“Happiness depends upon ourselves”
An interpretative gloss of Aristotle's position in Nicomachean Ethics book 1 section 9, tacitly inserted by J. A. K. Thomson in his English translation The Ethics of Aristotle (1955). The original Greek at Book I 1099b.29 http://perseus.uchicago.edu/perseus-cgi/citequery3.pl?dbname=GreekFeb2011&getid=0&query=Arist.%20Eth.%20Nic.%201099b.25, reads ὁμολογούμενα δὲ ταῦτ’ ἂν εἴη καὶ τοῖς ἐν ἀρχῇ, which W. D. Ross translates fairly literally as [a]nd this will be found to agree with what we said at the outset. Thomson's much freer translation renders the same passage thus: [t]he conclusion that happiness depends upon ourselves is in harmony with what I said in the first of these lectures; the words "that happiness depends upon ourselves" were added by Thomson to clarify what "the conclusion" is, but they do not appear in the original Greek of Aristotle. Rackham's earlier English translation added a similar gloss, but averted confusion by confining it to a footnote.
