A headstone is shown, topped with the name "John Venn". Below is shown a Venn diagram with two side-by-side circles, overlapping a bit in the middle. The first circle is labeled "Eternity A" and the second circle is labeled "Eternity B". The overlap is labeled "1834 - 1923".

I love a good Venn diagram, despite failing appallingly at being able to do the proper numbers ones at school.

Happy Birthday John Venn

I might dig out some of my favourite songs in Venn diagrams. (I might not.)

"We endeavour to employ only symmetrical figures, such as should not only be an aid to reasoning, through the sense of sight, but should also be to some extent elegant in themselves."
