Wittgenstein establishes the perimeter:
The boundary of my language represents the boundary of my world.
— Ludwig Wittgenstein (Tractatus, 1922)
If my language is science, what delineates my world? Replies Victo Hugo, 62 years earlier:
Science says the first word on everything, and the last word on nothing
— Victor Hugo (Post-scriptum de ma vie, written 1860)
