throw away the ladder

Wittgenstein’s Ladder, a poem by David Lehman

Not much of a poem. And I have read that LW was not a machine gunner, nor a stretcher carrier in WWI, he operated a search light on a boat (much more apt!). (Ray Monk bio)

But no matter, there’s the epigram:

“My propositions serve as elucidations in the following way:
anyone who understands them eventually recognizes them as
nonsensical, when he has used them — as steps — to climb
up beyond them. (He must, so to speak, throw away the ladder
after he has climbed up it.)” — Ludwig Wittgenstein, Tractatus

Throw away the ladder after you have climbed up it. Is this true for any intellectual effort?
