Nursery Rhyme

Visible to anyone in the world

Mr. Small was nothing at all

And Mrs.Tiny less

And Missy Minature a dot.

God bless them all, God bless.

Me in a rare cheerful mood

New comment

I have sometimes surprised people because I can recall and explain de Morgan's Law that

not (A and B) = (not A) or (not B)

and

not (A or B) = (not A) and (not B)

I remember it because I find it elegant.

Clever chap, that de Morgan.  He also wrote one of my favourite poems (of which I was reminded by yours):

Little fleas have littler fleas
Upon their backs to bite 'em.
And littler fleas have still littler fleas
And so on, ad infinitum.

But I see that with my usual incompetence of memory for quotes, I do not recall it correctly: https://en.wikipedia.org/wiki/Siphonaptera_(poem) .  And now that I see it is a parody of a satire about poets, I am even more impressed with the genius of de Morgan.

And I think I'm doing well just because I can remember one of his laws of logic.

I always remembered

Big fleas have little fleas upon their backs to bite 'em,
And little fleas have lesser fleas, and so, ad infinitum.

which I thought was by Swift, but I see I was wrong and it is De Morgan's version.

I liked the others on the WP page as well, very good!

I feel if I tried to hold a candle to the likes of de Morgan and Swift, I would burn my fingers with hot wax, wreck the carpet, then find I had arrived a week early.

Or - crushingly - two or three centuries too late.

Who are the Jonathan Swifts of today?  Are there any?
