Rather than nothing
Lying under the stars, Tom wonders why there is anything at all. Leibniz called it the first question anyone should ask. Why it is hard in a special way, three answers, and a look back at how metaphysics works.
About this video
Tom is lying on the grass on a clear night, looking up at the stars. He wonders where they came from, and where that came from, and so on. Then a bigger question comes: why is there anything at all? Why stars, and grass, and Tom, instead of just nothing?
In 1714 the German philosopher Gottfried Leibniz asked it like this: "Why is there something rather than nothing?" He said it is the first question anyone should ask, since nothing would be simpler and easier than something. The question is hard in a special way. Normally, to explain why something exists, you name its cause: the stars formed from clouds of gas, the clouds came from earlier stars, and so on. But this question is about everything, so any cause you name is one more thing that exists, and part of what needs explaining.
Three answers have been given. Something has to exist: Leibniz said there must be something that exists necessarily, that couldn't fail to exist the way two plus two couldn't fail to make four, and it explains the rest. Many people think of God here; others look for it in the laws of nature or in mathematics; this video doesn't take a side. Its puzzle: can anything really exist the way a number "must"? There is no reason: the world is simply there. In a radio debate in 1948 Bertrand Russell said, "the universe is just there, and that's all." Its puzzle: we look for reasons for everything else, so why stop at the biggest thing of all? Or the question may not be clear: perhaps "nothing" isn't a real possibility at all. Its puzzle: can we be sure, when nothing seems so easy to imagine?
Metaphysics asks questions like these - what is real, what makes something the same thing, what makes you you, what makes things happen, whether you choose freely, what time is - and no experiment settles them. But asking clearly, setting out reasons step by step, testing each answer with a thought experiment and finding the puzzle each leaves makes them clearer. This video goes with the Why Is There Something? lesson of Metaphysics Level 1 on Knaph.
