Krishnan Guru-Murthy pushed himself back in his chair, clearly feeling more than a little frustrated at the very idea of a Minister for Loneliness. “Can you just give an example of how you might tackle one form of loneliness?” asked the Channel 4 interrogator, keen to find some solid ground in the discussion, something positive and concrete that the Government might actually do to tackle loneliness.
“Set up a metric” was the first answer given by the new Minister, Tracey Crouch. Rightly dissatisfied with the idea that simply measuring loneliness could count as an example of how to tackle it, Guru-Murthy asked again: “Just give me one example?” Something, anything, he was pleading. But concrete example there was none. “Loneliness is subjective,” said the Minister “so it’s very difficult.”
Perhaps I should start again. Set the scene in a completely different way and in a completely different century.
“I think therefore I am” is probably the most famous phrase in all of philosophy. It is also one of its greatest mistakes. For with this phrase, René Descartes – the so-called father of modern philosophy – led modernity into a cul-de-sac from which it is still struggling to escape. The back story is this: Descartes’ big intellectual project was to doubt everything that it was possible to doubt with the aim of finding something so solid and certain that he could build the rest of knowledge upon it.
Anything that could possibly be doubted was to be rejected. Only the completely indubitable would suffice. And here he discovered one thing – that although he could doubt pretty much everything, the one thing he could not doubt was that there was something doing the doubting; that is, he couldn’t doubt his own existence. And this was to be the basis for his project. I can know my own existence without a doubt, he insisted. This is the starting point. I think therefore I am.
The problem is the next step. For although I know that I exist, it’s not at all straightforward to know that anyone else exists with anything like the same certainty. How do I establish a connection, a bridge from the certainty of my existence over to the certainty of yours?
