For 200,000 years our horizon was limited by our size.
But over the last 100 years or so our horizon has extended to include the unimaginably small and the unimaginably large.
Our horizon has extended from the heart of the atom to the shape of the universe.
And we found the atom is not what we thought it was, and nor is the universe.
In fact the atom and the universe are quite counter-intuitive.
While the things we can relate to our physical size remain intuitive.
And so we now have a bifurcation in human culture - those who are intuitive and those who are counter-intuitive.
And those who are counter-intuitive are invariably literate and numerate.
And it is only the literate and numerate that can understand the modern world of science, economics and politics.
And it is the intuitive that are left in the world of astrology, religion, the New Age, pseudo-science and tribalism.
C.P. Snow spoke of these two cultures in, "The Two Cultures", in 1959.
And I hardly need to point out that the illiterate, innumerate, tribal world of Islam is at war with the literate, numerate, democratic West.
And the war is about size.
The intuitive only have to look about them to see they are right. While the counter-intuitive only have to look through a microscope or a telescope to see they are right.
Unfortunately for the intuitive, the cat is out of the bag.
In fact two cats - one very small and one very large.
And the counter-intuitive cats are among the intuitive pigeons.
