To think nothing is simply to lack any thoughts at all, and this may certainly be possible (eg in a dreamless sleep). To think about nothing is to think something, the same as to think about Father Christmas is to think something, even though there is no Father Christmas to think about. So, I can say with some confidence that, yes, it is possible to think about nothing. ThorlokiIt’s perfectly possible to think about nothing; in fact, Jean-Paul Sartre wrote half of Being and Nothingness about it. It is possible to be empty of thought, but is not easy to find and you can’t think your way to it.
