Full Idea
To dissociate each thing from everything else is to destroy totally everything there is to say. The weaving together of forms is what makes speech [logos] possible for us.
Clarification
'Logos' might translate as an account, or as understanding
Gist of Idea
If we see everything as separate, we can then give no account of it
Source
Plato (The Sophist [c.358 BCE], 259e)
Book Reference

A Reaction
This I take to be the lynchpin of metaphysics. We are forced to see the world in a way which enables us to give some sort of account of it. Our metaphysics is 'inference to the best logos'.
