Looking for "Why is there something rather than nothing?" quote.

If you search on "Why are there beings at all, and why not rather nothing?",
you will find that it is from his 1929 lecture "What is Metaphysics?".

this question is not about metaphysics

it is about understanding that nothing can never transform

Read the actual question.

I did

I havn't changed my thinking , I've been through this for several yrs

The hell are you talking about?
Do you have a better source for that specific quotation?
If so, let's hear it.

what I'm saying , trying to say , is that , I don't care about the quotation

the question by the thread , the then resolution of the of the question is not about metaphysics at all

get it

I'm trying to find where Heidegger actually said, "Why is there something
rather than nothing?" I'm having trouble finding it in his works.

why does it matter in the end ?

something can transform into different somethings

nothing can not transform into something

I have heard that several other people have posited this question: Descartes, Sartre, and Leibniz. Is this true? Are there others? Thanks

Would it make any less sense to ask why is there not everything?

I suspect that for Heidegger that would be a non-question. Heidegger's dynamic concept of existence (Existenz) was intextricable to the being (Dasein) of a social entity already embedded in the linguistic flux of life*, not a world of things-in-themselves having existence in their own right. (Ding an sich). There was no static "God's Eye View" of everything including the observer. There was only the possibility for an individual to momentarily stand back and contemplate his own conformity (or otherwise). Such standing back was for Heidegger the key to "authentic living".

I also see it as a meaningless question (i.e., non-question). Whenever I open my mouth I am a relativist-constructivist (implying a distinction between ultimate reality (which is beyond speech) and conventional reality (that which is culturally meaningful). Otherwise I just try to keep still.
