“Plato in his allegory of the soul—in the Phaedrus—though he apparently divides the passions which draw the human chariot into two classes, the heavenward and the earthward—figured by the white horse and the black horse respectively—does not recommend that the black horse should be destroyed or dismissed, but only that he (as well as the white horse) should be kept under due control by the charioteer. By which he seems to intend that there is a power in man which stands above and behind the passions, and under whose control alone the human being can safely move. In fact if the fiercer and so-called more earthly passions were removed, half the driving force would be gone from the chariot of the human soul. Hatred may be devilish at times—but after all the true value of it depends on what you hate, on the use to which the passion is put. Anger, though inhuman at one time is magnificent and divine at another. Obstinacy may be out of place in a drawing-room, but it is the latest virtue on a battlefield when an important position has to be held against the full brunt of the enemy. And Lust, though maniacal and monstrous in its aberrations, cannot in the last resort be separated from its divine companion, Love. To let the more amiable passions have entire sway notoriously does not do: to turn your cheek, too literally, to the smiter, is (pace Tolstoy) only to encourage smiting; and when society becomes so altruistic that everybody runs to fetch the coal-scuttle we feel sure that something has gone wrong. The white-washed heroes of our biographies with their many virtues and no faults do not please us. We have an impression that the man without faults is, to say the least, a vague, uninteresting being—a picture without light and shade—and the conventional semi-pious classification of character into good and bad qualities (as if the good might be kept and the bad thrown away) seems both inadequate and false.”

As quoted in Genetic Studies in Joyce (1995) by David Hayman and Sam Slote. Though such remarks have often been quoted as Wellington's response on being called Irish, the earliest published sources yet found for similar comments are those about him attributed to an Irish politician:
The poor old Duke! what shall I say of him? To be sure he was born in Ireland, but being born in a stable does not make a man a horse.
Daniel O'Connell, in a speech (16 October 1843), as quoted in Shaw's Authenticated Report of the Irish State Trials (1844), p. 93 http://books.google.com/books?id=dpKbWonMghwC&pg=PA93&dq=%22+make+a+man+a+horse%22&num=100&ei=0YVZSIWXCIiSjgG37bGIDA
No, he is not an Irishman. He was born in Ireland; but being born in a stable does not make a man a horse.
Daniel O'Connell during a speech (16 October 1843), as quoted in Reports of State Trials: New Series Volume V, 1843 to 1844 (1893) "The Queen Against O'Connell and Others", p. 206 http://books.google.com/books?id=zWETAAAAYAAJ&pg=PT108&dq=%22+make+a+man+a+horse%22&num=100&ei=MohZSJ-PK4a4jgG-lLGJDA
Variants: If a man be born in a stable, that does not make him a horse.
Quoted as as an anonymous proverb in Dictionary of Quotations from Ancient and Modern English and Foreign Sources (1899), p. 171
Because a man is born in a stable that does not make him a horse.
Quoted as a dubious statement perhaps made early in his career in The Concise Oxford Dictionary of Proverbs (1992) edited by John Simpson and Jennifer Speake, p. 162.
