Hi James:
I think you read retrospectively marginalist concepts were non-exist. The final word on Ricardo has been provided long ago by Sraffa, who did spent some time, I believe, on reading Ricardo and the surplus approach authors views on value theory. You should read it too. 
Best of luck,
Matias

I find it truly amazing that Matias Vernengo would be unable to read an
inverse wage-quantity-of-labor demanded relation in Ricardo's chapter on
machinery, worse yet to have declared that the downward sloping demand
curve was alien to "Ricardo and other classical authors."  How sad.
Would that Vernengo took the trouble to read carefully classical price
(value) theory.

Indeed, in the following paragraph from which I quoted Ricardo's
explanation of the consequence of the RISE of wages on labor's
employment, Ricardo also says: "The same cause that *raises* labour,
does not raise the value of machines, and, therefore, with every
augmentation of capital [funds], a greater proportion of it is employed
on machinery.  The demand for labour will continue to increase with an
increase of capital, but not in proportion to its increase; the ratio
[labor to machinery] will necessarily be a diminishing ratio" (my
emphasis).  And Vernengo doesn't recognize a discussion of the choice of
techniques in that passage?

In fact, Ricardo may be understood here to have been elaborating a
similar point Adam Smith makes in the _Wealth of Nations_. Smith
explains: "So very heavy a tax upon the first necessary of life, must
either reduce the subsistence of the labouring poor, or it must occasion
some *augmentation* [rise] in their pecuniary wages, proportionable to
that in the pecuniary price of their subsistence.... So far as it
operates in the [latter], it must reduce the ability of the employers of
the poor, to employ so great a number as they otherwise might do, and
must, so far, tend to restrain the industry of the country" (_WN_, 2:14;
my emphasis).  I see in Smith's argument, a downward sloping labor
demand curve.  I also recognize in his explanation what we do with the
isoquant-isocost diagram.  In it, we show a reduction in the quantity of
labor demand when the wage rate rises relative to the rental rate for
capital equipment, and also a reduction in output when the funds
(capital) employed in production are unchanged.

Now if Robert would try to answer for himself, why the labor demand
curve would shift to the right, following a leftward movement along it
when the wage rate increases, he might be led to drop that line of his
inquiry.  Simply put, who buys more of something just because it has
become more expensive?  Don't we teach our introductory economics
students never to shift the demand (or supply) curve because a product's
own price changes but rather to move along the curve?
