I spent the earlier portion of this evening with my old friend Jeff. As ever, our conversation ranged far and wide. One topic on which we dwelt at length revolved around what constitutes reality and how, at any given point we can be certain that what we are experiencing is real. When one dies, my friend remarked, the world ceases to exist. While I don’t wish to get into whether my dear friend is, in fact right, I had in the back of my mind during the entirety of our conversation a poem by A. E. Housman and, on returning home I felt compelled to look it up. The lines run thus:
“Good creatures, do you love your lives
And have you ears for sense?
Here is a knife like other knives,
That cost me eighteen pence.
I need but stick it in my heart
And down will come the sky,
And earth’s foundations will depart
And all you folk will die”.
