An asynchronous discussion on limits of science

Wittgenstein, Ludwig                          

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)
