"Self-esteem. This organ is situated at the vertex or top of the head..."

"... a little above the posterior or sagittal angle of the parietal bones."

In phrenology, self-esteem is: "One of the mental faculties with which an ‘organ’ or ‘bump’ in the cranium is associated; the ‘bump’ itself." That's from the (unlinkable) OED, where I was looking up "self-esteem," after blogging about Monica Lewinsky's 40th birthday and cherry-picking the old Barbara Walters prompt "Where was your self-esteem?"

Monica, had she known phrenology, might have said: Where? It's at the top of my head, of course, a little above the posterior or sagittal angle of the parietal bones.



Too bad I don't have comments or you could supply me with the jokes about Clinton's "organ" and the location of his self-esteem. I won't go there, other than to say that I see that one could. I've got lofty plans for the direction of this blog post.
I want to tell you that the phrenology meaning only goes back to the early 19th century, but the familiar meaning — "Favourable appreciation or opinion of oneself" — can be found in the 17th century, in Book 8 of John Milton's "Paradise Lost" (1667):

For what admir'st thou, what transports thee so,
An outside? fair no doubt, and worthy well
Thy cherishing, thy honouring, and thy love,
Not thy subjection: weigh with her thy self;
Then value: Oft times nothing profits more
Then self esteem, grounded on just and right
Well manag'd; of that skill the more thou know'st,
The more she will acknowledge thee her Head,
And to realities yield all her shows:
Made so adorn for thy delight the more,
So awful, that with honour thou maist love
Thy mate, who sees when thou art seen least wise.
But if the sense of touch whereby mankind
Is propagated seem such dear delight
Beyond all other, think the same voutsaf't
To Cattel and each Beast; which would not be
To them made common and divulg'd, if aught
Therein enjoy'd were worthy to subdue
The Soule of Man, or passion in him move.

That's the angel Raphael advising Adam about loving Eve. Here are the crib notes for Book 8, to sketch out the context. "The more she will acknowledge thee her Head" is not about getting blow jobs.
