In Plato's Sophist he tackles the question of being and not-being. Can something that "is" be "not" or to put it in perspective can an idea that is true be false?
If somebody has the idea of winning the lottery, and he knows for a fact winning the lottery exists, and he clings to this idea knowing he can win the lottery but at present he has not, how can an idea that is true, be false.
Of course the conventional view is that hope, fate and luck have a big say in the matter but the person with the knowledge or opinion of all these facts, and attempting to bring into being that which is, how can he avoid being sucked into the paradox of that which "is" "is not" and that which "is not" "is"?
Is his idea of winning true or false, and if true, how does he avoid continuously deceiving himself if at any given moment, after acquiring the necessary tickets, he has not won?
