I probably have said this before, but who knows....?
It is not so much René Descartes' "I think therefore I am" that is true, but rather, unless I'm off by lot, "I want, therefore I am."
There is nothing wrong with thinking, which is a perfectly good human function. But as the T-shirt aptly observes, "Don't believe everything you think." It is the wanting that muddies the waters, I suspect.
Or maybe I am just swimming in quicksand yet again.
