You must be aware that the reward for labour, and quantity of labour, are quite disparate things.

Justice is the product of nature and labour

It is far from easy to determine whether she [Nature] has proved to man a kind parent or a merciless stepmother.

The skill and the art of the labourer have been overlooked, and he has been vilified; while the work of his hands has been worshiped.

Surely then some distinction between the different kinds of labour, with reference to their different effects on national wealth, must be admitted to be not only useful, but necessary; and if so, the question is what this distinction should be, and where the line between the different kinds of labour should be drawn.

[M]an has always felt and recognised the imperfection of nature, and has never accepted it as law. He broke this law when he took his first step, because his vertical posture challenged gravity, the most universal law of nature. This upright position is not natural to man – it is supranatural – and he has achieved it artificially, through effort (by swaddling and other methods of adaptation). One cannot say of man that he is the creation of nature. On the contrary, he is the result of under-creation, of deprivation, of a natural pauperism which is shared by rich and poor alike; he is a proletarian, a pariah among living creatures. Yet in this lay the origin of his future greatness; deprived of natural cover and means of defence, he had to create all this himself by his own labour. Therefore man values only that which has been created by working, or which expands the area of application of work; it is not difficult to guess that the culmination of this forward movement must be that everything on which human life depends will ultimately be achieved through work, so that humans will depend solely on their labour. Consequently the entire world, the meteorological, telluric and cosmic processes, will be the responsibility of man, and nature will be his work. Man is driven towards this goal by hunger, disease and every other calamity, so that whenever he delays in expanding the area of work, the scope for disasters expands. Thus nature punishes man by death for his ignorance and sloth, and drives him to ever-expanding labour.

Nature pulls one way and human nature another.

Consideration has not been given ... to this big distinction as to how far men work through machines or as machines.

Even economists can't escape the fact that, as commodities go, labour is something out of the ordinary.

Doth Nature draw me, 'tis because,
Unto my seeming, there doth lurk
A lawlessness about her laws,
More mood than purpose in her work.

Nature is usually wrong.

...to be able to say of a representation that it is "exactly like Nature " is by no means equivalent to saying that it is a fine picture.

It is very conceivable, that the labor of man alone laid out upon a work, requiring great skill and art to bring it to perfection, may be more productive, in value, than the labour of nature and man combined, when directed towards more simple operations and objects

I'm afraid that in nine cases out of ten Nature pulls one way and human nature another.
