One famous quotation by Terence reads: "Homo sum, humani nihil a me alienum puto", or "I am a man, I consider nothing that is human alien to me." This appeared in his play Heauton Timorumenos.
My version of Jakobson's paraphrase, which I sent to a list member a little while ago, is:
"I am a linguist; there is nothing in linguistics that I consider foreign to me."
Perhaps the List in general might find this of interest.
Best wishes,
