There is a book called ‘Henri, le Chat Noir’, written by William Braden.
It also has a sub-title: The Existential Mewsings of an Angst-Filled Cat, so we can tell that Henri inclines to the existential rather than the essential school of philosophy.
For copyright reasons the picture is not of Henri himself but another cat of the same name.
Unlike the book of napping cats I referred to in an earlier post, the quotations are not from authors musing on the subject of cats but (so Braden would have us believe) by Henri himself.
Henri makes a number of deep points, but this is my favourite:
‘I sleep because every time I open my eyes, the world is still there.’
