German nation and will be remembered for ever, at least in the annals of German history. At the time of our Fatherland's deepest humiliation a bookseller, Johannes Palm, uncompromising nationalist and enemy of the French, was put to death here because he had the misfortune to have loved Germany well. He obstinately refused to disclose the names of his associates, or rather the principals who were chiefly responsible for the affair. Just as it happened with Leo Schlageter. The former, like the latter, was denounced to the French by a Government agent. It was a director of police from Augsburg who won an ignoble renown on that occasion and set the example which was to be copied at a later date by the neo-German officials of the REICH under Herr Severing's regime.

Mate, you have too much free time don't you ?
But I admit, it was a nice read.

Come one, he was the first man to ban smoking in public, to ban vivisection, to protect animals and he came with a great way to reduce overpopulation and to increase the production of soap at the same time!

That is of course very true, he was indeed a great politician. But I love my greatgranfather to him....so I don't suppose you understand everything. Or you do, but are too absorbed in your greatness to,notice.

It says that for element (x) in the set of all ponies there exists anothere element (y) in the same set so that the condition x loves y, is true. AKA everypony loves somepony.
The chalkboard explains it, or you read up on formal logic.

Oh, I see....
Hmm, my mistake in such case, I was being ignorant of this information...
Math, isn't quite my things

The bit on the envelope actually a slight variant of the statement if I've written it correctly. It'd mean "everypony is loved by somepony."

What's funny is that, as written, it doesn't exclude the possibility that x=y (that the only pony who loves the pony in question is him/herself). Methinks the CMC understand their predicate logic, but need to brush up on their set theory, since ∀y∈Dp, ∃x∈Dp−{y}: L(x,y) is probably what they meant.
