“I had a feeling once about Mathematics, that I saw it all — 
Depth beyond depth was revealed to me — the Byss and Abyss. 
I saw, as one might see the transit of Venus or even the Lord Mayor’s Show, a quantity passing through infinity and changing its sign from plus to minus. I saw exactly why it happened and why the tergiversation was inevitable: and how the one step involved all the others. 
It was like politics. 
But it was after dinner and I let it go!”

— Winston Churchill
